## What it is
pywebview is a lightweight Python library that wraps native webview components to build desktop GUIs with HTML, JavaScript, and CSS. It provides two-way JavaScript-Python communication, a built-in HTTP server, DOM manipulation from Python, and window management across Windows, macOS, Linux, and Android.

## Use cases
- build a desktop gui for a python app using html and javascript
- create a cross-platform desktop application with web technologies
- wrap a web frontend in a native window without bundling a browser
- communicate between javascript frontend and python backend without rest
- make a lightweight alternative to electron for python
- package a python web ui into a distributable desktop executable

## When to choose
- you know web technologies and want a native-feeling python desktop app
- you want small executables instead of bundling electron or a heavy gui toolkit
- you need cross-platform support including linux gtk/qt and android
- you want direct js-python bridging without an http api

## When to avoid
- you need deep native widget sets beyond menus and dialogs - use Qt or native toolkits
- you need a full embedded browser with extensions or multi-tab browsing
- your app is purely web-deployed and doesn't need a desktop shell
- you require pixel-perfect identical rendering across platforms - web engines differ per OS

## Facets
- artifact type: library
