Paste any GitHub URL → interactive architecture map. See how files connect, find what breaks if you change something. No install, no accounts — runs entirely in your browser.
The Lens
CodeFlow turns a GitHub repo into an interactive dependency map. Paste a URL or drag a folder, it renders the file graph in your browser, picks out singletons and factories and god objects, scans for hardcoded secrets, and gives you an A-F health grade. Runs entirely client-side. MIT.
No install. No backend. Your code never leaves the browser unless you set a GitHub token to read private repos, and even then it stays in tab memory. There's a Vercel-hosted version you can use right now, or clone and run locally. The repo 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 doing code review: the blast radius feature actually answers the question 'if I change this file, what breaks.' For anyone wanting a polished architecture diagram for a doc: works fine, but expect to clean up the export.
It's a static analyzer, not a runtime profiler. Dependency edges come from imports, not from what actually executes. Dynamic dispatch, reflection, and string-based requires will fool it. Good for the shape of the system, not the truth of it.
