Customers leaving quietly
Most users don't file a bug report — they uninstall. Crash rates and slow pages are churn you never get to argue with.
App rescue
Your app is stuck. Let's find out how bad it really is.
A previous vendor went quiet. The app crashes under load. Nobody left on the team understands the codebase. Before anyone proposes a rewrite, you deserve an independent, evidence-based read of what's actually wrong and what it costs to fix.
Sounds familiar?
- Your vendor has gone quiet, slow or defensive
- The app is live but slow, crashing or losing data
- Nobody currently on the team understands the codebase
- Every new feature seems to break two old ones
- You've been told the only option is a full rewrite
- You don't have the repository, the credentials or the documentation
If two or more apply, the discovery call is worth 45 minutes.

Why it matters now
What waiting actually costs
Every one of these gets more expensive the longer it runs. That's the whole argument for acting this quarter rather than next.
Paying twice for the same work
Every month spent patching a system nobody understands is money spent twice: once now, and again in the eventual fix.
A rewrite you may not need
Rewrites are the default recommendation of whoever wants the next contract. Often the real problem is a handful of queries and a missing cache layer.
Our approach
How we solve this
The same path every time, so you always know which step you're on and what it produces.
- 01
Triage call
Free, 30–45 minutes. What's broken, what's urgent, what access exists — and whether this is a stabilisation job or something larger.
- 02
Code & architecture audit
One to two weeks inside the codebase: quality, security, performance, dependencies, test coverage and the actual state of the infrastructure.
- 03
The honest verdict
What's salvageable, what should be rewritten, what it costs either way — written down, with evidence, including the option to walk away from us.
- 04
Stabilise first
Stop the bleeding before adding anything: critical bugs, security holes, the worst performance offenders, monitoring so failures surface early.
- 05
Rebuild or continue
With the product stable, we either resume the roadmap or replace components incrementally — never a big-bang rewrite with the lights off.
What you get
Concrete deliverables
- Written audit of code, architecture and security
- Prioritized issue list ranked by risk and effort
- Salvage-vs-rewrite recommendation, with costs
- Stabilisation pass on critical bugs and bottlenecks
- Monitoring, error tracking and alerting set up
- Recovered access: repos, cloud accounts, credentials
The result
Business outcomes
- 01
An independent second opinion you can act on
- 02
A product that stops getting worse while you decide
- 03
Measured performance improvement, before and after
- 04
Control of your own infrastructure and code again
The way in
Start here, not with a contract
A small, fixed first step that gives you something useful whether or not you continue with us.

App Rescue Audit
An independent diagnosis with no rewrite agenda attached. If the honest answer is that your current team should finish it, that's what the report will say.

See how we deliverWhat people ask in this situation
Straight answers. If yours isn't here, bring it to the call.
Will you just tell us to rebuild it from scratch?
Only if the evidence says so, and the report will show you that evidence. A rewrite is occasionally right, but it's recommended far more often than it's warranted — usually by whoever would be paid to do it.
We don't have access to the code. Can you still help?
Often, yes. Recovering repository, cloud and domain access is a normal first step in a rescue, and we can work from a deployed build to assess the situation while that's in progress.
Our previous developer is still involved. Is this awkward?
It doesn't need to be. Many audits end with a plan the existing team executes — the value is an independent read, not a change of vendor. We can also run it confidentially if you'd prefer.
How fast can you start?
Usually within a week for an audit, and immediately for a genuine production emergency. Tell us on the triage call if something is actively down.
