About diffray
AI Code Review That Developers Actually Trust
Built by engineers with 15+ years in payment security
Our Story
Developers were ignoring AI code reviews, and we understood why. The existing tools had fundamental problems:
Too Much Noise
18 comments per PR, only 2 actually read
Missing Real Issues
Flags style nitpicks while missing critical bugs
No Memory
No recollection of team decisions or past reviews
Low Confidence
Uncertain findings presented as facts
We knew there had to be a better way.
Our Mission
To make AI code review deterministic, reliable, and trustworthy
We believe AI code review should be something you can truly rely on. Not random suggestions that change with every run, but consistent, predictable analysis that becomes an integral part of your development workflow. When diffray flags an issue, you can trust it's real and actionable.
