Strix (usestrix/strix) hit #1 on GitHub Trending on July 3, 2026 with +2,137 stars in a day — 32.8k total, Apache 2.0. It runs autonomous AI agents that act like real hackers: they exploit your app, validate each finding with a working proof-of-concept, and file only bugs they actually broke. On the XBEN benchmark it solved 100/104 web challenges (96%) at ~$3.37 each. This is the builder\'s read — what it is, how to install and run it, whether it hallucinates, how it stacks up against XBOW and PentAGI, when to skip it, and exactly how I\'d wire it into a real MVP\'s CI pipeline without it torching your API budget.
