What is it?

SigNoz is an observability platform built on OpenTelemetry. It collects logs, metrics and distributed traces and lets teams correlate them in one interface, so a developer can move from a slow service chart to the trace behind it and the related logs without switching tools.

The project covers APM views such as latency, error rate and throughput, log search and aggregation with a visual query builder, dashboards queried with PromQL or ClickHouse SQL, Kubernetes and host infrastructure monitoring, and trace funnels. It also includes LLM observability for tracing prompts, tool calls, tokens and costs.

SigNoz can be self-hosted with Docker, Kubernetes or Linux, and a managed SigNoz Cloud version is also offered. The project is written in TypeScript with a Go backend, and it is designed around a single columnar database for high-cardinality data.

Key features

  • 01Unified logs, metrics, traces and alerts in one interface
  • 02APM views for service latency, error rate and throughput
  • 03Distributed tracing with flamegraphs, waterfalls and trace funnels
  • 04Log search and aggregation with a visual query builder
  • 05Dashboards queried with PromQL or ClickHouse SQL
  • 06Infrastructure monitoring for Kubernetes clusters and hosts

Use cases

  • Debugging slow or failing requests across microservices
  • Replacing a stack of Prometheus, Jaeger and separate log tools with one platform
  • Monitoring LLM applications for token usage, latency and cost
  • Self-hosting an observability backend built on OpenTelemetry

Quick start

  1. 1

    Open the self-hosting install guide

  2. 2

    Install with Docker (see Docker install docs)

  3. 3

    Or use Foundry, the self-host tool linked in the README

Things to know

  • The license is listed as NOASSERTION, so check the repository license terms before use.
