PYLAGE PLAYGROUND

Build the interface in Python.

Write PyLage code, run it, and see the resulting UI directly in the browser.

Ready

Python first

Build interfaces using familiar Python APIs instead of switching between multiple UI layers.

Reactive by design

Use PyLage State and existing component mutation APIs to create interactive experiences.

Runs in the browser

The playground executes Python through the browser runtime and renders the resulting PyLage component.

One simple workflow

Write Python → run it → inspect the rendered component → iterate.

01 Write

02 Run

03 See

04 Iterate

PyLage

Python-native UI, from component to browser.
