Built it with Bolt? Find the keys and the open doors first.
Bolt turns a prompt into a deployed, full-stack app in minutes. What it doesn't do is pause to ask who should be allowed to do what — so the gaps land in the same places every time. A Defuse review finds them while they're still cheap to close.
Where Bolt apps tend to be exposed
- Keys baked into the bundle. API keys for AI, email or payments sitting in the front-end code, where anyone who opens the browser tools can read them and spend on your account.
- API routes with no guard. Endpoints that do real things — read data, run a paid call, change a record — without checking who's asking.
- The client trusted to behave. Prices, user IDs and permissions taken from the browser as fact, so changing them in the browser changes what the server does.
- CORS left wide open. The backend set to accept requests from anywhere, so another site can act in your users' names.
- No validation on the way in. Whatever the form sends is what the database stores — malformed, oversized, or malicious.
None of this means Bolt is the wrong choice. It means the review is worth doing — these are defaults and omissions, not deep flaws, and they're fixable.
You've already done the hard part.
You worked out what the product should do, and real users proved you right. That's the part that takes judgement, and it's yours. What's left is engineering — making the thing you designed safe, solid and able to grow — and that's a known quantity, not a mystery. The point of a review isn't to take Bolt away; it's to let you keep building fast without the nasty surprise.
What a Defuse review gives you
- A findings report, ranked by real-world risk, in plain English with the technical detail underneath
- A Keep / Fix / Rebuild verdict, with the reasoning shown
- A remediation plan your AI tool can actually follow
- A 45-minute walkthrough call
It's a fixed £950, and you own the report — you can take it to any developer. Most Bolt apps start and finish with Defuse; where a finding needs closing, that's the next step, not a precondition.
