Summary

Strix is a free tool that acts like a real attacker on your vibe coded app, finding security holes and handing you the exact fix. It replaces the manual verification step most builders skip, and it costs a few dollars to run on your own model key instead of thousands from a security firm.

Core ideas

One context card plus 8 ideas

Behavioral testing over code scanning: A normal scanner just reads your code and flags anything that looks risky. Strix actually logs in, clicks around, and tries to reach places it shouldn't, which is a completely different test.
Finds real world exploits: It catches things like a page where one customer can see another customer's data, the exact kind of bug that normally surfaces through an angry email instead of a report.
Comes with a patch, not just a warning: Strix returns the exact steps that broke the app plus a patch you can apply, so there's nothing left for you to manually verify.
Runs on your own infrastructure: It installs on your machine and runs using your own model key, so you control the cost and the environment.
Cheap compared to hiring a firm: A run costs a few dollars instead of the thousands security firms typically charge for this kind of testing.
Spend cap matters: Since it runs on your own key, setting a spend cap flag before the first run keeps costs predictable.
Give it time to work: The first run should be given an evening, not a quick five minute check.
Ownership is a legal boundary: Point it only at apps you own. Running it against someone else's site is a crime.
