Vibe-Coded App Rescue: Make Your Lovable, Bolt or Cursor App Production-Ready
Your app was built quickly with Lovable, Bolt, Replit, Cursor or v0, and now real users, real data or real payments are arriving. We read the code, fix what is unsafe, stabilise what keeps breaking and put proper deployments in place, then hand it back to you or support it on an ongoing basis. You keep the product you have already built wherever it is sound.
App Rescue at a Glance
| Apps we rescue | Apps built with Lovable, Bolt, Replit, Cursor or v0, typically React or Next.js on Supabase and PostgreSQL, often with Stripe |
|---|---|
| How it starts | A fixed-scope assessment of your codebase, quoted after a short call. Book the call, or start with the free readiness checker. |
| Stages | Assessment, then a stabilisation sprint, then hand-over or an ongoing support retainer |
| Security focus | Supabase row level security (RLS), secrets kept out of the browser, privileged logic moved into server-side functions, verified webhooks |
| Communication | A dedicated Slack channel and bi-weekly video walkthroughs |
| Confidentiality | We are happy to sign your mutual NDA, or provide ours, before reviewing your code |
| Ownership | You own the full IP: the code, the database and the documentation |
We do not publish a fixed price for rescue work, because the effort depends on what the assessment finds.
Sound Familiar?
Fix One Thing, Break Three
Each prompt to the AI tool solves the immediate problem and quietly changes code elsewhere, so regressions pile up faster than you can test for them.
Works in Preview, Fails in Production
The app behaves in the builder's preview, then fails on a real domain with real data, environment variables and third-party services.
Keys and Data in the Browser
API keys, service credentials or unrestricted database access end up in client-side code, where anyone can read them.
Nobody Left Who Understands It
The code was generated rather than designed, so there is no documentation, no tests and no one who can explain why it works.
What We Usually Find, and What We Fix
Missing or Permissive Row Level Security
AI-generated Supabase projects often ship with RLS disabled or with policies that let any signed-in user read other users' rows. We write and test policies per table and role, the same approach we use for multi-tenant SaaS with Postgres RLS.
Secrets Moved Out of the Client
Service keys and third-party API credentials are moved into server-side environment variables, and exposed keys are rotated.
Privileged Logic in Server-Side Functions
Payments, emails, admin actions and AI calls are moved from the browser into server-side functions or API routes with proper authorisation checks.
Verified, Retried Webhooks
Stripe and other webhooks are signature-verified and handled idempotently, so payments and subscriptions stay in sync with your database.
Repository, Staging and Deployments
Code in a Git repository you own, a staging environment that mirrors production, and repeatable deployments instead of publishing straight from the builder.
Tests, Monitoring and Documentation
Tests on the critical paths, error monitoring, and written notes on how the app fits together. Our guide to custom web application security covers the wider checklist.
Rescue, Refactor or Rebuild?
| Rescue (stabilise) | Refactor | Rebuild | |
|---|---|---|---|
| When it fits | The product works for users, but it is insecure, fragile or hard to deploy | The core is sound, but some areas are tangled enough that every change breaks something | The data model or architecture cannot support what the product now needs |
| What changes | Security fixes, RLS policies, secrets, deployments, monitoring | Selected modules are restructured and covered by tests | A new codebase, using the existing app as a working specification |
| What you keep | Almost everything users see | The screens, data and most of the code | Your data, your learnings and the proven workflows |
| Disruption for users | Low: fixes ship behind staging | Moderate: changes roll out area by area | Higher: a planned migration and switchover |
| How we decide | The assessment report recommends one route, with the reasons | The assessment report recommends one route, with the reasons | The assessment report recommends one route, with the reasons |
Who App Rescue Is For, and Who It Is Not For
This is for you if
You have users, or are about to
The app is live or close to launch, and you need it to hold up under real users, real data or real payments.
Every fix breaks something else
Prompting the AI tool for one change now causes regressions elsewhere, and you no longer trust a deploy.
You are unsure what is exposed
You do not know whether your database policies, API keys or payment webhooks are safe, and you want someone to check.
The person who built it has moved on
A freelancer, co-founder or contractor built the app and is no longer available to support it.
Not the right fit if
Marketing websites
If you need a brochure site or landing page fixed, a web designer or site builder is a better fit.
One-off small bug fixes
We work in structured engagements starting with an assessment, not single quick fixes.
A fixed quote before we see the code
We cannot price a rescue responsibly without reading the codebase first. That is what the assessment is for.
An idea with no users yet
If the product has not been tested with users yet, validate the idea first, or plan a properly scoped first version through our MVP development service.
Stack We Work In
How a Rescue Runs
Fixed-Scope Codebase Assessment
AssessWe review the code, database policies, secrets, integrations and deployment set-up, then give you a written report: what is unsafe, what is fragile, what is fine, and whether to rescue, refactor or rebuild. The assessment is quoted after a short call.
Stabilisation Sprint
StabiliseWe fix the security issues first (RLS policies, exposed secrets, client-side privileged logic), then put a repository, staging environment and monitoring in place, with progress shown in bi-weekly video walkthroughs.
Hand-Over or Ongoing Retainer
Hand Over or SupportYou get documentation and a clean hand-over to your own team, or you move into a maintenance retainer where we keep the app secure and ship new features as separately scoped phases.
Vibe-Coded App Rescue case studies
Authenticated architecture deployments matching this service capability. Note: specific data flows are explicitly abstracted ensuring client confidentiality.
NDA Constraints Protected
Direct architectural blueprints for this specific service layer are strictly governed by enterprise NDAs and cannot be openly previewed. We encourage inspecting our Full Capability List instead.
Rescue Work Under NDA
Enterprise Verification
Engineering integrity is our only metric. Per strict institutional Non-Disclosure Agreements governing this capability space, we do not publicly disclose internal client profiles, metric hallucinations, or unmapped claims.
Common Rescue Risks
Fixing Directly in Production
Changing a live app without a staging environment turns every fix into a gamble with real users' data.
Security Fixes That Break Features
Turning on RLS or moving logic server-side can stop screens working that silently relied on open access.
How We Handle Those Risks
Staging Before Anything Else
We set up a staging copy early, so security fixes are tested against realistic data before they reach users.
Small, Reviewed Changes
Policies and server-side functions are introduced feature by feature, with each change tested and shown to you before release.
