Devlens maps your React/Next.js codebase into an interactive graph so you can understand dependencies, logic flow, and the blast radius of changes, with business logic summaries and technical summaries along with any severity issues. Built using AST analysis (no AI for mapping), it helps you see how components, hooks, and state connect—especially in large codebases. It can be used for Easy Onboarding for new members in team, or for seeing the blast radius of your PR, providing easy PR review.
