tree-sitter-language-pack
Pre-compiled tree-sitter grammars for 371 programming languages
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained (released 9 days ago), has no known vulnerabilities, uses a permissive MIT license, and solves a real problem—parsing 371 languages without compilation overhead. Medium install friction is acceptable given the breadth of language support and the lean dependency graph. Reach for it whenever you need to process or analyze code structurally.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; parsers are downloaded on first use and cached locally.
- Medium install friction due to platform-specific wheels (macOS, Linux, Windows, ARM variants), but wheels are pre-built and the package has active maintenance with a recent release (9 days old).
- Single runtime dependency on tree-sitter keeps the dependency graph lean.

What it is and what it does
tree-sitter-language-pack wraps the tree-sitter parsing library and bundles pre-compiled grammars for 371 languages behind a single Python API. Instead of managing individual language grammars and compilation, you install this package and call get_language() to receive a ready-to-use parser for any supported language. Parsers are downloaded on first use and cached locally, keeping the initial install small while supporting selective language installation.
The package is designed for code analysis, inspection, and extraction tasks: pulling out functions, classes, imports, and symbols from source; feeding code into RAG pipelines; or giving language models structural understanding of a codebase. It bundles standard tree-sitter query types (highlights, injections, locals, tags, indents, folds) per language and maintains a compiled-query cache. The single runtime dependency is tree-sitter itself, and it supports Python 3.10 through 3.14.
Use it for
- Extract functions, classes, and imports from source files for code indexing or documentation generation
- Prepare code chunks for retrieval-augmented generation (RAG) systems feeding language models
- Build developer tooling that needs to understand and navigate syntax trees across multiple languages
- Analyze and split large codebases into LLM-digestible pieces for code review or refactoring agents
- Implement syntax-aware code transformations or linting rules without writing language-specific parsers
