## What it is
PyScript is an open source platform for running Python directly in the browser, built on Pyodide (CPython), MicroPython, and WebAssembly. It lets developers embed Python code in HTML pages via script tags, creating rich client-side applications that run anywhere a browser runs.

## Use cases
- run python in the browser without a server
- embed python code in html pages
- build client-side web apps in python
- share python apps as a simple url
- run python on mobile and tablet via browser
- teach python with zero installation

## When to choose
- you want serverless python web apps that run entirely client-side
- you need python to run on any device with a browser
- you want to mix python with html and javascript in one page
- you want zero-install python for education or demos

## When to avoid
- you need a maintained project - PyScript has entered maintenance mode
- you need heavy server-side python frameworks like Django or Flask
- you need native performance or access to native OS APIs
- your app requires large python dependencies not supported by Pyodide

## Facets
- artifact type: framework
- maturity: maintenance
- function: wasm, interpreter, frontend-framework, developer-tools
- domain: web-development, frontend, programming-languages, cross-platform
- platform: browser, wasm, cross-platform
- tags: pyodide, micropython, python-in-browser, html-embedding, client-side-python, web-server
