AI App Rescue

Your AI-built app shipped fast but now it's breaking. We stabilise, secure, and maintain AI-generated applications so your users stop experiencing failures.

Your AI-generated app shipped fast — but now it's breaking under real users, and every patch creates two new bugs. We specialise in rescuing these applications: stabilising what works, fixing what doesn't, and putting you on a path to sustainable maintenance.

What's included

  • Critical bug stabilisation within days
  • Security hardening and vulnerability remediation
  • Architecture refactoring without full rewrite
  • Performance triage and optimisation
  • Test coverage and CI/CD pipeline setup

Architecture varies per project — this represents our standard production pattern for this service.

Our Process

01

Triage

Review the codebase, identify critical failures, and deliver a prioritised fix plan with honest effort estimates.

02

Stabilise

Ship fixes for the issues causing real user pain. Deploy monitoring so you see improvement in real time.

03

Harden

Security audit, test coverage, performance fixes, and architecture improvements for long-term maintainability.

04

Maintain

Ongoing support to keep the application healthy, handle updates, and prevent regression as you add features.

Sentry

Why clients choose us

  • End-to-end ownership — no agency hand-offs
  • Architecture documented before any code is written
  • Tests written alongside features, not as an afterthought
  • Fixed-price phases with clear deliverables

Why AI-Built Apps Break

AI coding tools produce functional-looking code quickly, but they lack context about production demands. The result is a codebase that works in demos but fails when real users push boundaries:

  • No error handling — happy-path code that crashes on unexpected input
  • Security gaps — missing authentication, exposed API keys, unvalidated user input
  • No tests — zero coverage means every change risks breaking something else
  • Coupled architecture — everything depends on everything, making isolated fixes impossible
  • Performance issues — unoptimised queries, missing caching, and memory leaks under load

What We Fix

Critical Stabilisation

Stop the bleeding first. We identify the failures causing user-facing outages — broken authentication, data corruption, crashed servers — and ship fixes within days, not weeks.

Security Hardening

AI tools routinely skip input validation, expose internal endpoints, and store secrets in client code. We perform a full security audit and remediate vulnerabilities before they become breaches.

Architecture Remediation

We untangle spaghetti code into maintainable modules. This means adding proper separation of concerns, extracting shared logic, and making the codebase testable — without a full rewrite.

Performance Triage

If your app is slow or timing out under load, we profile the actual bottlenecks (not guesses) and ship targeted fixes: query optimisation, caching, connection pooling, and lazy loading.

Test Coverage

We add automated tests around the critical paths so future changes don't reintroduce old bugs. CI/CD pipelines ensure nothing deploys without passing the test suite.

Our Rescue Process

We don't start by rewriting your app. We stabilise it, then improve it incrementally:

1. Triage (1–3 days) — we review the codebase, identify critical failures, and deliver a prioritised fix plan with honest effort estimates.

2. Stabilise (1–2 weeks) — ship fixes for the issues causing real user pain. Deploy monitoring so you can see the improvement in real time.

3. Harden (2–4 weeks) — security audit, test coverage, performance fixes, and architecture improvements that make the codebase maintainable.

4. Maintain — optional ongoing support to keep the application healthy, handle updates, and prevent regression as you add features.

When to Rescue vs. Rebuild

Not every app is worth saving. We'll tell you honestly:

We provide a clear recommendation with cost and timeline comparisons for both paths.

  • Rescue when the core logic works but the implementation is brittle — most AI-built apps fall here
  • Rebuild when the architecture fundamentally cannot support your requirements (e.g., real-time features on a batch-processing foundation)

Technologies We Rescue

React, Next.js, Node.js, Python, Django, FastAPI, Express, PostgreSQL, MongoDB, Firebase, Supabase, Vercel, AWS, and more. If AI tools can generate it, we can fix it.

Stop Losing Users to Bugs

Your users don't care how the code was written — they care that it works. Tell us what's broken and we'll deliver a triage report within 48 hours.
