Flexx is a pure Python GUI toolkit that uses web technology (HTML5/JavaScript) for rendering, transpiling Python to JavaScript via PScript. It can build cross-platform desktop apps, web apps, standalone HTML documents, and works in Jupyter notebooks.
Use cases
- write desktop apps in pure python
- build web apps without writing javascript
- create interactive scientific dashboards in python
- export a python app to a standalone html file
- run python guis inside jupyter notebooks
- mix server-side and browser-side python code
When to choose
- you want a pure-Python GUI toolkit with no JavaScript required
- you need one codebase to target desktop, web, and standalone HTML
- you work in scientific/Jupyter contexts and want interactive UIs
When to avoid
- you need a large ecosystem of native widgets or mobile support
- you require a framework with heavy active development and large community
- you need fine-grained control over modern frontend tooling like React or Vue
