Fairy Scout reads every PR
before you merge.
Specialized AI agents hunt the bugs AI tools ship — across code, security, data science, infrastructure, legal, financial, and clinical work. A skeptic strips out false positives. You get a review of what's real, and what only a human can sign off on.
10 free reviews / month · then Scout Pro $29/mo · or a human Fairy from $499
Under the hood
Four agents. Genuine signal.
Two specialists find issues in parallel, a skeptic kills the false positives, and a converter writes the review. Real signal beats a noisy bot every time.
The Hunter
Security + integration — webhooks without signature checks, exposed keys, missing RLS, auth bypasses, duplicate-charge bugs.
The Analyst
Logic + architecture — unhandled nulls, race conditions, float-for-money, N+1 queries, missing error handling.
The Skeptic
Challenges every finding and removes false positives before they reach your PR. A Scout that cries wolf gets ignored.
The Converter
Writes a clean GitHub review of what's real, what's uncertain, and what only a human can sign off on.
Scout finds. A Fairy signs off.
Scout checks known AI-failure patterns — fast, free, every PR. It is not a guarantee: it can't catch novel vulnerabilities, business-logic errors, or integration edge cases it doesn't know to look for. When the stakes are real, a senior Fairy engineer reviews what Scout can't and takes responsibility for the result.
Critical found
Scout flags real bugs + what it can't evaluate. Fix before merge — a Fairy verifies.
Uncertain
Scout sees patterns it can't fully resolve. A human knows.
Clean
Nothing in Scout's library. Not a sign-off — get a Fairy for the guarantee.
