About SigNoz
What is SigNoz and what problem does it solve?
SigNoz is an open-source, unified observability platform that serves as a cost-effective alternative to Datadog. It helps platform engineering and DevOps teams debug application performance issues faster by correlating logs, traces, metrics, and spans—all in one tool, without the need to switch between separate monitoring solutions. SigNoz eliminates the pain of unpredictable, per-host or per-user pricing by offering simple usage-based billing across logs, traces, and metrics.
Who is SigNoz for?
SigNoz is built for fast-scaling platform teams, SREs, and developers who need full-stack observability with flexible deployment—cloud, self-hosted, or managed in your own cloud. It is ideal for teams seeking open standards (OpenTelemetry) to avoid vendor lock-in. It is not suited for teams looking for a lightweight uptime monitor or a simple logging-only tool; SigNoz is a comprehensive observability suite with APM, distributed tracing, and infrastructure monitoring.
Key use cases and capabilities
Teams use SigNoz to track P99 latency, Apdex scores, database calls, and external service calls per microservice. Its columnar store (ClickHouse) enables fast, high-cardinality queries via query builder, PromQL, or SQL. SigNoz also supports AI agent telemetry by exposing a known OpenTelemetry schema, making it easier for LLMs and agents to debug autonomously. With built-in alerts, dashboards, and trace correlation in logs, SigNoz helps move from a latency spike to root cause in seconds.
