SigNoz is a full-stack observability platform with over 26,000 GitHub stars that brings metrics, distributed traces, and logs into a single, correlated view. Built natively on OpenTelemetry — the CNCF standard for instrumentation — it eliminates the fragmentation of running separate tools for each telemetry signal. The platform uses ClickHouse as its storage backend, a columnar database optimized for analytical queries, which delivers fast query performance even over massive volumes of observability data without the operational complexity of maintaining separate Prometheus, Elasticsearch, and Jaeger clusters.
The platform provides application performance monitoring with service maps that visualize request flows, latency percentile tracking (P50/P90/P99), error rate dashboards, and database call analysis. Distributed tracing supports flame graphs for debugging slow requests across microservices, while the log management system offers full-text search with attribute-based filtering. Alerts can be configured on any metric, trace, or log pattern with notification channels including Slack, PagerDuty, and webhooks. Custom dashboards with a drag-and-drop builder let teams create views tailored to their specific infrastructure.
SigNoz addresses a significant cost concern in observability: enterprise platforms like Datadog charge per host, per custom metric, and per GB of logs ingested, leading to unpredictable bills that can reach tens of thousands of dollars monthly. As an open-source, self-hosted solution, SigNoz has no per-host or per-metric pricing — you pay only for the infrastructure you run it on. For teams already using OpenTelemetry for instrumentation, SigNoz is a natural backend choice. It also offers a managed cloud tier for teams that prefer not to operate ClickHouse and the associated infrastructure themselves.
