There’s a better way!

Introducing Anvil - the simplest way to build web apps with Python

Django is a great way to build the server side of your web app, but to build powerful fullstack web apps, you’ll also need to know:

  • HTML
  • CSS
  • JavaScript
  • Web hosting
  • SQL / ORM

With Anvil, you can:

  • build your UI with drag-and-drop (no HTML or CSS)
  • run Python in the browser (no JavaScript!)
  • run Python on the server (full CPython server environment)
  • deploy your apps with one click (no need to wrangle with Google Cloud, Digital Ocean, Heroku, Docker, or AWS)
  • use the built-in PostgreSQL database, and query it from Python!
Try Anvil - it's free!

Build your UI with drag and drop

Note: This guide includes screenshots of the Classic Editor. Since we created this guide, we've released the new Anvil Editor, which is more powerful and easier to use.

All the code in this guide will work, but the Anvil Editor will look a little different to the screenshots you see here!


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

See an example

Run Python in the browser

Modify your UI components with Python running in the browser

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

See an example

Run Python on the server

Use simple Python function calls to pass information from the server to client

No need to set up routing or endpoints, just write your server-side Python functions and call them from your client side code.

Built-in database

Anvil has a full database system built on top of PostgreSQL

Query or edit your data with a no-nonsense Python statement.

Or use your own database - it’s just Python.
