Kubernetes-native alerting — open-source core, hosted UI for teams.

What it does well

  • Enriches Prometheus alerts with logs and diagnostics directly in Slack notifications.
  • Core functionality is open-source and runs inside your Kubernetes cluster.
  • Offers a free tier for small teams and individual use via its hosted UI.

Where it falls short

  • Primarily an alert-enrichment tool, not a standalone observability or APM platform.
  • Effectiveness is highly dependent on a well-configured underlying Prometheus and Alertmanager setup.
  • As a newer tool (founded 2021), its feature set is less broad than more established competitors.
