DevLens

DevLens is an open-source CLI tool (AGPL v3) that transforms TypeScript and JavaScript repositories into interactive dependency graphs with AI-powered summaries and security analysis. Features include full AST parsing with 10+ relationship types, state intelligence (Redux, Zustand, Jotai), PageRank-based importance scoring, blast radius analysis for PRs, commit diff visualization, route detection (Next.js, Express, Fastify), and checkpoint/resume. Runs 100% locally — code never leaves your machine. Graph generation in 6-20 seconds for 500-2500+ nodes.
