SigNoz

What is SigNoz?

Observability platform with logs, metrics, traces and alerts in one place, built on OpenTelemetry.

Who is SigNoz best for?

SigNoz is best for engineering teams on OpenTelemetry who want logs, metrics and traces in one self-hosted tool.

• Leaving a stack of separate tools

  Logs, metrics, traces, alerts and dashboards sit in one place, so a slow endpoint leads straight to its traces and logs.

• OpenTelemetry users

  It is built on OpenTelemetry, so you instrument once with open standards and keep your telemetry portable.

• LLM and agent apps

  It traces prompts, tool calls, tokens, latency and cost next to application and infrastructure data.

• Teams that want predictable bills

  SigNoz Cloud has no per-user or per-host pricing, and the self-hosted edition has no licence fee.

How much does SigNoz cost?

SigNoz's Community edition is free to self-host; SigNoz Cloud starts at $49 a month, which includes $49 of usage, then charges $0.30 per GB of logs or traces and $0.10 per million metric samples.

Teams has a 30-day free trial with no card and data centres in the US, EU and India. Logs and traces keep 15 days and metrics one month by default; longer retention costs more per GB. Noz, the AI assistant inside SigNoz, is only on SigNoz Cloud. Enterprise offers annual contracts with volume pricing. Full pricing on signoz.io. We checked these prices on 8 Nov 2026.

What are the best SigNoz alternatives?

SigNoz is an open source alternative to Pydantic Logfire, Middleware and Dash0. Grafana Loki, AgentOps and Grafana do the same job and are open source too.

Pydantic LogfireFree

One trace across model calls, agents, APIs and database queries.

MiddlewareFree

Full-stack observability with an AI SRE agent.

Dash0Freemium

Logs, metrics and traces unified, OpenTelemetry-native.

Grafana LokiOpen Source

Log aggregation system that indexes labels rather than full text, so large log volumes stay cheap.

AgentOpsOpen Source

Trace, debug and cost-track your AI agents in production.

GrafanaOpen Source

Charts metrics, logs and traces from Prometheus, SQL databases and 150+ other data sources.
