How much does it cost to fix a Lovable or Base44 app?

"How much will it cost to fix my app?" is the question I get most from founders who built with Lovable or Base44. The honest answer is "it depends", which isn't useful on its own. So here are the ranges from the prices we publish: what finding the problems costs (nothing, to start), what one fix and a handful of fixes come to on a worked example, what a launch-ready app costs, and when a rebuild is cheaper than fixing.

The short version

• Finding out is free. The Launch Check reads a live app in about a minute with no sign-up, and the AI audit reads the code: three audits per account, with a price range for every fix it finds.
• On a worked example (a small Lovable booking app with five findings), the cheapest single fix comes to $200–$225 and the dearest to $875–$1,625. All five together come to $1,175–$2,175, far less than the five fixed one at a time.
• Making the whole app ready for paying customers is App Launch Readiness, from $2,499. App Store submission starts at $499 per store, and monthly support for a Base44 app is $399.
• A rebuild is cheaper when the fixes touch most of the app, the data model is wrong at the root, or the first version is small: a Starter MVP on Base44 or Lovable starts at $1,499, a code-owned MVP Build at $9,999.

It depends on the app, so look first

What a fix costs depends on what is broken, how much of the app it touches and how many things you fix at once. An honest price starts with a look at the app, and that look should cost nothing. These are the prices we publish (USD, starting prices, fixed in writing after review, as of 23 October 2026), so you can place your app on the scale before you talk to anyone:

A worked example: five findings, priced

Our free AI audit page has a fix planner you can try on example findings from a small fitness-studio booking app built with Lovable. It's an example, not a client. Each total is what the planner shows for that selection, worked out the way every report does it: learning the project, the fix itself, testing and release. They're AI estimates, not quotes.

Three things stand out:

1. Batches cost less. Add up the five single totals and you get far more than the all-five total, because learning the project, testing and release are shared across the fixes.
2. Money and access cost the most. The two High findings are most of the bill, because payments and access rules have to be tested as each kind of user and in payment test mode.
3. Small fixes are small. An isolated fix, like escaping one email template, comes to a few hundred dollars in all.

What drives the cost

• How much of the app the problem touches. A missing check in one place is one fix. The same missing check on every screen is still one fix, applied and tested everywhere, and we price a repeated pattern once.
• Money and personal data. Payments, webhooks, sign-in and access rules need more testing than a layout change.
• The size of the app. Every estimate includes the hours to learn the project, scaled to its screens, data and integrations.
• How many fixes you do at once. Shared work is paid for once per batch, not once per fix.
• Whether the app has tests. Without them, every fix needs more checking of the journeys around it.
• What's not in the price unless the proposal says so: hosting, platform subscriptions and credits, AI usage, paid tools and taxes.

When a rebuild is cheaper than fixing

Compare the audit's total for everything you'd fix with the price of building the same first version again. When the two come close, price the rebuild too: you get a clean foundation for the same money. Rebuild when:

• the fixes touch most of the app, not a few journeys;
• the data model is wrong at the root (the same data written from many places, or business rules copied into every screen);
• the first version is small: one audience and one core journey, with few real users or records to move;
• you need something the platform can't give you, like your own backend or hosting. Then compare a migration with a rebuild.

Fixing is cheaper when the problems sit in a few workflows, you can say what should happen and show where it fails, the platform supports the feature and it was just configured or built wrongly, and paying users and real data are already in the app.

How to get your own number

1. Run the free Launch Check on the live app: about a minute, no sign-up.
2. Run the free AI audit on the code: paste a GitHub link, connect GitHub or upload a ZIP. Tick the findings you want fixed and the fix plan shows the range.
3. Send the plan to us. An engineer confirms the scope and gives one fixed price in writing before any work starts.

Whoever you hire, ask for written acceptance checks. Ours come with every fixed-price project, and for 30 days after handover, if something we fixed breaks again without anyone changing it, we fix it free.
