Keep your code, add what’s missing
When the code is solid, we keep it and add the security fixes, tests, alerts and hosting it needs.
For apps built with AI tools
Your app works, and people use it. But can one customer see another customer’s data? Our U.S.‑based senior engineers find the security holes, close them, and add the tests and alerts your app is missing. The price is fixed. If the work runs over, we pay the difference.
The free code audit tells you whether to fix, rebuild or leave your app. Most fixes cost $15K to $30K, with a 12‑month bug‑free warranty on our work.
A vibe coded app is one built mostly by an AI tool, such as Lovable, Replit, Cursor or Bolt. The Gnar Company makes these apps safe for real customers. It finds and closes security holes, adds tests and alerts, and sets up hosting. Its senior engineers are U.S.‑based, the price is fixed, and the work has a 12‑month bug‑free warranty.

What changes
We look for security holes and close the ones we find: one customer seeing another customer’s data, secret keys left in the code, or pages that skip the login.
Automated tests check what your users do most, like signing in, saving and searching. A change that breaks one gets caught before your users see it.
If the live app goes down or starts showing errors, your team gets an alert.
We set up your hosting, your database and the tools your app connects to, so the app is ready for your users.
Two ways in
We read your code and tell you which one you need. If it can be changed safely, we keep it and fix it. If it can’t, starting over often costs less than patching it.
When the code is solid, we keep it and add the security fixes, tests, alerts and hosting it needs.
When the code can’t be changed safely, we rebuild the app at a fixed price, with the same warranty.

How it works
You get the fixed price before any work starts.
Under an NDA (a privacy agreement), we read your code and learn what the app does and who uses it. Then we tell you what we found: fix it, rebuild it, or leave it as it is.
We fix what the audit found, or rebuild what can’t be fixed safely, with a 12‑month bug‑free warranty. We call this Gnar Forge, our fixed‑price project.
Want us to keep it running? Maintain, our monthly support plan, covers hosting, monitoring and support from $1,000 a month. It’s optional.
Common questions
Still have questions?
The Gnar Company can. Our U.S.-based senior engineers fix apps built in Lovable, Replit, Cursor and similar tools. We close the security holes we find and add the tests, alerts and hosting the app is missing, or rebuild the parts that can’t be saved. This work usually runs as Gnar Forge, our fixed-price project for smaller builds.
Yes. The Gnar Company takes Replit and Cursor apps to production, and Lovable and Bolt apps too, whether you have your first users or the app is already breaking. We read what’s there, then fix it or rebuild it at a fixed price. The result comes with a 12-month bug-free warranty.
Get the code checked before you add the next feature. The Gnar Company starts with a free code audit, done under an NDA. It tells you whether to fix the app, rebuild it, or leave it as it is. If your own engineers can do the fix, we’ll say so.
Not until someone checks it. A working demo doesn’t show whether one customer can see another customer’s records, or whether logins and permissions really work. The Gnar Company’s free code audit is that check, done under an NDA. If we take on the fix, closing what the audit found is part of the job.
Most Gnar Forge projects fall between $15K and $30K, including rebuilding something that was vibe coded and broke. The code audit before that is free. Either way, you’ll know the fixed price before the project starts, and that price is guaranteed.
Get it audited first, then fix it or rebuild it. The Gnar Company tells you which. If the code is solid, we keep it and add the security, tests and alerts it’s missing. If it can’t be changed safely, starting over often costs less than patching it. Either way, you get a solid version of your app with a 12-month bug-free warranty.
It covers what we deliver. On a Gnar Forge project, The Gnar Company makes three promises. The price is fixed, and if the work runs over, we pay the difference. The app will do what we agreed it would do. And for 12 months, if something we built doesn’t work as agreed, we fix it at no charge.
Often your own engineers should, if they have the time and know what to fix. The Gnar Company will tell you that on the call. If nobody inside can take it on, that’s where we come in. Whoever does the work, ask what happens when something breaks after. We back ours with three guarantees: a fixed price, a result that works as agreed, and a 12-month bug-free warranty.
The code is yours, in your own repository, with notes so another engineer can pick it up. The Gnar Company’s 12-month warranty covers code we delivered that doesn’t work as agreed. If you want ongoing help, our monthly support plan, called Maintain, covers hosting, monitoring and support from $1,000 a month. It’s optional.
Start here
Start with a free code audit. We sign an NDA before we see your code. If your app is in good shape, or your own engineers can do the fix, we’ll say so. The audit is free either way.
