Build Python web apps that run in the browser

Introducing Anvil

  • build your UI with drag-and-drop (no HTML or CSS)
  • program your UI with client-side Python (compiled to Javascript!)

You can build the rest of your app in Python too.

Anvil is a platform for building fullstack Python web apps:

Run Python in the browser

Modify your UI components with Python running in the browser

UI components are represented in code as Python objects.

When components raise events, they call Python functions in your client-side code.

Build your UI with drag and drop

No HTML, CSS or JavaScript! (unless you want to use them!)
