Detect Nix in any GitHub repo

Nix is one of the runtime technologies Stack Fingerprint recognises automatically when it scans a public repository.

How Nix is detected

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

  • Files or folders: flake.nix, shell.nix, default.nix

Nix README badge

A static badge you can paste anywhere in Markdown:

Nix badge

Markdown
![Nix](https://img.shields.io/badge/Nix-5277C3?style=for-the-badge&logo=nixos&logoColor=white)

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 Nix (and everything around it) appears or disappears on its own:

[![Stack Fingerprint](https://stackfingerprint.vercel.app/api/card?repo=OWNER/REPO)](https://stackfingerprint.vercel.app/?repo=OWNER/REPO)

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