Rescue by tool
v0 rescue
v0 is good at the interface. The gaps show up behind it: no real authz, checks that only run in the browser, no idea which user owns which row. We either wire the frontend to a backend that checks, or harden the one you already sketched.
What we keep seeing in v0 projects
- Screens done, server thin
- Client-side checks treated as security
- API routes with no authz
- No tenancy model once a second user shows up
- Deploy config that was never written for a real environment

Same path as Vibe Code Rescue: about 48 hours to look, a severity ranking, then a fixed scope if you want the work done. Knowing the tool mostly means less of that time goes to surprises.
FAQ
Can you fix a v0-built app without rewriting it?
Often, yes, for a large part of the product. We will not promise that before we have seen it. The diagnostic says what to keep. The quote covers security, auth, data, and payments first.
How much does v0 rescue cost?
Same ladder as the rest of the rescue work: diagnostic free–$500, audit $299–$2,500, focused rescue $500–$12,500+. The numbers are on /pricing/.
