How to Build a Multi-Tenant SaaS App With No Code

TL;DR: A multi-tenant SaaS app serves many customer organizations from one shared app and database, and each organization sees only its own data because every record links to an organization. To build one, add that organization link before anything else, enforce separation with database-level privacy rules rather than page filters, scope roles, invites, and Stripe billing to each organization, and run a two-tenant leak test before you launch.

When your company signs up for Slack or Notion, it gets a workspace of its own. Thousands of other companies use the same app at the same time, and none of them can see into yours. That's multi-tenancy, and you probably use it every day.

It's a great setup because you only build and maintain one app, and every fix reaches every customer at once. The catch is that one bad access rule can leak a customer's data to another, and access control failures top the OWASP Foundation's 2025 list of web app security risks.

This guide covers the core features of a multi-tenant SaaS app and the workflows behind them, so you can build your own version or borrow the parts you need. You'll set up organizations and roles, keep each tenant's data separate, and add invites and billing, then test everything before you launch your MVP. You can build it all with the Bubble AI Agent or by hand, and change any part as you go.

What is multi-tenant SaaS architecture?

Multi-tenant SaaS runs on a multi-tenant architecture, where one app and its infrastructure serve many customers, called tenants. Tenants share the same code, servers, and usually the same database, but each one sees only its own data. Isolation works because every record carries a tenant identifier, such as a link to an organization, and every access check uses that identifier.

This guide uses a shared database with a tenant field. Every record a tenant owns points to an organization, and every list, search, and privacy rule checks that link. It's one of three common tenancy models:

Single-tenant setups give each customer their own copy of the app and infrastructure. Isolation is stronger, but you pay for and maintain every copy, while multi-tenant SaaS lets one app serve them all.

The rest of this guide builds the shared-database model, starting with how you want to build it.

Two ways to build it on Bubble

You can generate this app with the Bubble AI Agent, or build every piece by hand. Building by hand takes longer, but you'll learn how tenancy works on Bubble and know exactly what each privacy rule does. The Agent writes privacy rules for every data type it creates, but you'll still want to spend some time double-checking them.

Knowing how your app works pays off once customers depend on it. Upfront, a GovTech platform that serves five states, customizes its Bubble app for each one, and its product manager answers most questions himself:

"I love being a product manager working on a Bubble app because I have answers to 90% of the questions myself," says Younès Atmani, product manager at Upfront.

To use the Agent, describe what you want, for example: "Build a B2B SaaS where each customer organization has its own workspace, owner, admin, and member roles, organization-owned projects, email invites, and a subscription per organization."

The Agent starts with a planning session and asks clarifying questions, like whether one person can belong to several organizations. You can tweak the plan or skip straight to generating, which doesn't use AI credits (up to a monthly limit).

It then builds the pages, database, workflows (the step-by-step logic behind each action), and privacy rules. Open the data tab and check that every data type a tenant owns has an organization field and privacy rules that use it, then fix anything that's off by hand or with the Agent.

If you're new to Bubble, Bubble Academy covers the basics, and our SaaS development guide covers planning a subscription product.

Whichever route you take, the steps below describe the same structure, so you can follow them by hand or use them as a checklist for what the Agent built.

Step 1: Set up your multi-tenant database

Set up your database before you design any pages. Adding a tenant link to data you've already created is a lot harder than building it in from the start, and every page you design later depends on that link. For more on planning the structure, see our guide to SaaS database design.

Your database holds everything your app keeps track of. On Bubble, each kind of record is a data type, each detail on it is a field, and each individual record is a thing. Option sets are fixed lists you keep in one place, like a list of roles.

Create these data types in the data tab:

Data type: User

Fields:

• Name (text)
• Memberships (list of Memberships)
• Current organization (Organization) - Note: This field tracks which workspace the user has open right now

Data type: Organization

Fields:

• Name (text)
• Logo (image)
• Brand color (text)
• Owner (User)
• Plan (Plan option set)
• Subscription ID (text)
• Subscription status (text)
• Seat limit (number)

Data type: Membership

Fields:

• User (User)
• Organization (Organization)
• Role (Role option set)
• Status (Membership status option set) - Note: A separate Membership data type lets one person belong to several organizations, with a different role in each

Data type: Invitation

Fields:

• Email (text)
• Organization (Organization)
• Role (Role option set)
• Invited by (User)
• Accepted (yes/no)

Data type: Project

Fields:

• Name (text)
• Description (text)
• Organization (Organization)
• Created by (User)

Option sets: Role (owner, admin, member), Plan, and Membership status (invited, active, removed)

With the data model in place, you can build the workflows that put each person in the right organization.

Step 2: Build signup, invites, and roles

Workflows are the logic behind your app: Each one runs actions (like creating a record) when an event happens (like a user clicking a button). In a multi-tenant app, every workflow should keep work inside a single organization.

• Organization signup: When a new customer signs up, create an Organization and a Membership that makes them its owner, so every account belongs to a tenant from its first record.
• Team invites: Let owners and admins invite teammates by email with an Invitation. When someone accepts, create a Membership in that organization only and mark the invitation accepted.
• Roles: Use the membership role to decide who can manage billing, invite people, or just work on projects. Conditionals (rules that show or hide elements based on the current user) keep actions a role can't use out of view.
• Organization switching: If someone belongs to several organizations, let them pick which workspace to open and save it in their Current organization field.
• Tenant-scoped lists: Filter every repeating group (Bubble's element for displaying lists) by the current organization, so each page only asks for data the user should see.
• Tenant branding: Pull each organization's logo and brand color into its workspace, so customers see their own brand inside your shared product.

Conditionals only change what people see, so Step 4 adds the privacy rules that protect the data itself. Our guide to building a project management app goes deeper on role-based permissions.

Once people can join and work inside an organization, the next step is charging each one.

Step 3: Add per-tenant billing with Stripe

Bill each organization, not each person. Bubble's Stripe plugin subscribes a user to a plan, so a common setup is to have each organization's owner hold the subscription, then save its subscription ID and status on the Organization record. If you'd rather give each organization its own Stripe customer, you can create one through Stripe's API with the API Connector.

Stripe can send webhook events when a subscription changes, and a backend workflow can catch them and update the organization's status, so your app always knows what each organization pays for. Our Stripe integration guide walks through the setup.

To enforce plan limits, compare an organization's active memberships against its seat limit before sending a new invite. The same check can show an upgrade prompt when a team runs out of seats.

With people and payments in place, the most important step is making sure no organization can see another's data.

Step 4: Set privacy rules and test tenant data isolation

Bubble provides the database, hosting, encryption, and privacy rules for your multi-tenant SaaS app. You decide which organization's members can see and change each record, then configure those rules and test them.

Privacy rules are Bubble's form of row-level security, controlling who can see and change each data type and field. They're what keeps one tenant's data away from another, while filtering a list on a page only hides data from the screen. Set privacy rules for every data type:

Write each rule around the user's active membership in the organization. The Current organization field on the User data type only tracks which workspace someone is viewing, so a rule that checks it can't tell whether that person belongs there.

If the Agent built your app, treat its privacy rules as a first draft. Check each one against the table above and adjust it yourself or with the Agent.

Next, run a two-tenant leak test. You'll log in as users from two separate organizations and confirm neither can reach the other's data:

1. Create two test organizations, each with its own users.
2. Log in as a member of the first organization, and check that no data from the second appears in lists, searches, or page links.
3. Open a page using a record ID from the other organization, and confirm that the privacy rules return nothing.
4. Log in as a member-level user, and check that they can't reach admin-only actions.

Before you deploy, the security dashboard (available on paid plans) checks your app for common security risks. The Starter plan runs basic checks, like missing privacy rules and exposed credentials. Growth, Team, and Enterprise plans add advanced checks for compromised API tokens, database exposure, and unprotected backend workflows.

For more detail, see Protecting data with privacy rules in the Bubble Manual and our guide to customer data privacy. Once your leak test passes, you're ready to launch.

Step 5: Launch and keep growing

Deploying takes one click, and paid plans include hosting and auto-scaling. You don't have to set up a scalable SaaS architecture yourself, and your hundredth customer uses the same app as your first. Bubble's platform is also SOC 2 Type II compliant, which helps when a customer's security review asks how their data is protected.

Paying developers to build tenant isolation, roles, and billing from scratch adds up fast. On Bubble, getting started is free, though apps on the Free plan can't go live. Paid web plans start at $32/month billed annually, or $39/month billed monthly (see the pricing page for current plans).

Every plan includes a monthly AI credit allowance for building with the Agent, and working in the visual editor doesn't use AI credits. Some templates and plugins cost extra, and Stripe charges its own processing fees.

What to add next

Once your MVP works, you can get creative with the experiences you build. A few ideas:

• Audit log per organization: Record who changed what inside each workspace, so a customer's admin can review activity when something goes wrong.
• SSO for your customers: Add SSO login for end-users through the WorkOS plugin, which works with any identity provider that supports SAML or OIDC, or connect an SSO provider through the API Connector. Larger customers often ask for it before they sign.
• White-label SaaS for agencies: Extend tenant branding so each client sees its own logo and colors, and you can resell one product to many clients.
• Usage tracking and limits: Count actions per organization to support usage-based plans or upgrade prompts.
• Scheduled reminders: Use backend workflows (logic that runs on Bubble's servers instead of in the browser) to email organizations before a trial ends or after a payment fails. If you expose any workflows as an API, secure them with authentication, conditions, and privacy rules.
• An internal admin view: Build a page where you, the SaaS owner, can manage every organization (our dashboard guide covers layouts, filters, and per-client access). Give it its own privacy rules so tenant users can't reach it.

Start building your multi-tenant SaaS app

Bubble can help you build a multi-tenant SaaS app, or whatever product you have in mind, and keep improving it as your customer base grows. If you get stuck along the way, other builders on the Bubble Forum can help.

Every layer of your app is visual, including the privacy rules that keep each tenant's data separate, so you can see exactly how it works and change it yourself when a customer asks for something new. Hosting and scaling come included, so you keep growing on the same app instead of rebuilding it later.

Frequently asked questions

Can I build a multi-tenant SaaS app without writing code?

Yes, on a fully visual app builder like Bubble you can link every record to an organization and set visual privacy rules that keep each tenant's data separate. You'll still need to set up those rules and test them with users from two organizations.

What is the difference between a multi-tenant cloud and a multi-tenant SaaS app?

A multi-tenant cloud shares infrastructure, like servers, across many customers. A multi-tenant SaaS app shares one application across many customer organizations, and it usually runs on that kind of cloud.

When does a multi-tenant SaaS app need dedicated infrastructure?

Usually when an enterprise customer or a regulation calls for more isolation than shared infrastructure and privacy rules can give you. Bubble's Enterprise plan offers custom infrastructure and dedicated capacity for those cases.

Can a multi-tenant SaaS app built on Bubble run on web and native mobile?

Yes. With Bubble for native mobile apps, your iOS and Android apps share the same database, workflows, and privacy rules as your web app, so tenant isolation carries across every platform.
