Rules are organised into business groups with team permissions and managed through the UI and API, alongside your existing collectors and Grafana dashboards. You can inspect rule evaluations, event history and notification results, and deliver to Slack, PagerDuty and other tools. Includes a built-in AI agent and an MCP server, and a Docker Compose evaluation stack. ★~13.4k.","theCatch":"Much of its community and older documentation is in Chinese. It is a separate alerting system next to Alertmanager or Grafana alerting, so pick one as your source of truth. The built-in AI features need your own model provider.","verdict":"A strong central alerting layer for teams with many data sources.","addedAt":"2026-10-18","featured":false,"domain":"Observability","subSpecialty":"Observability","subcategory":"Observability","tags":["self-host","permissive","observability","active"],"capabilities":[],"surfaces":["Self-host"],"ecosystem":["Multi-platform"],"licenseModel":"Apache-2.0","githubStars":13366,"starsPerWeek":39,"access":"free","archived":false,"repo":{"createdAt":"2020-03-03","pushedAt":"2026-10-15","license":"Apache-2.0","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"sentry","name":"Sentry","tagline":"Error tracking that actually helps"},{"slug":"grafana","name":"Grafana","tagline":"Dashboards for everything observable"},{"slug":"prometheus","name":"Prometheus","tagline":"Time-series metrics for cloud-native"},{"slug":"opentelemetry","name":"OpenTelemetry","tagline":"Vendor-neutral observability framework"},{"slug":"datadog","name":"Datadog","tagline":"Unified observability platform"}],"links":{"self":"/api/gems/nightingale","html":"/gems/nightingale","markdown":"/gems/nightingale.md","category":"/api/gems?category=observability","categoryPage":"/stacks/observability"}}
