WHAT IS IT?
SigNoz is an open-source observability platform that brings logs, metrics and traces together in a single interface. Built natively on OpenTelemetry and powered by ClickHouse, it positions itself as a self-hostable alternative to Datadog or New Relic — without the licensing cost or vendor lock-in.
WHY IS IT INTERESTING?
- Three pillars unified: logs, metrics and traces correlated in one place, giving you far richer debugging context than scattered tools.
- OpenTelemetry-native: an open standard for instrumentation, so no dependency on a proprietary agent and full portability of your data.
- ClickHouse under the hood: blazing-fast search and aggregation on high-cardinality data, the same engine used by Uber and Cloudflare.
- APM out of the box: ready-made charts for p99 latency, error rates, Apdex scores and operations per second.
- Self-hostable and cost-effective: you keep control of your data and avoid bills that explode with volume.
USE CASES
- Monitor a microservices architecture with distributed tracing (flamegraphs, Gantt charts).
- Centralize application logs with fast search and aggregation via ClickHouse.
- Set up alerts and anomaly detection on production services.
- Track observability for LLM applications, including token usage.
- Replace a costly Datadog/New Relic stack with a self-hosted solution.
