v0 built you a beautiful front end with nothing behind it
v0 is an interface generator, not an application builder. Understanding that distinction saves most founders a month of confusion.
Last updated: 16 August 2026
Why v0 apps break in production
v0 generates high-quality React and Tailwind interfaces, and that is deliberately all it does — there is no database, no authentication and no payments underneath. Foundreco audits a v0 project in 72 hours and quotes one fixed price to build the backend it needs, starting at $1,500.
Symptoms specific to v0
What actually breaks in v0 projects
No persistence layer at all
v0 output holds state in the component. Refresh the page and it is gone. Turning that into a product means designing and building an actual database.
Authentication that is only a screen
The sign-in form is a form. There is no session, no password handling and no authorisation behind it.
Mock data standing in for an API
Arrays hardcoded into components look convincing in a demo and have to be replaced entirely with real endpoints.
No server-side validation
With no backend, nothing validates anything. Every rule enforced in the interface can be bypassed.
Can you take your v0 code with you?
v0 code is standard React and Tailwind that you own outright and can move anywhere. The rescue keeps the interface — it is usually genuinely good — and builds the database, authentication and API underneath it.
What happens next
Send the v0 project link and the audit comes back inside 72 hours, severity-ranked, with one fixed price from $1,500 to approve or walk away from. If it should be rebuilt rather than repaired the audit says so, and the fee comes off the rebuild. The six steps and the rescue-or-rebuild table are on the rescue hub; every price is on the pricing page.

- Cursor rescue — cursor codebase refactor service.
- Base44 rescue — base44 app broken fix.
