AI Code Rescue · v0
v0 built the UI. Production needs everything underneath.
v0 is strong at interface generation. The failure mode is a polished front end sitting on thin auth, ad-hoc API routes, and zero operational readiness. We fix the stack under the screens.

v0-specific failure patterns we see
Searchers looking for “Fix v0 generated app” usually hit one of these. The tool is not the enemy — shipping without production foundations is.
UI-complete, backend-fragile
Screens look finished. Server actions and API routes are incomplete, inconsistently authorised, or talking to the database with no shared validation layer.
Client/server boundary confusion
Secrets and privileged logic accidentally shipped to the client. “use client” sprawl that kills performance and blurs security boundaries.
Design system without an application architecture
Beautiful components composed into an unmaintainable app. No domain model, no clear module boundaries, hard to onboard the next engineer.
Paired with Cursor into a maze
v0 for UI, Cursor for “the rest,” no shared standards. Two generators, zero ownership of architecture.
A short real example
SaaS dashboard from v0 + Cursor
A non-technical founder assembled a B2B dashboard with v0 screens and Cursor-filled API routes. Investors loved the demo. The first pilot customer found other tenants' data via a missing auth check.
What we found
- Authorisation checked in some routes, skipped in others
- Shared database queries without tenant scoping
- No integration tests on multi-tenant boundaries
Outcome: Centralised auth middleware, tenant isolation audited end-to-end, CI gates on critical paths. Pilot unblocked; fundraising technical DD passed.

Common questions
Do you keep the v0 UI?
When it is solid, yes. We usually keep the visual layer and rebuild the data, auth, and deploy foundations. Rewriting UI for the sake of it wastes runway.
Is this the same as a design polish?
No. Rescue is engineering: security, correctness, tests, and operations. If you only need UI iteration, stay in v0.
Pricing?
Free triage. Fixed rescue quotes typically £8,000–£50,000+ based on scope. CodeGuard monitoring from £750/month if you want ongoing scans after stabilisation.
