Flinteye

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.

Sample finding

A valid IBAN is rejected on payout

The agent enters real formats from your domain rules and finds the one your validator refuses.

+ if (!isValidIban(iban)) throw invalid("iban")

A diagnostician, not another committer.

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.

Set up in five minutes

A URL and test credentials. No SDK to install and no scripts to maintain.

Security guardrails

OWASP-style XSS and SQL injection probes, a read-only staging mode that blocks every write request, and PII masking in every report.
