Quickly build web UIs in Python

Used at Google for rapid internal app development

Mesop is a Python-based UI framework that allows you to rapidly build web apps like demos and internal apps:

Easy to get started

• Write UI in idiomatic Python code
• Skip the FE learning curve.
• Ready to use components (e.g. chat)

Fast iteration

• Hot reload so the browser automatically reloads and preserves state
• Rich IDE support with strong type safety

Flexible & composable

• Build custom UIs without writing Javascript/CSS/HTML
• Compose your UI into components, which are just Python functions

See what you can build in less than 10 lines of code...

Check out how the above demo gallery was built in pure Mesop!
