You Vibe Coded Your App. What Will It Actually Cost an Agency to Finish It?
Lovable, Replit, Bolt and other AI builders can get you surprisingly far. But getting from “it works” to “real customers can use it” is where the remaining work — and cost — can vary dramatically.
Here's a simple way to understand where your project stands before you ask for a quote.
Most AI-App Finishing Projects Fall Into One of Four Buckets
These are market-informed ranges, not fixed quotes. Two projects that look similar can require very different amounts of work underneath.

Your App Can Look 95% Finished and Still Be Far From Launch
What You See
Beautiful screens
Working buttons
Login page
Dashboard
Demo data
Animations
What Real Users Need
Secure accounts
Real data
Reliable payments
Working integrations
Error handling
Security checks
Testing
Deployment
Monitoring
AI builders are excellent at getting an idea onto the screen. Launching a product means making sure everything behind that screen works reliably too.
Before You Pay Anyone to Finish It, Check These 8 Things
Can people actually sign up and log in?
Is their information being stored correctly?
Do payments work, including failed payments?
Do your integrations actually work?
What happens when something goes wrong?
Can one user accidentally see another user's information?
Can the app handle real users, not just your test account?
Can it be deployed, monitored and maintained after launch?
If you answered “not sure” to several of these, don't assume your app is almost finished. It may simply be visually finished.
Four Things Can Change the Cost Dramatically
What's Missing
More unfinished features means more work.
How Much Can Be Kept
Clean existing code can reduce work. Fragile, duplicated or incomplete code can increase it.
What the App Connects To
Payments, CRMs, maps, email, AI APIs, calendars, databases and other integrations add complexity.
How Safe It Needs to Be
An internal prototype is very different from an app handling payments or customer data.

We Don't Guess the Price From the AI Builder You Used
Lovable, Replit, Bolt or Cursor doesn't tell us what your project will cost. We need to see what's actually there.
01
Free Assessment
We review what you've built, at no cost.
02
Review What Exists
We go through the codebase, not just the demo.
03
Identify What's Missing
Features, integrations, and production gaps.
04
Decide What Can Stay
Keep what works. Flag what doesn't.
05
Define the Finishing Scope
A clear list of exactly what's left to build.
06
Fixed Project Price
Agreed upfront, before work begins.
07
Build → Test → Launch
Development, QA, and a real launch.
Eligible projects can use FlexPay: 30% upfront, with the remaining balance spread over 3–12 months with no interest. See the pricing page for more on how it works.
FAQ
Typically $3k–$30k+, depending on how much is already built, what's still missing, and how production-ready it needs to be. Most Lovable projects land in the $8k–$15k range — functional, but missing real authentication, payments, or key workflows.
The same ranges apply — cost follows what's actually left to build, not which tool you started with. Replit projects often need more backend and production-hardening work, which can push them toward the $15k–$30k+ range.
Yes, as long as the codebase can be accessed and is technically workable. We review what exists before quoting anything, regardless of who built it or which AI tool was used.
Usually not. Most projects keep the working parts and finish what's missing. A full rebuild is only needed when the underlying architecture can't safely support what the product needs to do.
Yes. Deployment, app store submission, and getting the product to a production-ready state are part of the finishing work, not a separate add-on you have to arrange elsewhere.
Run through the self-diagnosis and 8-point checklist above for a rough idea, then get a free project assessment — that's the only way to get a number based on your actual codebase, not a guess.
This is exactly the process behind Web&Buzz's Finish Your App service. If you're building a mobile app from scratch instead, the same team also handles new mobile app builds. Before you launch, it's also worth running through our AI app security checklist, and if you want to see what a finish project looks like end to end, the Tocify case study walks through a real Lovable project taken from prototype to a live product.
