Detect FastAPI in any GitHub repo

FastAPI is a modern Python web framework for building APIs with type hints, automatic OpenAPI docs and async support.

Why show FastAPI on your README

Python projects hide their framework in requirements.txt or pyproject.toml; Stack Fingerprint reads both so FastAPI shows up without a hand-made badge.

How FastAPI is detected

Stack Fingerprint reads the repo's full file tree in one GitHub API call and flags FastAPI when it finds any of these:

  • Files or folders: main.py
  • Dependencies in Python (requirements.txt / pyproject.toml): fastapi, uvicorn, starlette

FastAPI README badge

A static badge you can paste anywhere in Markdown:

Or let the repo describe itself

Static badges go stale the moment you swap a dependency. A Stack Fingerprint card is generated from the repo, so FastAPI (and everything around it) appears or disappears on its own:

Replace OWNER/REPO with your repository, or open the builder to pick a theme and layout.
