Karma is the dashboard that Alertmanager’s built-in UI should have been. It aggregates alerts from multiple Alertmanager clusters into a single pane, with grouping, filtering, color-coding, silence creation, and acknowledgment in one view.
Pick it if: you have more than one Alertmanager (production, staging, multi-region) and the native UI’s lack of cross-cluster aggregation is hurting on-call response. Also pick if you want a richer silence-management UX than the upstream Alertmanager UI offers.
Skip it if: you have a single Alertmanager and the bundled UI is sufficient — Karma is an additive layer, not a replacement. Also skip if your team operates entirely inside Grafana; recent Grafana versions have an integrated Alertmanager view that may overlap.
Deployment: single Go binary or Docker container. Helm chart community-maintained. Configuration is a YAML file pointing at one or more Alertmanager endpoints.
