Hey Product Hunt! 👋 I’m Kishan, creator of LastGood. If you’ve ever been on a Sev-1 incident call at 2 AM, you know the drill: everyone is looking at a latency spike on a dashboard, checking logs, and asking "Who deployed recently? Did someone toggle a feature flag? Did the Kubernetes cluster update?" It takes 20-30 minutes just to isolate the culprit change. We built LastGood to fix this. It acts as the change correlation layer for your stack. By connecting to your telemetry (Datadog, Prometheus) and your deployment pipelines (GitHub, LaunchDarkly, Helm/Kubernetes), LastGood maps alerts directly to code & infrastructure mutations in 3 seconds. It doesn't just show you what broke; it generates the exact remediation commands (like /rollback --commit a1b2c3d or /flag disable) to get you back to your Last Known Good state. How to try it: Check out our landing page: lastgood.space (which features our correlation scenarios in action!) Sign up for the console or query our Rewind API. We are in public beta and would love to hear your feedback: What telemetry/incident tools do you use most? What custom integrations (e.g., Terraform, Ansible) should we support next? I’ll be here all day to answer your questions and chat about incident response! — Kishan
