nixd is a feature-rich language server for the Nix language, built in C++ on top of the Nix libraries. It provides editor intelligence such as Nixpkgs option completion, lazy package completion, shared eval caches, and cross-file goto-definition.

Use cases

• get nix autocomplete and diagnostics in my editor
• language server for nix with nixpkgs option completion
• goto definition into nixpkgs from my nix config
• lsp server for editing nixos and home-manager configurations
• share nix evaluation caches with my language server
• set up a reproducible nix editing environment

When to choose

• you write Nix, NixOS, home-manager, or flake-parts configuration and want rich editor support
• you want deep nixpkgs integration like option and package completion
• you want a language server that shares eval caches with your system Nix

When to avoid

• you don't work with the Nix language
• you need a language server for another language
• you want a minimal LSP without nix library dependencies
