A no-code app builder is a platform for building fully functional web and mobile applications without writing code. Instead of programming languages, you use visual tools to design your UI, define your data, and build your logic — then deploy a working app.
Bubble takes it further than most. Bubble is a visual programming language, not just a drag-and-drop interface. There's
no code generated or hidden underneath, so you never have to think in JavaScript, Python, or anything else.
