We fix vibe-coded apps without rewriting them.
You prompted an app into existence with Cursor, Lovable, Bolt, v0 or Claude, people signed up, and now the checkout fails for some users, pages take eight seconds, and every fix breaks something else. We stabilise what you have, in weeks, and hand it back documented.
This is for you if
- 1The app has paying or active users, so you cannot go dark for three months while someone rebuilds it.
- 2It was built mostly by prompting: one or two people, no tests, no staging, a 3,000-line file that does everything.
- 3The failures are the usual ones: slow queries once the table grew, auth that logs people out, Stripe webhooks that fire twice, API keys sitting in the client bundle.
- 4You want engineers who will tell you if the fix is two hours, not sell you a $60k rebuild.
- 5You are on a modern stack: Next.js or React, Supabase, Neon or Postgres, Vercel or similar, Stripe or Clerk. (Bubble and no-code apps have their own page.)
How the rescue runs
Same order every time, because the same things break every time. You keep shipping throughout.
1
Assessment, 48 hours, free
Read-only access to the repo and a staging URL. You get a written list of what is broken, ranked by damage, with hours against each item and a fixed price. Yours to keep either way.
2
Week 1: stop the bleeding
Error monitoring so you know before your users do. Indexes on the hot queries. Exposed secrets rotated and moved. Authorization checks on every endpoint that touches user data.
3
Weeks 2–3: the safety net
A staging environment that mirrors production. CI that runs on every push. Tests on the paths that make money: signup, checkout, webhooks. Database migrations so schema changes are tracked.
4
Week 3–4: refactor what hurts
Break up the god file into modules. Make Stripe and cron idempotent. Fix the N+1 queries. Only what is causing incidents; we do not refactor for aesthetics.
5
Handover
A written architecture note, runbooks for the things that page you, and a recorded walkthrough. Your next hire can read it and get to work.
What every rescue includes
- Sentry (or equivalent) wired up with alerts that go to you
- Index and query review on every table over a few thousand rows
- Secrets audit: nothing in the client bundle, nothing in git history
- Authorization review on every API route and Server Action
- Idempotent Stripe webhooks and cron jobs with a database-enforced dedupe
- Staging environment and a CI pipeline that blocks broken builds
- Tests on signup, login, checkout and the top three user flows
- A Slack channel with all three founders and a written Friday update
What it costs
Typical ranges from our engagements. The assessment replaces these with a fixed number.
| Scope | Typical price | Time |
|---|---|---|
| Targeted fixOne class of failure: a connection storm, a double-charge race, a redirect loop, a migration that will not deploy. | $1,500–$8,000 | 1–2 weeks |
| StabilisationThe full sequence above on an app with active users and several failing areas. | $15,000–$40,000 | 3–6 weeks |
| Stabilise and extendStabilisation plus the features that were blocked by the mess. | From $40,000 | 6–12 weeks |
USD, fixed price after the assessment. No retainer required. If your case is a two-hour fix, we will say so and bill two hours.
Questions we get about this
Will you rewrite my app?
Almost never. A rewrite means months without shipping and you lose everything you learned in production. We stabilise incrementally. If the data model genuinely cannot be saved, the assessment will say so with reasons, and we will scope the rewrite honestly.
Can I keep using Cursor or Lovable afterwards?
Yes, and most founders do. Part of the handover is a set of rules for the codebase (where things live, what must be idempotent, what needs a test) so AI tools produce code that fits instead of code that fights it.
What if I do not know what is wrong?
That is normal. Send the URL and whatever users have complained about. Finding the actual cause is what the assessment is for; symptoms like "it is slow" or "checkout sometimes fails" are enough to start.
Do you need production database access?
Not for the assessment. Read-only repo access and a staging login are enough. During the engagement we work through migrations and your deploy pipeline, and we ask for the minimum access each step needs.
How fast can you start?
The assessment starts within one business day of receiving access. Most rescues start the following Monday. If users are being charged twice right now, tell us and we will look the same day.

Your Vibe-Coded MVP Got Its First 1,000 Users. Now Everything Is on Fire.
Your AI-built MVP is crashing under real traffic? You're not alone. Here's the honest playbook for fixing vibe-coded apps without burning everything down.
Server Actions: Stop Double Charges (2026)
Fix double-submit Server Actions with idempotency keys, Redis rate limits, and retry-safe patterns (Next.js in 2026).
Next.js + Stripe Webhook Double-Credit Bug (2026)
Fix the common Next.js + Stripe double-credit bug: two writers, retries, and races. Patterns, costs, and a clean idempotent design (2026).
Supabase RLS + OFFSET Pagination Trap (2026)
OFFSET pagination + RLS can make Supabase feel slow. Spot it, fix policies, and switch to keyset pagination without breaking auth.
Drizzle + Neon on Vercel: Stop DB Connection Storms (2026)
Fix Neon + Drizzle connection storms on Vercel in 2026: pick the right driver, pool correctly, and stop too many connections.
Next.js Proxy Auth Loops with Clerk (2026)
Next.js renamed middleware to proxy. Here’s how that can break Clerk auth and how to stop 307 sign-in loops fast in 2026.
Send us the app. Assessment back in 48 hours.
One of the founders reads it, not a sales team. Within 48 hours you have a written assessment and a fixed price. If it is a two-hour fix, we tell you that too.
