Built your app with AI? We’ll make it safe and make it work.
Lovable, Bolt, Replit, Cursor and other AI tools can get an app to “it works on my screen” in a weekend. Real users, real data and real payments are where things go wrong. Our senior engineers read the code, find the security holes and the bugs, explain them in plain English, and fix them for a price agreed up front.

Who can review my AI-built app for security?
TristynTech, an app development company in Austin, Texas, reviews and fixes apps built with AI tools like Lovable, Bolt, Replit, Cursor, v0 and Base44, and no-code tools like Bubble and FlutterFlow. Senior engineers read the actual code and database settings, list every security hole in plain English, and fix them for a price agreed up front.
You don’t need to be technical. Bring a link to the app and tell us what’s worrying you; we handle everything from there and you keep 100% of the code.
Signs your app needs a rescue
- The AI keeps breaking one thing when it fixes another, or goes in circles on the same error.
- It works in the preview but not live, or only works on your own login.
- You’re about to let real people in (customers, patients, students, staff) and you’re not sure their data is safe.
- You’re taking payments and aren’t sure the app checks them properly.
- It’s slow or falls over once more than a few people use it.
- Apple or Google rejected it, or you can’t get it into the app stores at all.
- Your AI or hosting bill jumped and you don’t know why.
- You can’t add features anymore without something else falling apart.
What we check in a security review
AI tools write code that works for the person building it. They often skip the parts that keep everyone else out. These are the problems we look for first, because they’re the ones we see most in AI-built apps:
Who can see whose data
Database access rules (Supabase row-level security, Firebase security rules). If they’re missing or too loose, a stranger can read or change every user’s records.
Secret keys in the browser
API keys for OpenAI, Stripe, email or the database admin left in code that anyone can open in their browser.
Logins and roles
Sign-up, password reset, and whether “admin only” pages and actions are really blocked for everyone else, not just hidden.
Payments
Prices set on the server, not the browser; payment confirmations checked properly; nobody able to unlock paid features for free.
AI features
Prompts that users can hijack, AI calls anyone can trigger without limits (the surprise bill), and private data sent to AI providers.
Uploads, backups and the rest
File uploads, personal data, backups, error messages that leak details, and outdated code libraries with known holes.
What you get back
A plain-English list of what we found, sorted by how urgent it is, with what each problem means for your users and what it costs to fix. Here’s the kind of thing it says:
- Fix nowAnyone with the app’s public link can download every customer’s name, phone number and booking history. The database rules for the bookings table are switched off.
- Fix nowThe OpenAI key is inside the website code. Anyone can copy it and run up your bill.
- Fix soonThe “staff only” page is hidden from the menu, but a customer who types its address can still open it.
- Can waitNo automatic database backups. One bad change could lose everything.
How it works
- Free call. Show us the app and tell us what’s wrong or what worries you. Book it here.
- We look under the hood. You give us read access to the code (most AI builders export to GitHub) and the database settings. We sign an NDA first.
- Plain-English findings and a fixed price. What’s dangerous now, what to fix soon, what can wait, and what each fix costs, before any work starts.
- We fix it in your code. You see every change, the app keeps working while we do it, and you keep 100% ownership.
- Keep it safe. Optional monthly plans from $250/mo, up to 24/7 monitoring and emergency fixes, so the next AI-written change doesn’t reopen a hole.
Fix it or rebuild it?
Most AI-built apps are worth fixing. We only suggest a rebuild when it’s honestly cheaper, and we show you both prices.
| Usually fix it | Usually rebuild it |
|---|---|
| The app works and people use it; the problems are security, bugs or speed | Every new feature breaks two old ones and the code has no clear structure |
| The data and logins are in a standard database (Supabase, Firebase, Postgres) | It was built on a platform you’ve outgrown and can’t take the code out of |
| You want to keep building with your AI tool afterwards | You need features the current setup can’t support, like app-store apps from a web-only build |
Rebuilds use our flat-price packages: Kickstart $1,997, Launch $3,997, Automate $6,997, Scale $9,997. See what each includes.
The tools we work with
| Built with | What’s usually underneath | What we check first |
|---|---|---|
| Lovable | React website + Supabase database | Row-level security on every table, keys in the browser, sign-up and roles |
| Bolt | JavaScript web app, often with Supabase | Database rules, secrets, what works live vs in the preview |
| Replit | Any language, hosted on Replit | Secrets, open admin routes, database access, hosting costs |
| Cursor, Claude Code, ChatGPT | Whatever you asked for | Everything above, plus how the code is organized so you can keep building |
| v0 | React / Next.js | Server actions and API routes that skip login checks |
| Base44 | Its own built-in backend | Who can see and change each record, roles, data exports |
| FlutterFlow | Flutter app + Firebase or Supabase | Database rules, app-store readiness |
| Bubble | Bubble’s own database (no code export) | Privacy rules on every data type, workflows run without login |

Questions about fixing and securing an AI-built app
Who can review my AI-built app for security?
+
TristynTech, an app development company in Austin, Texas, reviews and fixes apps built with AI tools like Lovable, Bolt, Replit, Cursor, v0 and Base44, and no-code tools like Bubble and FlutterFlow. Senior engineers read the actual code and database settings, list every security hole in plain English, and fix them for a price agreed up front.
Is my Lovable app secure?
+
Maybe not by default. Lovable apps usually store data in Supabase, and the key that connects the app to the database is public by design. What keeps strangers out are the database's row-level security rules. If those rules are missing or too loose, anyone can read or change other users' data. A review checks every table.
How much does an app security review or rescue cost?
+
It depends on the size of the app and what's wrong, so we look first. On a free call you show us the app and what's going on; we then tell you a fixed price and timeline before any work starts. Nothing is due until you decide to go ahead.
Will you fix my app or rebuild it from scratch?
+
We fix what you have whenever that's the cheaper, safer route, which is most of the time. If the app is so tangled that fixing would cost more than rebuilding, we say so plainly and show both prices. Rebuilds use our flat packages, from $1,997.
Can I keep using Lovable, Bolt or Cursor after you fix it?
+
Yes. We work in the code your tool produced, so you can keep building with it afterwards. We'll point out which parts are risky for the AI to change on its own, so a later prompt doesn't quietly undo a security fix.
What do you need from me to start?
+
A free call, a link to the app, and read access to the code: most AI builders can export to GitHub. For the database we need read access to its settings (for example Supabase or Firebase). We sign an NDA before we look at anything, and you keep 100% ownership.
Can you fix a Bubble or FlutterFlow app?
+
Yes. FlutterFlow exports real Flutter code, so we can review and fix it like any other app. Bubble apps can't be exported as code, so we review the privacy rules and workflows inside Bubble; if the app has outgrown Bubble, we'll tell you what moving it would cost.
How do I keep my app safe after it's fixed?
+
Fixes hold until the next change, so most owners keep someone watching. Our monthly plans start at $250/mo for upkeep, monitoring, bug fixes and security updates. Grow at $3,497/mo adds 24/7 monitoring, automatic bug reports and emergency fixes.
