Fabraix

Fabraix is an advanced adversarial verification platform built specifically for AI agents and multi-agent systems, created by ex-Meta engineers. When your agents handle real users, subtle reasoning gaps and hidden vulnerabilities can slip past traditional testing, and Fabraix is designed to surface them early.

At its core is Nyx, a dedicated adversarial staging environment that launches over 1,000 automated strategies to stress-test your AI systems across security, logic, and alignment. Unlike conventional software testing, Fabraix takes a pure blackbox approach that adapts in real time to how your agent actually behaves, helping you uncover reasoning gaps, prompt injections, and reward hacking before they ever reach production.

Fabraix works across text, voice, and browser-based interactions, and integrates directly into your CI/CD pipelines so every release gets continuous safety coverage without slowing your team down.
