A comprehensive collection of tree-sitter language parsers with polyglot bindings — 306 languages, one Rust core, downloaded on demand.

What and Why?

tree-sitter generates fast, incremental parsers from grammars for any programming language. As agentic tooling makes processing, inspecting, and analyzing code ever more critical, tree-sitter-language-pack bundles the most comprehensive collection of grammars available behind a single API.

The core is written in Rust with polyglot bindings for 15 other languages, plus a CLI and MCP server for working with code from the shell. Grammars are built into multi-platform binaries and downloaded on demand, so the package stays small while offering 300+ parsers.
