Any Nix package, live in your browser

Farid Zakaria launched trynix.dev, a browser-based Nix package runner. It boots a Linux VM in a browser tab, giving users a shell with any of over 310,083 historical Nix package versions on PATH. Users can search, select a version, and run it without installing anything locally. The service also supports booting store paths from custom caches, including GitHub Pages.

Developers can now run any historical Nix package in a browser without local installation, simplifying testing and sharing.
