We catch and diagnose the bug. You keep control of the code.
Flinteye runs your product like a real user, proves every bug with an Evidence Pack and hands you a patch to review. It never commits, merges or edits your code.
Built for every product where an edge case costs money.
A valid IBAN is rejected on payout
The agent enters real formats from your domain rules and finds the one your validator refuses.
Start free auditA diagnostician, not another committer.
- Coding agents
- Write into your repository and ask you to trust the merge.
- Test scripts
- Break whenever the interface changes, and someone has to rewrite them.
- Flinteye
- Finds the bug, proves it, proposes a diff. No code lock-in, no auto-merge, your team owns every line.
Every bug arrives with proof.
Each finding ships as an Evidence Pack: what the agent did, what the browser saw, why it broke, and a patch to review.

Chaos Personas
The Rapid Clicker, the Invalid Data Inputter and the UX Friction Inspector behave like real users on a bad day.
Domain training, near-zero cost
Your docs, API specs and industry rules are embedded once. When the agent meets an unknown rule, such as a regional tax or IBAN format, it looks it up live.
