Authorization security for AI-built apps

Tell us who should see what. We try to break those rules.

SickHaxx tests your deployed app for real authorization failures, gives your coding agent the context to fix them, and keeps testing after every deployment.

Free public-surface scan. No signup required. Verify ownership for deeper testing.

An automated security assessment, not a generic checklist.

Every finding is reproducible, tied to your authorization contract, and verifiable with a single replay.

๐Ÿ”

Public-surface scan

Fingerprint your framework, hosting provider, and exposed configuration โ€” no signup needed.

๐Ÿ›ก๏ธ

Authorization contract

Define who should read, write, update, or delete what. We turn your rules into an executable test.

๐Ÿงช

Alice vs. Bob testing

We test as anonymous, a normal user, and an elevated role to find cross-user breaches.

๐Ÿง 

MCP diagnosis

Your coding agent retrieves the exact root cause, the affected policy, and a reviewable fix plan.

โœ…

Replay verification

We mark a finding fixed only after the exact exploit no longer works.

๐Ÿ”„

Continuous regression

A deployment or GitHub check reruns your contract and blocks critical regressions.

From URL to fixed finding in one loop

1

Observe

Paste your app URL. We fingerprint and inventory its surfaces.

2

Define

Capture who should see what in plain English. We build a contract.

3

Test

We attack the contract as anonymous, Alice, Bob, and an admin.

4

Diagnose

Your agent pinpoints the RLS policy, route, or config at fault.

5

Verify

We replay the exact test and confirm the fix holds.
