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
