TL;DR: AI app builders all generate working first versions from prompts but differ in how much design, data, and logic you can edit without code. Choose based on whether you read code and how often you’ll change the app.
Lovable, Replit, and Bubble can all turn a description of your app into a working first version. The harder choice comes after that, once customers depend on the app and you need to fix it, change it, and grow it.
That’s where these three AI app builders differ most. Each one shows you a different amount of the app you’ve built, and each asks for a different level of technical skill when you want to change how it works.
This comparison covers how each platform handles the work after the first draft, what it costs to run the app you build, and how much technical skill each one takes, so you can choose the one that fits the app you plan to run.
What’s the main difference between Lovable, Replit, and Bubble?
The main difference is how much of your app you can see and change without code. Lovable and Replit generate traditional code, and while Lovable lets you edit text visually and Replit lets you edit UI, content, and layout, the logic and data stay in code on both. Bubble is a fully visual app builder, where the design, data, privacy rules, and logic are all visual and editable, with no code required.
Lovable and Replit get a first version up fast. If you don’t read code, though, changing how the app works means describing the change in another prompt, spending credits, and trusting the result. Over time, small misreads add up, and the app can drift from what you imagined.
On Bubble, the Bubble AI Agent generates every layer of your app, and all of it shows up in the visual editor, where you can see it and edit it by hand without using AI credits, if you want. Logic reads as step-by-step sequences called workflows, like “When someone signs up, send a welcome email.” You build with AI without giving up control, so the app keeps working the way you imagined.
What is an AI app builder?
An AI app builder is a platform that turns a plain-language description of an app into a working first version, including the user interface, database, and logic. They range from tools for quick prototypes to platforms for apps you plan to launch, run, and keep improving.

How we evaluated these platforms
We compared these platforms across the whole process, from the first prompt to a version ready to launch. For each one, we looked at how the platform plans and generates a first version, the quality of that first version, and how much of it you can change yourself, whether by prompting, editing visually, or working in the code.
Then we looked at what it takes to keep the app running and growing: fixing it when the AI gets something wrong, building for native mobile, protecting your data, working with a team, deploying and hosting, connecting other tools, and what all of it costs. We checked competitor facts against each tool’s own site and docs.
Lovable vs. Replit vs. Bubble at a glance
Here’s a quick summary of how these three platforms compare and who they’re best for:
- Lovable: Best for design-forward prototypes and landing pages. It generates polished UI using React and Tailwind CSS. You can only edit text by hand, so other changes, including backend behavior, go through AI prompts or the code. It has a free plan, with paid tiers starting at $25/month ($21/month billed annually).
- Replit: Best for builders who want AI to set up a full-stack app in one place and are comfortable with that app living in code. You build by chatting with Replit Agent, which sets up the database, auth, and hosting automatically, and a visual editor handles quick UI edits. It has a free tier, with paid plans starting at $18/month billed annually, or $20/month billed monthly.
- Bubble: Best for founders and teams building a business they’ll keep changing. It’s a fully visual AI app builder for web and native mobile apps, and everything the Agent builds, you can read and change yourself without writing code. Getting started is free, and paid web plans start at $32/month billed annually or $39/month billed monthly.
Here’s how the three platforms compare across the factors we considered:
| Lovable | Replit | Bubble | |
|---|---|---|---|
| First version | Polished UI from minimal prompting. Deeper features can take more prompts or code. | A full-stack app in code, with the database, auth, and hosting set up automatically. | A working frontend, a database with sample data, and the workflows that connect them, all in one pass. |
| Design capabilities | Responsive design and AI-powered editing, plus inline visual editing for text. | Responsive design generated by Agent, plus a visual editor for direct UI, content, and layout edits. Complex logic still requires Agent or code. | Responsive design generated and edited with the Agent, plus a drag-and-drop visual editor for pixel-level control. |
| Native mobile app support | Focused on web apps. App store distribution requires a third-party wrapper. | Generates React Native mobile apps with AI and deploys via Expo. Code editing is required for complex logic. | Builds native iOS and Android apps in the visual editor and publishes to the App Store and Google Play Store. Shares backend and data with your web app. |
| Collaboration | Real-time collaboration and version history on every plan, including Free. Assigning roles like Viewer, Editor, and Admin takes a paid plan. | Real-time co-editing, workspace roles (Member, Guest, and Viewer), and GitHub integration. | Real-time collaboration with adjustable permissions for each collaborator, depending on your plan. |
| Backend and database support | Built-in backend via Lovable Cloud (built on Supabase), with optional external Supabase integration. | Built-in PostgreSQL database, auth, and App Storage, set up automatically. Schema and access rules live in code. | Built-in visual database with privacy rules you can see and edit, with no separate setup or extra service to pay for. |
| Security and compliance | SOC 2 Type II compliant and ISO 27001:2022 certified. Basic row-level security policies are set up automatically, but builders are responsible for reviewing app-level access rules. | SOC 2 Type II compliant, running on Google Cloud infrastructure. App-specific security is the builder's responsibility, though Replit runs automated checks on generated code. | SOC 2 Type II compliant, with privacy rules the Agent creates for each data type and, on paid plans, a security dashboard that flags issues to fix. |
| Deployment/hosting | One-click deployment with built-in hosting via Lovable Cloud, or sync your code to GitHub and deploy to hosts like Netlify or Vercel. | One-click deployment with Static, Autoscale, Scheduled, or Reserved VM options. | One-click deployment, with built-in hosting and auto-scaling on paid plans. |
| Code ownership and portability | Download your codebase on paid plans, and sync it with GitHub, GitLab, or Bitbucket on every plan, so you can move or self-host the code. | Full code access in the workspace, with a zip download and two-way GitHub sync, so you can move or self-host the code. | You own your app's design and data. To move to code, you can export your app with the Bubble MCP (beta), which lets an AI agent rebuild it in code you own and host. |
| Technical expertise | Less technical than many AI builders, but a technical background still helps with iteration and launch. | Approachable to start, since you can build by chatting with Agent. Reading code helps once you're changing logic and data, which live in code. | Built for builders who don't write code but want to see and change the design, data, privacy rules, and logic. Visual tools take some learning, but far less than code. |
How each platform builds your first version
Here’s what going from a prompt to a first version looks like on each platform.
Lovable and Replit have similar workflows. Both start with a prompt, then bring you to a split-screen view with the AI chat on the left-hand side and the code or preview of your app on the right. Replit also includes a visual editor for direct UI, content, and layout edits.
On Bubble, building starts with a planning session. You describe your idea to the Agent, which asks clarifying questions and drafts a plan with the main features for you to approve. If you’d rather skip the planning session, you can generate your app right away.
Once you approve it, the Agent generates your app, and you land in a Preview tab with the Agent open beside it. From there, you can keep chatting to generate or edit elements, workflows, and logic, or switch to the visual editor whenever you want precise control.
With Bubble’s visual editor, you don’t need a split-screen view of chat and code. You preview your app and edit it in the same place. As a result, Bubble’s development workflow will probably feel more familiar if you don’t write code, or if you’re used to visual, drag-and-drop editors like WordPress or Squarespace.
Here’s how their development workflows compare:
| Lovable | Replit | Bubble | |
|---|---|---|---|
| Generates a project plan to review first | ✅ Via Plan mode, before Build mode makes the changes | ✅ Via Plan mode, before Agent makes the changes in Build mode | ✅ Via a planning session with the Agent |
| Provides a visual preview of your app | ✅ | ✅ | ✅ |
| Builds your app as code | ✅ | ✅ | No. Your app is fully visual, with no generated code. |
| Allows you to edit your app visually | Partly. Limited to inline text edits and sketch annotations. | Partly. The visual editor supports direct UI, content, and layout edits. Deeper application logic and backend behavior still require Agent or code. | ✅ |
| Allows you to edit the code of your app directly | ✅ Via the code editor (paid plans only) or GitHub sync | ✅ | No generated code to edit, though you can add custom code if you want |
App output quality
Every AI app builder’s first draft needs some iteration. The more complete it is, the less you’ll need to fix before launch.
Lovable, Replit, and Bubble all generate a working first version, but the quality shows up in different places: how polished it looks, how well it holds up when tested, and how complete it is.
Lovable
Lovable’s first drafts are especially polished visually. Its React and Tailwind CSS output tends to look finished with very little prompting, with clean layouts and consistent spacing.
Functionality is where the first draft usually needs more work. Deeper features can come out incomplete, and because the logic lives in generated code, fixing them means another prompt or a trip into the code.
Replit
Replit’s first draft is a full-stack app in code, with a built-in database and Replit Auth when your app needs logins. In Power and Max Mode, Agent can click through your app in a real browser and fix issues it finds, billed by effort like other Agent work.
As on any platform, complex features usually take more than one pass. The preview shows how the app looks and behaves, but if you don’t read code, judging what’s underneath means relying on Agent’s summary.
Bubble
Bubble’s first drafts are especially complete. Because the planning session settles the features first, the draft includes responsive pages, workflows, a database with sample data, and privacy rules for each data type, so the app works from the start.
Some features will still need another pass, especially in complex apps. You can check the quality of the draft without reading code, since every page, workflow, and data type the Agent created is laid out in the editor.
Customizability
If you’re building a business on your app, you’ll eventually need to customize it beyond what AI generates. You can do that through AI, visually, or in code, and each platform supports those three to a different degree.
AI-generated customizations
In Lovable, AI chat is the main way to make changes. You can talk through an idea in Chat mode, draft a plan you can edit in Plan mode, and make the change in Build mode. Plan and Build messages use credits, and the changes land in code, so there’s no visual logic to check what the AI did.
In Replit, you make changes by chatting with Agent. Plan mode lets you talk through a change before Agent touches any code, and Free Mode covers everyday changes within an allowance, while bigger jobs in Power and Max Mode are billed by effort. Agent’s changes also land in code, so if you don’t read it, you’re relying on Agent’s summary to know what changed.
On Bubble, you can make changes by chatting with the Agent, which can generate or update workflows, data, and design. Building and editing with the Agent uses AI credits from your plan’s monthly allowance. If you prefer to work from a tool you already use, the Bubble MCP lets you build from Claude, Codex, or ChatGPT, which doesn’t use AI credits, though you’ll pay for your own AI tool. Either way, changes show up as visual, editable elements you can inspect or adjust yourself, with no code to review.
Visual customizations
Lovable’s visual editing is limited to text. Anything beyond that, including layout, styling, and feature changes, goes through AI chat, sketch annotations on the preview, or custom code, and changes made through prompts use credits.
Replit’s visual editor covers direct UI, content, and layout edits, which goes further than Lovable’s text-only editing, though it’s narrower than Bubble’s. Those direct edits don’t use credits, but deeper logic, backend behavior, and complex customization still route through Agent or code.
Bubble’s visual editing covers the whole app, and you can change any part of it by hand. Drag the checkout button to exactly the spot you want it, add a step to your checkout workflow that emails customers a receipt, add a shipping address field to your orders, and set a privacy rule so customers only see their own orders. None of those changes use AI credits.
Manual coding
Replit fits best if you’re looking to customize your app manually with traditional code. Replit exposes the code Agent is writing within the development environment, so you can edit the code directly and make your app look and function exactly as you want it to.
Lovable also offers an in-platform code editor, but it’s only available on paid plans (Pro and above). On any plan, you can sync the code to GitHub and edit it there.
Bubble lets you add custom code for any element or feature. If you want to, you can drop HTML, CSS, or JavaScript into an HTML element, run JavaScript from a workflow action, or build a custom plugin. Custom code is optional, though, since the design, data, and logic are all built visually.
Iteration and debugging
Every app breaks sometimes, whether AI built it or not. What differs across these platforms is how you find out what went wrong and who does the fixing.
Lovable can check its own work. It writes tests for logic changes, can click through your app in a browser while watching for errors, and lets you revert to an earlier version if a change breaks something. When a bug is in the logic or backend, though, the fix goes through another prompt or the code editor, so if you don’t read code, you’re counting on the AI to diagnose its own mistake.
Replit Agent checks its own work too, and if your app crashes, it can read the error and fix the bug on its own. It saves checkpoints as it works, so you can roll back a change that breaks something, and you can restore the database to an earlier checkpoint. Fixes are billed by effort, so a bug that takes several attempts costs more, and if you don’t read code, you’re relying on Agent’s summary to know what it changed.
Both approaches lean on AI checking its own work, which has limits. A December 2025 study found that AI models’ debugging ability drops 60–80% after just two or three attempts.
On Bubble, the Agent also checks its own work. As it builds, it uses the issue checker to catch problems like missing data sources or invalid actions in workflows, and fixes what it finds. The difference is what happens when the AI misses something: The logic reads as plain-language steps, so you can open the workflow, see where it goes wrong, and fix it yourself. The Agent can also help you debug:
- Plain-language explanations: Ask why something was built a certain way, and the Agent walks you through its logic in plain English.
- Missing workflows: The Agent can find buttons that don’t have workflows yet, before your users click them and nothing happens.
- Issue checker fixes: Point the Agent at any issue the issue checker flags, and it can fix supported issues for you.
- Backend workflows: Ask the Agent to explain or fix a backend workflow, the logic that runs behind the scenes, like processing data in bulk or sending a reminder every Monday.
If you turn it on in your app’s settings, the Agent can use your app’s sample data to track down data problems. When a change doesn’t work out, built-in version control lets you roll back to an earlier version with one click.
Design functionality
How your app looks is the first thing users notice, and these three platforms give you very different amounts of control over it.
Lovable’s generated designs are responsive automatically and tend to look polished with very little prompting. To steer the look, you can share screenshots in the chat or bring in designs from Figma through its Figma plugin, a Figma MCP connection, or a .fig file upload, and paid plans add design systems you can reuse across projects. By hand, you can edit text inline, and other design changes, like colors, layout, and spacing, go through a prompt or the code.
Replit’s layouts adjust across desktop and mobile browsers. Replit Design is an infinite canvas where Agent generates design frames you can sketch on and annotate before building them into your app, and you can give Agent a screenshot or a Figma frame to work from. By hand, the visual editor lets you click an element to change its text, colors, or layout, while bigger structural changes still go through Agent.
On Bubble, the Agent builds responsive layouts by default and uses your app’s style variables, so pages look clean from the first prompt. You can show the Agent what you want by uploading a screenshot or Figma file, or by sharing one through the Bubble MCP. By hand, you design in a drag-and-drop editor down to the pixel, set your own breakpoints when you want more control, and keep colors and fonts consistent with a reusable design system.
Backend and database
Your database holds everything your app knows about its users, so you need to be able to see how it’s set up and who can access it.
Lovable Cloud, built on Supabase, handles your database, authentication, storage, and edge functions, or you can connect your own Supabase project. In the Database view, you can browse tables and edit records directly, and a read-only view lists each access rule, but schema and rule changes go through chat or an SQL editor.
Replit sets up a built-in PostgreSQL database and Replit Auth automatically, and it creates a production database for you when you publish. Because Replit generates code, your database schema and access rules live in that code, so changing them means prompting Agent or editing the code.
Bubble includes a built-in visual database. You can ask the Agent to generate your entire database and schema from a prompt, complete with sample data, and every time it creates a data type (a kind of record your app stores, like users or orders), it creates privacy rules for it automatically. Because those privacy rules are visual, you decide who sees what in your app, down to each field, without reading code. You can also run bulk data actions to update many records at once as your user base grows.
Native mobile app support
Native mobile apps do things a web app can’t, like push notifications, camera access, and a listing in the app stores. They’re even more useful when your mobile app shares a backend with your web app, so data, users, and workflows all stay in sync.
Lovable builds responsive web apps that work in mobile browsers, but it doesn’t build native iOS or Android apps. There’s no built-in flow for submitting to the app stores, so getting a Lovable app listed means packaging it as a progressive web app or with a wrapper like Capacitor.
Replit builds mobile apps with Expo and React Native. You prompt Agent like you would for web and preview the app on your phone, and when you’re ready for iOS, Replit and Expo build it in the cloud, so you don’t need a Mac or Xcode. Replit can build and preview Android apps but doesn’t publish to the Google Play Store yet (as of Oct. 28, 2026), and mobile apps are customized mostly through code or prompts.
With Bubble for native mobile apps, you build iOS and Android apps in the same visual editor as your web app, sharing one backend, database, and set of workflows. You can describe a mobile app to the Agent or build one from scratch in the visual editor. With native mobile app generation (beta), the Agent builds iOS and Android apps from a prompt. Either way, you get full control over native device features like the camera and push notifications, mobile gestures, and other mobile-specific design elements, all without writing code.
You can preview your app in the browser with the Simulated device option, or on a real device with dev builds once you’re on a paid plan. On a Mobile or Web & Mobile plan, you can publish to the App Store and Google Play Store straight from the Bubble editor. Bubble also supports over-the-air (OTA) updates for shipping changes to your published app, and in-app purchases (beta), currently for subscriptions only.
Security
Once customers or your team rely on your app, security isn’t optional. It depends on two layers: how secure the platform is, and how secure the app you build on top of it is.
It’s worth knowing upfront how much of that security comes built in and what you’ll need to set up yourself.
Lovable is SOC 2 Type II compliant and ISO 27001:2022 certified. A Quick Scan runs every time you publish and checks your data access rules and dependencies, an on-demand Deep Scan reviews your app’s code for issues like leaked secrets, and Business plans add a workspace security center. Lovable sets up basic row-level security policies automatically, but reviewing your app’s data access rules is still on you, and those rules live in code.
Replit is SOC 2 Type II compliant and hosts data primarily on Google Cloud. Its Project Security Center includes Agent security scans on paid plans, automatic dependency scans, and a check at publish that can block critical issues, and Enterprise plans add SSO. As on Lovable, reviewing who can access which data is still on you.
Bubble is SOC 2 Type II compliant, and its privacy rules support GDPR compliance. The Agent generates privacy rules automatically when it creates new data types, and you can fine-tune those rules yourself in the visual editor, with no code required.
On paid plans, a built-in security dashboard scans for things like leaked API keys and unsafe configurations, then walks you through fixing them in the editor. Organizations on the Enterprise plan can use SSO to log in to Bubble, and you can add SSO login for your app’s end-users through the WorkOS plugin or the API Connector. You don’t need to be a security expert to get started, but you’re still responsible for reviewing your app’s structure and settings before you launch.
Deployment and hosting
Built-in deployment and hosting get your app in front of users without setting up servers yourself.
Lovable, Replit, and Bubble all offer one-click deployment from the editor. The bigger differences show up in hosting.
Lovable hosts your app and scales it automatically, with SSL on every plan and custom domains on paid plans. A live site doesn’t use credits on its own, but Cloud usage and built-in AI do, and apps that rely on them can pause when credits run out. If you’d rather host elsewhere, you can sync your code to GitHub, or download it on a paid plan, and deploy to hosts like Vercel, Netlify, or Cloudflare Pages.
Replit hosts your app too, with four deployment types to choose from: Static, Autoscale, Scheduled, and Reserved VM. They’re useful if you want control over how your app runs, though they add decisions to make if you just want your app online. Apps in personal workspaces publish publicly by default, and deployments draw from the same credits as Agent usage. Because you have full access to the code, you can also download it as a zip or sync it to GitHub and host it yourself.
On Bubble, paid plans include built-in hosting on managed infrastructure with auto-scaling, a global CDN, automatic backups, and one-click rollback. Because your app, database, and hosting live on one platform, you have fewer tools to juggle each time you ship an update, and the app you launch is the app you keep growing. Organizations on the Enterprise plan can access advanced infrastructure and security options.
Bubble apps run on Bubble’s hosting, but you’re not locked in. If you ever need your app in code, you can export it with the Bubble MCP, which lets an AI agent like Claude Code or Codex rebuild it in code you own and host, and your data comes with you through the MCP or a CSV or JSON export. Keep in mind that a rebuild gives you a new stack to host, secure, and maintain yourself.
Pricing and AI credits
Lovable’s Free plan gives you five build credits a day, up to 30 a month, and paid plans include 100 credits a month. Since June 2026, building, Cloud usage, and built-in AI draw from one credit balance, so when you run out, building stops until your credits refresh or you buy more.
Replit’s free Starter plan includes a daily Agent allowance and one published app. Paid plans include monthly credits that cover Agent usage, deployments, and storage. Free Mode handles everyday Agent changes within an allowance that resets every five hours, and bigger jobs are billed by effort, so a stretch of complex debugging can use credits faster than you expect.
Getting started on Bubble is free. You can build and test on the Free plan, and you’ll need a paid plan to launch a web app or connect a custom domain, or a Mobile or Web & Mobile plan to publish to the app stores. Every plan includes a monthly AI credit allowance, but you never depend on AI credits to build your app: Generating an app with the Agent, including the planning session, doesn’t use them, and neither does working in the visual editor or the Bubble MCP. Building and editing with the Agent does.
If you run out mid-request, the Agent keeps the work it finished and tells you what’s left, and nothing is charged automatically. Paid plans can buy more credits anytime. Once your app is live, its server work is measured in workload units, which are separate from AI credits.
Here’s how the three compare:
| Pricing | Lovable | Replit | Bubble |
|---|---|---|---|
| Free plan | Build with five credits a day (up to 30 a month). | Build with a daily Agent allowance and publish one app. | Build and test with a monthly AI credit allowance. Launching needs a paid plan. |
| Paid plans start at | $25/month, or $21/month billed annually | $18/month billed annually or $20/month billed monthly for Core | $32/month billed annually or $39/month billed monthly for web |
| AI credits | Building, chatting, Cloud usage, and built-in AI share one credit balance. | Monthly credits cover Agent work, deployments, and storage. Free Mode covers everyday Agent changes within an allowance. | A monthly allowance covers building and editing with the Agent. Generating an app doesn’t use AI credits. |
| Visual changes | Inline text edits don’t use credits up to a daily limit. Other visual changes go through prompts that use credits. | Clicking an element to change its text, colors, or layout doesn’t use credits. Bigger structural changes go through Agent. | No change you make by hand, from layout to workflows and data, uses AI credits. |
| Hosting | Built-in hosting with SSL on every plan, and custom domains on paid plans. | Built-in hosting with four deployment types to choose from. | Built-in hosting on paid plans, with auto-scaling and a global CDN. |
Collaboration
AI makes it possible to build an app on your own, but most businesses eventually bring in a teammate, a contractor, or an agency. When that happens, it helps to know how many people can work on the app, whether they can edit at the same time, and what each person can access.
Lovable supports real-time collaboration, even on the Free plan. Each collaborator can work in their own draft, changes reach the main project only after someone accepts them, and collaborators use credits from the project owner’s workspace. Because every change is a code change, teams typically review it as code diffs, in Lovable’s version history or in GitHub.
Replit supports real-time co-editing with cursor presence, workspace roles (Member, Guest, and Viewer), and GitHub integration. Its old Teams plan is retired, so teams now pick Core, Pro ($90/month billed annually or $100/month billed monthly, for up to 15 collaborators plus 50 viewers), or Enterprise.
Bubble supports real-time editing, and you can control each collaborator’s access down to specific areas of your app, like the database or logs. Teammates work from logic they can read, so anyone joining a project can follow what the app does. Bubble’s Team plan runs $399/month, or $349/month billed annually, and includes hosting and a database.
Here’s how they compare side by side:
| Lovable | Replit | Bubble | |
|---|---|---|---|
| Unlimited collaborators on each app | ✅ Invite your whole workspace, even on the Free plan | Up to 15 collaborators plus 50 viewers on Pro | Depends on your plan |
| Choose which apps collaborators can access | ✅ | ✅ | ✅ |
| Set access permissions for each user | Roles like Viewer, Editor, and Admin on paid plans | Workspace roles (Member, Guest, and Viewer) | ✅ |
| Collaborate in real time | ✅ | ✅ | ✅ |
| Team plans available | Team features included in higher tiers | ✅ | ✅ |
| Version control available | Version history and two-way GitHub sync | ✅ | ✅ |
Integrations
Plugins and integrations let you connect other tools to your app instead of building everything from scratch. When you’re comparing platforms, it’s worth looking at:
- How big and useful the integrations library is: A larger library means the payment, AI, and productivity tools your app needs are more likely to be ready to connect.
- How much setup the integrations take: Some connect in a few clicks, while others need API keys, configuration, or code, which can slow you down if you don’t write code.
- Who’s responsible for keeping them updated: When a connected service changes its API, someone has to update the integration, and it’s better to know upfront whether that’s you.
Beyond GitHub and its Supabase-based backend, Lovable connects to services like Slack, Google Sheets, Notion, Linear, Gmail, and Salesforce through its connectors, and built-in payments run through Stripe or Paddle on paid plans. Lovable also has its own MCP server on every plan, so you can create projects, send build requests, and deploy from the AI tool of your choice.
Replit’s integrations grew after it acquired OpenInt in September 2025 as the foundation for Connectors, which link your app to services like Google Workspace, Microsoft 365, GitHub, Slack, Stripe, and Shopify. Replit groups its integrations into four categories: Replit-managed integrations (like its database, auth, and App Storage), Connectors, external integrations, and Agent services.
Bubble has a large plugin ecosystem, and the Agent can install and uninstall plugins for you. Options include:
- OpenAI and ChatGPT: Add AI text generation and chat to features like support assistants, content tools, or document summaries.
- Anthropic’s Claude: Call Claude models from your app’s workflows for tasks like drafting replies or analyzing long documents.
- Stripe: Accept one-time payments and subscriptions, which most marketplaces and SaaS apps need before launch.
- Google Suite products: Connect services like Google Sheets, Maps, and Calendar to sync data, show locations, or schedule events.
- Many more: Browse the Bubble Marketplace for plugins across categories like analytics, messaging, and file storage.
Plugins connect to your app’s workflows and usually need little setup.
If an integration isn’t available as a plugin, you can often connect to the service directly using Bubble’s API Connector, and the Agent can set up those calls for you. The API Connector automatically parses API responses into fields your app can use, so you don’t have to map them by hand. Experienced developers can also build custom plugins.
Here’s how these three platforms stack up:
| Feature | Lovable | Replit | Bubble |
|---|---|---|---|
| Integration library | Connectors plus its own MCP server | Connectors for services like Google Workspace, Microsoft 365, Slack, and Stripe | ✅ Large plugin library plus the API Connector |
| Setup without code | ✅ | ✅ | ✅ The Agent can install plugins and set up API Connector calls |
Learning curve and technical expertise
Even though AI builds much of the app, every platform still takes some learning to get from first draft to launch.
Lovable is the quickest to pick up at first, but that early momentum comes with a tradeoff. Because the logic lives in code, you get less visibility into how your app works, and later changes tend to get harder as the app grows. Complex logic often means learning more, editing code, or spending credits on more prompts.
Replit is approachable to start. You can describe your app to Agent, plan it out in Plan mode, and get a database, auth, and hosting set up automatically. The learning curve shows up later, when you need to change the logic or fix a bug, because that means reading the code Agent wrote or trusting another prompt.
If you’re comfortable with code, or you’ve outgrown a tool like Lovable and want to learn, Replit gives you a solid place to work on code with AI help, and its support for iterating on and managing code holds up.
Bubble has a learning curve too. The Agent gets you started and explains what it builds in plain language, but learning the visual editor well enough to build complex apps takes time. We think that time is well spent. Once you understand how your app’s workflows, data, and privacy rules fit together, you can change any part of it yourself, the day you have the idea, and keep improving it long after the first draft.
Between Bubble Academy, technical documentation, the Bubble Forum, and a YouTube channel, there’s support for every skill level. If you’d rather have someone build the app for you, a Bubble Expert or professional Bubble Developer can take it on.
Which AI builder is right for you?
Lovable, Replit, and Bubble each fit a different kind of builder, and the right one depends on what you’ll need to do with the app after the first version.
Choose Lovable if you want a design-forward prototype, landing page, or MVP and don’t mind touching code for deeper changes. Visual editing covers text only, and other simple changes work well through AI chat, even if you don’t write code. Complex functionality still takes some technical know-how.
Choose Replit if you want AI to build and set up a full-stack app for you and don’t mind that the app is code underneath. Agent handles the database, auth, and hosting, you can edit the code yourself or through Agent, and reading code helps when you need to change the logic. You get more backend functionality out of the box than Lovable offers.
Choose Bubble if you’re building a business on your app and want to understand, change, and grow it yourself without writing code. On Bubble, the design, data, and logic stay visual from your first planning session through launch and every change after it.
Bubble also fits teams building internal tools who don’t want to wait on engineering for every change. Because the logic is visual, the people who use a tool every day can follow how it works and update it themselves.
For agencies handing apps off to clients, Bubble gives clients an app they can understand and keep running after the handoff, and anyone on your team can pick up a project midstream.
If you already have an app in Lovable or Replit, you don’t have to start over. With universal import, you can bring it into Bubble as a .zip or .html file, or through the Bubble MCP, and Bubble generates a new, fully visual app that you keep building with the Agent or by hand.
Build your next app with the right tool
AI can get you to a first version on any of these platforms. Most of your time goes into what comes after: securing your data, bringing on a team, and changing the app as customers ask for new things.
On Bubble, every layer of your app stays visual and editable. When your business changes, you can change the app yourself and know exactly what you changed. Businesses already run on it, with Bubble apps transacting more than $1 billion a year.
Get started for free and describe the app you plan to run. Generating it with the Agent doesn’t use AI credits.
Frequently asked questions about Lovable, Replit, and Bubble
Can I move an app from Lovable or Replit to Bubble?
Yes. With universal import, you can bring an app built with an AI coding tool like Lovable or Replit into Bubble by uploading a .zip or .html file, or through the Bubble MCP (beta). Bubble generates a new, fully visual app from it, and you keep building with the Bubble AI Agent or in the visual editor.
Can I export my Bubble app if I need it in code later?
Yes, you own your app’s design and data, and you can export the app with the Bubble MCP (beta), which lets an AI agent like Claude Code or Codex rebuild it in code you own and host. Your data moves through the MCP or a CSV or JSON export, and unlike Lovable and Replit, which give you their generated code directly, exporting from Bubble is a rebuild.
Can I build on Bubble from Claude, Codex, or ChatGPT?
Yes, the Bubble MCP (beta) connects your Bubble app to AI tools like Claude, Codex, or ChatGPT, letting you build from a tool you already use. Everything you build that way lives in your Bubble app, where you can review and adjust it in the visual editor.
Can I run a business on a Bubble app?
Yes. Bubble apps transact more than $1 billion a year, Bubble is SOC 2 Type II compliant, and paid plans include built-in hosting with auto-scaling as your user base grows.
Which is best for non-technical founders: Lovable, Replit, or Bubble?
Bubble fits non-technical founders who plan to keep changing their app, because the design, data, logic, and privacy rules stay visual and editable without code. Lovable works well for design-forward prototypes, and Replit fits builders who want a full-stack app set up for them and don’t mind working with code when they change the logic.
Can Lovable, Replit, or Bubble build native mobile apps?
Replit generates React Native apps through Expo and publishes to the App Store but not yet to the Google Play Store, while Lovable focuses on web apps and needs a third-party wrapper for app store distribution. Bubble builds native iOS and Android apps in the same visual editor as your web app and publishes to both stores.
How much do Lovable, Replit, and Bubble cost?
Lovable’s paid plans start at $25/month ($21/month billed annually), Replit’s Core plan starts at $18/month billed annually ($20/month billed monthly), and Bubble’s paid web plans start at $32/month billed annually or $39/month billed monthly. All three offer a free way to get started.
What are the downsides of building on Bubble?
Visual programming has a learning curve, though the Bubble AI Agent explains what it builds in plain language and Bubble Academy covers the basics. Bubble apps also run on Bubble’s hosting, so if you want code you can edit in your own tools from the start, a code-based tool like Replit or Lovable fits better, since moving a Bubble app to code means having an AI agent rebuild it through the Bubble MCP (beta).
