I started building Zaxion in August 2025. No co-founder. No team. No funding. Just me, a CS The idea was simple: what if your team's standards 8 months later I shipped it. Zaxion is a GitHub App that enforces custom code The engine uses Babel AST to understand code After I shipped it,** I wanted to prove it worked on **So I ran it on 5 of them. cal.com is one of the most well-known open source Zaxion found console.log statements shipping to markdownToSafeHTMLClient.ts at line 15. 2 occurrences. Production code. Not a test file. Console logs in production mean internal application It did. Zaxion caught it. tRPC is the TypeScript RPC framework that half the Zaxion found 5 unhandled async calls in packages/react-query/src/utils/createUtilityFunctions.ts Production utility code.

Different repo. Different team. I want to be clear about something. I'm not posting these findings to make these teams These are what happens when good engineers review That's the gap Zaxion sits in. It doesn't get tired. It doesn't have a bad day. It runs the same check on every PR the same way You install Zaxion on your GitHub repo as a GitHub You either use the 31 built-in policies that ship When a PR opens, Zaxion analyzes it and either That's it. I'm going to be straight with you. Zaxion is real and it works. t*he findings above * but it's also something **I built alone some policies might be too aggressive for certain I'm not asking you to use a broken tool. if you install it and something doesn't work the if a policy fires when it shouldn't — tell me. this is the stage where real feedback from real It's completely free for open source projects.
