Any Nix package, live in the browser

TryNix.dev allows users to run any Nix package directly in their browser by booting a Linux machine with WebAssembly, accessing over 310,000 package versions from nixpkgs history without requiring local installation. The innovation leverages existing binary caches (like cache.nixos.org and GitHub Pages) that support cross-origin access, enabling users to instantly search, select, and execute any package version or custom store paths in a browser-based terminal. This makes the browser a functional Nix client capable of running command-line programs from any point in nixpkgs history.
