LemonBeam

LemonBeam is an open-source utility designed to simplify code comprehension and developer onboarding. Key features include: • Codebase classification and chunking • Metadata indexing for accurate context • Source-backed architecture guide generation • Available as a web app, CLI, and local server integration This tool helps developers quickly understand unfamiliar JavaScript or TypeScript repositories by generating a fixed-format contributor guide. Instead of sending entire repositories to language models, LemonBeam intelligently classifies files, creates meaningful code chunks, and retrieves only the most relevant evidence for each section of the guide. This ensures a reliable and precise overview of project architecture. LemonBeam addresses the challenge of scattered information across various project files like READMEs, scripts, and source code. It employs a deterministic approach by scanning, classifying, organizing, and retrieving targeted evidence to produce a repeatable, source-backed guide with citations. This method eliminates onboarding fatigue and reduces the time new team members spend understanding a project. Ideal for engineering teams, open-source contributors, and project managers looking to streamline developer onboarding and improve code visibility. It can be integrated into existing workflows via its CLI tool for local project analysis or as an MCP server within tools like Claude Desktop.
