Pyxle

Pyxle is an open-source Python framework that combines Python and React in a single .pyxl file. It is built for applications where the async loader, server actions, and the React component using them live together, so the same feature can be read in one place rather than spread across several files.

The framework includes server-rendered output with hydration and hot reloading, and its browser playground runs real .pyxl code in sandboxed CPython. The documentation also describes file-based routing with files placed in pages/, server actions using @action in place of a separate API layer, and plugins for authentication, databases, and custom extensions. One example shown in the docs uses pyxle/client with useAction to call server actions from React components. The page also mentions a CLI check command, shown as pyxle check, for validating .pyxl files.

Pyxle runs on standard ASGI underneath and states that it has no special deploy story. The install command shown is pip install pyxle-framework, and the page lists Python 3.10+, Node, and any ASGI host as the runtime requirements. It is distributed under the MIT license, and the site links to a playground, plugins, benchmarks, and a roadmap. The framework is described as full-stack and as an approach for building features in one file rather than assembling a separate route handler, validator, types file, client hook, fetch wrapper, skeleton, component, and page.
