ChunkHound’s goal is simple: local-first codebase intelligence that helps you pull deep, core-dev-level insights on demand, generate always-up-to-date docs, and scale from small repos to enterprise monorepos — while staying free + open source and provider-agnostic (VoyageAI / OpenAI / Qwen3, Anthropic / OpenAI / Gemini / Grok, and more).I’d love your feedback — and if you have, thank you for being part of the journey!

Could you build this?
Partial Basic repository RAG and LLM doc-gen can be vibe-coded, but scaling local-first AST parsing and incremental vector indexing to enterprise monorepos requires specialized systems engineering.
What it would actually take: A robust local-first codebase intelligence tool typically uses tree-sitter or LSP engines for precise cross-reference graphs, coupled with an embedded vector store (like SQLite-vec or LanceDB) and high-throughput embedding models. The hard part is incremental dependency-aware indexing across multi-gigabyte repos without crashing local memory or choking on deep monorepo trees. It requires expertise in compiler frontend tooling, abstract syntax trees, and low-resource local data storage.
