What is Sentinel's Kubernetes FinOps dashboard?

Open source tool tracking costs, waste, health in K8s clusters — now with forecasts and smart layouts, built iteratively.

Does Sentinel auto-fix Kubernetes waste?

Not yet — forecasts and alerts, but no actuators. Actions manual for now.

Is Sentinel ready for production?

0.x with no auth? Testbed only. Production needs hardening.

How does Sentinel forecast costs?

Pure Go linear regression on historical data, with confidence bands — simple, dependency-free.
