Show HN: Kaval – catch silent regressions CI and review miss, your Git history

Category: devtools

Tags: regression-detection, ci-tools, code-review

Score: 6.8/10 (Innovation: 7, Technical: 6, Documentation: 7, Utility: 7)

Kaval is a pre-merge gate that detects silent regressions by running both the old and new versions of code on the same inputs and showing behavior divergence that traditional CI and code review miss. Its innovative approach of executing and diffing behavior rather than static analysis fills a known gap for catching subtle bugs, though the core engine is hosted and not fully open-source.

Target audience: backend devs, devops, software engineers
