CodeFlow turns a GitHub repo into an interactive dependency map. Paste a URL or drag in a local folder and it renders the file graph in your browser, picks out singletons, factories and god objects, scans for hardcoded secrets and risky eval calls, and gives you an A-F health grade. Runs entirely client-side. MIT.

No install, no backend, no build step: it's one HTML file. Your code goes from GitHub straight to your browser and nowhere else. If you add a GitHub token to read private repos, the token lives only in tab memory and disappears when you close it. There's a free hosted version, or clone the repo and open the file. It also ships a GitHub Action that drops an SVG health card on your README, recomputed every merge.

For new engineers landing on a codebase, this is the fastest way to get oriented. For tech leads, the blast radius view answers 'if I change this file, what breaks.' For a polished architecture diagram in a doc, it works, but expect to clean up the export.

The catch: it's a heuristic static analyzer. The README says edges come from matching function names and explicit imports, so dynamic imports, reflection and renamed runtime references slip past it. Good for the shape of the system, not the truth of it.
