Hi HN! I built PR Cat after getting frustrated with engineering metrics tools that create more problems than they solve. You know the type - mysterious "efficiency scores," individual performance tracking, and black-box algorithms that pit developers against each other. PR Cat takes a different approach: it measures team health metrics (cycle time, PR size distribution, review coverage, work distribution) with complete transparency. Every calculation is visible, it's self-hosted so your data stays yours, and it's MIT licensed. One team using it discovered they were spending 60% of their time on bugs vs their planned 20%. Instead of blame, this led to investing in better testing infrastructure. Six months later, bug time was down to 25%. Built with Next.js + TypeScript, uses AI for PR categorization (but you can see/modify the prompts), and deploys easily on Vercel. Looking for feedback from teams tired of surveillance metrics. What metrics actually help your team improve?
