Finish my
v0 app.
v0 produces genuinely excellent React components — clean, accessible, well-structured markup that is a pleasure to build on. What it leaves undone is the part that decides whether you can charge money for the result. We audit the project, fix the gaps below, and take it to launch. Fixed price from $8,000, 2–6 weeks.
Typical stack: Next.js + React + Tailwind + shadcn/ui components
What we find in v0 projects.
Recurring patterns from the audits we run. Not every project has all of them, and most have at least three.
Components, not an application
v0 is a UI generator and does that job well. What arrives is an interface: no database, no auth, no business logic. Treating it as a finished app is the mistake, not the output.
Forms that submit nowhere
Beautiful, validated-looking forms with no server action behind them, or one that logs to the console. Users fill them in and nothing is stored.
No data fetching strategy
Hardcoded arrays where an API belongs. Adding real data means deciding on caching, revalidation and loading states from scratch.
No auth or authorisation
Dashboards and admin screens render for anyone. There is no session and nothing checks who is asking.
No error boundaries
One failing component takes down the whole page, because nothing is wrapped and nothing degrades gracefully.
How it works.
Audit
We read the code, the database rules and the accounts, then send you a written list of what is broken, what is dangerous, and what is fine. You get this whether or not you hire us for the fix.
Fixed scope and price
You get one number and one date, in writing. No hourly meter, no discovery phase that bills while nothing ships.
The hard 20%
Security, payments, auth, data, edge cases, performance. Working software in your hands every week, not status updates.
Launch
Product Hunt page, demo video, screenshots, analytics and SEO foundation. We are there on launch day and for the first fixes after.
$8,000and up
Typical project $8k–$25k
Timeline: 2–6 weeks
Everything moves into your accounts, so you own the code and the data. Built by Dan Marteens, 11 years of senior engineering, Orlando, Florida.
v0 questions.
Can v0 build a full application?
v0 generates the interface, and it does that very well. A working product also needs a database, authentication, business logic, payments and error handling — none of which v0 is designed to produce. The components are an excellent starting point, not a finished app.
What does it cost to turn v0 output into a real product?
Most projects run $8,000 to $25,000 over two to six weeks. Because the interface is already good, the work is almost entirely back end: data model, auth, server actions, payments and the error paths.
Do you reuse the v0 components?
Yes. They are clean, accessible and built on shadcn/ui, so they are worth keeping. We wire them to a real back end rather than rebuilding what already looks right.
Built with something else?
