SigNoz/signoz

SigNoz is an open-source, OpenTelemetry-native observability platform for your team and their AI agents. Get logs, metrics, and traces in one tool with features like APM, distributed tracing, log management, infra monitoring, etc. Combined with SigNoz MCP and a native AI teammate (in SigNoz Cloud) it helps you build more resilient apps.

What it solves

SigNoz is an open-source observability platform that replaces fragmented monitoring stacks. It provides a single place to manage logs, metrics, traces, alerts, and dashboards, allowing teams to debug production issues faster by correlating these different signals.

How it works

Built on OpenTelemetry, SigNoz uses a single columnar database designed for high-cardinality and high-volume observability workloads. It allows users to instrument their applications and infrastructure using open standards, ensuring they maintain ownership of their telemetry data.

Who it’s for

Engineering teams and DevOps professionals who need a comprehensive monitoring solution for their applications, Kubernetes clusters, and AI/LLM applications, particularly those moving away from single-purpose tools or commercial platforms with unpredictable pricing.

Highlights

  • LLM and AI Observability: Specifically traces LLM apps, RAG pipelines, prompts, tool calls, tokens, and costs.
  • Correlated Signals: Seamlessly move between service charts, traces, logs, and infrastructure metrics without switching tools.
  • Agent-Native Observability: Includes an MCP server to bring telemetry into coding agents and an AI assistant (Noz) for investigating incidents.
  • OpenTelemetry-native: Uses open standards for instrumentation to avoid vendor lock-in.
  • Infrastructure Monitoring: Full visibility into Kubernetes pods, nodes, and host-level resources (CPU, memory, disk, network).
  • Distributed Tracing: Features flamegraphs, waterfalls, and trace funnels to analyze request flows and drop-offs.
