A native app built with Tauri v1 that spawns a Python sub-process (sidecar) which starts a FastAPI server.

Tauri v2 example is now available 👇

More features and documentation with example app.exe.
This example app uses Next.js as the frontend and Python (FastAPI) as the backend. Tauri is a Rust framework that orchestrates the frontend and backend(s) into a native app experience.
Tauri takes your frontend UI written in html/javascript and displays it in a native webview. This makes the resulting file size smaller since it does not need to include a web browser.
