LemonBeam is an open-source developer utility that eliminates onboarding fatigue. Instead of blindly dumping entire repositories into an LLM, it classifies files, chunks code using Tree-sitter, and indexes metadata to generate accurate, source-backed architecture guides. Available as a web app, a terminal CLI, and a local MCP server for Claude.
