Who can fix my Lovable app before launch?

I can, and so can a certified Lovable partner, a freelancer or an agency. Small bugs you can often fix yourself with prompts. I am a senior full-stack engineer who reviews, fixes and launches Lovable apps, at published prices starting with a $995 Tech Check.

A scan finished in March 2025 checked the homepages of 1,645 Lovable sites and found 303 exposed endpoints across 170 of them, about 10.3% (CVE-2025-48757).

What usually breaks in a Lovable app

Lovable writes a React front end and gives it a backend: its built-in Cloud, or a Supabase project you connect yourself. The front end usually talks to the database directly, so the access rules on each table are what stop one user from reading another user’s data.

  • Row-level security off, or rules that let any logged-in user read every row.
  • Stripe payments that work in test mode but never update the database in production.
  • Password reset and magic links that point to localhost or the preview URL.
  • A secret key in the front-end code or the GitHub repo. Supabase’s secret key skips every row-level security rule.
  • No tested way back. Reverting a version in Lovable restores your code, not your database data.
  • No separate test database. A Git branch does not give you one, so a test can touch real users’ data.

Grid of 100 squares with about 10 highlighted: 170 of 1,645 Lovable sites, about 10.3%, had exposed endpoints in a scan finished in March 2025. The scan covered homepages only.

The scan is from March 2025 and covered homepages only, not logged-in pages. Its author works at Replit, a competitor. Lovable has added security scans since, so treat this as a sign of the risk, not a current rate.

Who can fix it

It depends on what a mistake would cost you. If the app holds user data or takes payments, have a senior engineer read it before launch. If it is one small bug and a mistake is cheap, the cheaper routes are fine.

  • You, with prompts. Good for layout, copy and small bugs. Lovable scans your database rules every time you publish, and its docs say these tools β€œdo not replace a thorough security review”.
  • A Fiverr gig. Good for one small bug you can describe in a sentence. On 29 Oct 2026, gigs for β€œlovable app fix” had a median starting price of $35, before Fiverr’s buyer fee.
  • An Upwork freelancer. Upwork lists $16 to $35 an hour for full-stack developers and $51 to $75 for React developers. Ask to see row-level security work they have done, not just React.
  • A certified Lovable partner. Lovable lists Experts and Solution Partners in its own directory. Prices are not published, so you agree them with the partner.
  • An agency. Good for a big app and a team of several people. Relux, for example, publishes a $3,000 rescue audit, then fixes from $10,000 up to about $40,000.
  • Me. One senior engineer, fixed published prices, and you talk to the person doing the work. The details are below.

Range chart of Lovable fix prices, October 2026, on a log scale: Lovable Pro $25 a month, Fiverr gigs $5 to $750 with a $35 median, Upwork fixed budgets $5 to $4,000 with a $500 median, badii.studio Tech Check $995, Relux audit $3,000, Relux fixes $10,000 to $40,000.

Prices were read on 29 Oct 2026, and the Relux prices again on 5 Nov 2026. These routes buy different amounts of work, so a higher price usually means a bigger scope. The full breakdown is at badii.studio/cost-to-fix-lovable-app.

Six checks you can do today

  • Database rules. In Supabase, open Advisors, then Security Advisor. An error saying RLS is disabled on a public table means anyone with your project URL can read, edit and delete that data. On Lovable Cloud, read the results of the security scan.
  • Two test users. Log in as one user, open the browser network tab, and find a request for that user’s data. If changing the user id in it returns another user’s rows, your rules are too open.
  • A real payment. Pay once in live mode, then refund it. The plan in your app should change, and Stripe should show the delivery as successful under Workbench, Webhooks, Event deliveries.
  • Password reset. Send yourself a reset email from the live app. The link has to open your live domain, not localhost or a preview URL.
  • Secret keys. Search the repo and the site’s loaded JavaScript for sb_secret_, service_role and sk_live_. You want zero hits. If you find one, replace the key, because deleting the line does not make it safe.
  • A way back. Find out where your database backup is before you need it. Lovable Cloud keeps daily backups for about 14 days, Supabase backs up paid plans daily, and on the Supabase Free plan you export your own.

Checklist of six checks before launching a Lovable app: database rules, two test users, a real payment, password reset, secret keys, and a way back.

The same six checks on one page, for your team or your next launch.

What I do

I connect to your GitHub repo and your backend with read-only access, read the code and the access rules by hand, and test the flows that matter: sign-up, payment, reset, and data access between users. You keep building in Lovable. I fix in the same repo, and Lovable’s GitHub sync works both ways, so my changes show up in your project.

How it works

  • Free teardown: a 5 to 10 min recording of what a stranger can see and break in your live Lovable app.
  • Tech Check, $995, one time: I read the code and the backend and send findings ranked by risk and a written plan in 5 business days.
  • Builder seat, $4,995 a month: the issues fixed one request at a time, then the app taken live. Pause or cancel anytime.
