Vibecoded Something That Works? Don't Blow It When You Scale.
I built something that works—and I'm scared to touch it.
Tech debt is piling up. I don't know if it will hold.
I need to scale, but the code feels fragile.
I'm afraid one wrong move will break everything.

Razoyo Agentic Audit · Your Codebase, Analyzed
AI Teammates That Find What’s Fragile Before It Breaks.
Your prototype works. But will it hold? Our agents scan every line, surface every risk, and fix it — before your users find it first.
Codebase ingested. 23,847 lines across 186 files. Running full test suite baseline now.
⚠ 19 FAILING of 47 tests. Core issue in billing/renewal.test.js: race condition in the subscription renewal queue. Two charge attempts firing simultaneously for the same user under concurrent load. Risk: HIGH
That explains the duplicate charge complaints we’ve been getting. How bad is this?
Reproducible at ~30 concurrent users — you’re at 50 now and growing. Fix: idempotency keys on Stripe charge calls + DB-level lock on the renewal job to guarantee exactly-once execution. PR #8 ready for review.
Reviewed PR #8. Fix is correct — idempotency keys prevent duplicate Stripe charges and the DB lock makes the renewal job atomic. This would have gotten much worse as you scaled. Merging now.
✅ 47/47 passing. Race condition non-reproducible up to 200 concurrent users tested.
That was a ticking time bomb. I had no idea. Thank you for catching it.
