nxv

CLI, API, and web UI to find any historical version of any Nix package

Webfreeglobal

nxv is a search tool for the Nix package ecosystem that indexes nearly a decade of nixpkgs channel-release history, letting developers find when a package version was introduced and the exact commit to pin it with `nix shell`. It's available as a CLI, an HTTP API with web UI, or a self-hosted NixOS module, aimed at developers who need historical or legacy package versions.
