Overview
SigNoz is an open-source observability platform. Logs, metrics, and traces in one tool. OpenTelemetry-native. Datadog/New Relic alternative with self-hosting.
Pros
- All three signals (logs, metrics, traces)
- OpenTelemetry-native
- ClickHouse backend (fast queries)
- Unified UI for all signals
- Self-hosted option
- Alert management built in
Cons
- Self-hosting needs significant resources
- Smaller ecosystem than Datadog
- Dashboard builder less mature
- Learning curve for ClickHouse
- Enterprise features behind paid tier
Verdict
SigNoz is the most complete open-source observability platform. Having logs, metrics, and traces in one tool with a unified UI eliminates the context-switching that makes multi-tool observability stacks frustrating. The OpenTelemetry-native approach means you're not locked into a proprietary agent, and the ClickHouse backend handles the query volume that makes other open-source tools slow.
