[PRO SERVICES / SECURE, FIX & IMPROVE]

Need Help Fixing or Securing
Your Vibe-Coded App?

You built it on Lovable, Bolt.new or Replit. It works. It has paying customers. It also has security holes, performance problems and bits that quietly don't work. We audit, secure, fix and improve the parts AI got wrong, so you can keep building with a clear head.

TO STOP THE BLEEDING

[THE TRUTH]

Vibe-coding the front is fine. The back is where it bites.

AI coding tools are excellent at the bit users see. Buttons, layouts, copy, animations. The back half is also vibe-codeable, but without someone who knows what good looks like, it goes live with the boundaries missing and shortcuts everywhere.

Auth, permissions, payments, data integrity, secrets, rate limits. Then the next layer: error handling that swallows things, queries that don't scale, features the AI half-finished, costs nobody's watching. The app runs, and "runs" looks identical to "safe and ready to grow" until it isn't.

If your app handles money, accounts, files, or anything a customer would notice when it broke, you want a human eye on the back half.

WHAT THE AI GAVE YOU

  • Public database with one anon key
  • API keys in the JavaScript bundle
  • Admin pages "hidden" by a route
  • Errors swallowed, users see blank pages
  • Slow queries, no caching, no indexes
  • Half-finished features nobody flagged

WHAT IT NEEDS

  • Row-level rules per user, per table
  • Secrets on the server, rotated
  • Role checks enforced server-side
  • Errors caught, logged and paged
  • Queries that scale past 100 users
  • The half-built features actually finished
[THE FIVE THINGS]

Five ways a vibe-coded app bites you first.

Public scans of Lovable, Bolt.new, Replit, v0 and other Supabase-backed apps keep turning up the same failures. Performance, reliability and the half-finished features come right after.

01

Open database

Supabase Row Level Security off, or a single policy reading true. Anyone with the public key reads, edits and deletes every row.

02

Secrets in the bundle

Stripe, OpenAI and service-role keys baked into JavaScript anyone can view-source. One copied key can spend money or access data outside the app.

03

Auth in the browser

Admin checks done in client-side React. Change one variable in dev tools and you're staff. Endpoints never verify "is this your record".

04

Payments on trust

Stripe and PayPal webhooks with no signature check. Anyone can POST "they paid" and the app believes them. Refunds, never reconciled.

05

No limits, no eyes

No rate limits on login, password reset or the LLM endpoint. One script can burn through API spend, and without logs you won't know which route did it.

[HOW WE WORK]

Where we come in.

Triage first, then fix, then improve. First pass is 24 to 48 hours: leaked keys, exposed data, broken auth, missing webhook checks. Then we rebuild the parts that need a real developer and finish the bits the AI half-built.

You keep the app you built. We keep the AI editor working alongside us, so you can carry on building after we leave.

BOOK A TRIAGE CALL
01

Triage (24 to 48 hours)

We get read access to your repo and Supabase. You get a one-page report: what's exposed today, what's slow or broken, what's half-finished, and how worried you should be about each. Fixed price, no slides.

02

Stop the bleeding

Rotate every leaked key. Turn RLS on with policies that actually match your roles. Sign your webhooks. Move admin work behind a real server. Add basic rate limits and error reporting. Days, not weeks.

03

Rebuild and finish what matters

Auth, payments, file storage, the LLM endpoint, the slow queries, the half-built features, the error paths the AI never wrote. Rewritten properly, tested, deployed somewhere you can monitor. The UI stays. The rest gets a backbone.

04

Hand back something you can grow

Backups running, alerts wired to your phone, an audit log you can search, a written list of what's safe to keep vibe-coding and what isn't. Optional retainer if you want us building the next set of features alongside you.

[IN THE WILD]

It already happened. Several times.

Three publicly reported incidents from the last year. All three were apps built on the same tools, the same way founders are building today.

CVE-2025-48757

170 Lovable apps, one scan.

Researcher Matt Palmer scanned 1,645 Lovable projects and found 303 vulnerable endpoints across 170 projects, about 10.3% of the sample. MITRE scored CVE-2025-48757 at CVSS 9.3; NVD lists it as disputed.

APR 2026

Public projects exposed build history.

Lovable said public project chat history and source code could be accessed by any Lovable user with a project link between 3 February 2026 and 20 April 2026. The company also said related reports were closed without escalation.

FEB 2026

18,697 user records.

The Register reported Taimur Khan found 16 vulnerabilities, six critical, in a Lovable-hosted education app with more than 100,000 views. The exposure covered 18,697 user records, including 4,538 student accounts.

[QUESTIONS]

The ones we get asked first.

Q.01

Do I have to throw the whole thing away?

Almost never. The UI is usually fine, often genuinely good. It's the back half that needs rewriting. We keep what works, replace what doesn't, and you carry on building.

Q.02

Can I keep using Lovable / Bolt / Replit after?

Yes. We leave the editor in place for the parts it's good at: layouts, marketing pages, copy changes, new screens. We give you a written list of which parts are safe to vibe-code and which need a developer.

Q.03

How fast can you start?

Triage on a fast turnaround if it's live and serving customers. Stop-the-bleeding work usually starts within days of the report. Full rebuild scoped from there.

Q.04

What do you actually need from me?

Read access to your repo, Supabase or Firebase, Stripe, and any hosting (Vercel, Netlify, Replit). That's it. We don't need a tech co-founder to translate. You can hand it to us non-technical and leave us to it.

Q.05

It's not just security. Stuff is slow, buggy, half-finished.

Same engagement. Triage flags it, the rebuild fixes it. Slow queries get indexed or rewritten, errors get caught and logged, the half-finished feature gets finished. Security comes first because the cost of getting it wrong is highest, but we don't leave the rest broken.

Q.06

How much does it cost?

Triage is fixed-fee. Stop-the-bleeding sprint is priced per finding. Full rebuilds are scoped against the report, fixed price per phase. We tell you the number before we touch a line of code.

Q.07

What if I've already been hit?

Call us first, not last. We work the incident: rotate, lock, scope what was taken, draft the customer notice, then fix the cause. We have done this. You don't want to be doing it on your own at 11pm.
