Short answer: for a small app built with Lovable, Bolt, Replit or Cursor, published prices from specialists in 2026 mostly fall between $1,500 and $8,000 to audit and fix it properly. A single bug fix from a freelancer can cost a few hundred dollars. At the far end, a full rebuild quoted by larger firms runs $20,000 to $60,000. Where your app lands depends less on how many screens it has and more on four things: how messy the database rules are, whether secrets have leaked, whether payments are involved, and how easily someone can get access to everything.
Below are the real published prices we found, what drives them, and how to keep your bill at the low end.
What people actually charge (published prices, 2026)
These are prices companies publish on their own sites or that were collected in public price roundups. They're a snapshot, not a quote.
| Who | What | Published price |
|---|---|---|
| Marketplace freelancers | Single fix / "make my app production-ready" packages | From about $100 to $1,200 on Upwork (example listing); freelance quick fixes from $299 (AxonBuild roundup) |
| Launch Ready Code | Automated scan + audit report | Free scan, $499 audit report, monitoring $149–$599/month, done-for-you setup $1,999 (Launch Ready Code) |
| vibecoding.app | Cleanup specialist | $500 quick check, $1,500 audit, $3,000–$5,000 audit plus fixes, $5,000–$8,000 full package (vibecoding.app) |
| Specialist and rescue agencies (roundup) | Audit and fix | $1,500–$5,000 specialist, $3,000–$8,000 full-stack rescue, $8,000–$15,000+ enterprise security firms (AxonBuild roundup) |
| Larger development firms | Fix in place vs rebuild | Fix in place $3,000–$15,000 over 2–6 weeks, rebuild $20,000–$60,000 over 8–16 weeks (AxonBuild roundup citing InApps) |
For context, a typical Upwork web developer charges around $15 to $50 an hour (Upwork), while freelance developers in the US average $95 to $110 and in the UK $75 to $95 an hour (Index.dev). Hourly price alone tells you little. A cheap developer who fixes the wrong thing costs more than an expensive one who fixes the right thing once.
The four things that really drive the cost
1. How wrong the database rules are
Most AI-built apps use Supabase or Firebase, where security lives in database rules (Row Level Security in Supabase). If the rules are missing on one table, that's a quick fix. If every table uses "any logged-in user can read everything", someone has to work out, table by table, who should see what, then test it with multiple accounts. That takes most of the time in a typical audit.
2. Whether secrets have leaked
If a secret key (a Supabase service_role or secret key, a Stripe secret key, an OpenAI key) has ever been in your frontend code or a public GitHub repo, fixing the code isn't enough. Every exposed key has to be rotated, and every service that used it updated. As one pricing roundup puts it, secrets in git history mean rotating credentials across all dependent services (AxonBuild). If you're on Supabase, you'll also want to switch to its new key system, since the old keys are retired by the end of 2026 (our guide).
3. Payments
An app that takes money needs its payment flow checked end to end. Does the server confirm payment through a verified webhook, or does the browser decide? Can someone cancel and keep access? Are refunds and failed renewals handled? Payment work is where you least want shortcuts, and it adds time.
4. Access and setup
This one surprises people. A surprising share of a fix goes on simply getting in: finding who owns the GitHub repo, the Supabase project, the domain and the Stripe account, and getting access to each. With no staging copy of the app, every fix has to be tested carefully on the live version, which is slower. With no automated tests, every change is checked by hand (AxonBuild).
