Floorplan (haydenschmitty/floorplan, 2.1k stars, MIT) uses Claude or Codex to read your codebase and draw an interactive plain-English map of modules, files and web requests. It ships as a Claude Code/Codex plugin with a demo app. The screenshot shows it mapping a coffee e-commerce app's storefront, staff app, background jobs and third-party services, plus a health check that flags secrets committed to config.ts and unauthenticated endpoints—with one-click 'Fix with Claude' actions. Useful for onboarding onto unfamiliar codebases.
