Show HN: Why it's hard to know which deployment caused a production incident (github.com)

4 points by veinar_gh ↗ HN
We’re a team of two building Valiant after too many incidents where “something changed” but nobody could tell what actually caused production issues.

Valiant correlates intent (Git commits, CI/CD signals) with actual execution (Kubernetes rollouts) and links them to Prometheus metrics, so you can see the real impact of each change - not just what was deployed.

It’s open-source, still under active development, and very much a work in progress. Feedback, ideas, or contributors are welcome.

No website yet — just the GitHub repo ;)

Nice. The "5 deploys in one hour, which one broke it?" scenario is painfully common. We deal with this weekly. One thing I'd love to see: integration with PagerDuty/OpsGenie so that when an alert fires, it could automatically surface the ranked list of suspect changes.
