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.
Cut developer onboarding from weeks to hours with interactive code visualization, automated documentation, and proven workflow strategies.
Master dependency graph analysis for large codebases. Learn why teams use graph visualization to reduce refactoring risks, accelerate onboarding, and prevent breaking changes.
