Production-readiness audits, by stack.
Every stack breaks in its own predictable ways. Pick yours to see the failure modes a senior engineer looks for first — then it's the same $49 audit: one human reads your actual code and tells you what's safe to launch.
Supabase
RLS gaps, the service_role key, open writes, tenant leaks — the data-layer bugs Supabase apps ship with.
See the Supabase failure modes → Next.js / ReactNext.js
Leaked NEXT_PUBLIC_ secrets, route handlers with no auth, server actions that trust the client.
See the Next.js failure modes → Lovable (React + Supabase)Lovable
Generated Supabase policies left open, keys in client code, and the "preview works, so it’s done" trap.
See the Lovable failure modes → Bolt.newBolt
Secrets generated into the client, backend rules in test mode, missing server-side authorization.
