Redoc in Python

One file, no framework: http.server from the standard library answers every request with the docs page. The Redoc bundle comes from the jsDelivr CDN and the API description from a URL.

Run

python3 server.py

Then open http://localhost:8080.

Use it in your app

• server.py — the response is a <redoc spec-url> tag plus one script tag. That is all Redoc needs; in a real app the same HTML goes into whatever framework you use (Flask, Django, FastAPI).
• REDOC_URL (environment variable) overrides where the bundle is loaded from, for self-hosting or pinning another version.
• CAFE is where your API description lives — any URL the browser can fetch.

Docker

docker build -f docker/Dockerfile -t redoc-python .
docker run --rm -p 8080:8080 redoc-python
