What it does
SigNoz is an observability platform with self-hosted and managed-cloud options. It combines logs, metrics, traces, and exceptions, with explorers and alerts for investigating application behavior. The Cloud quickstart sends telemetry from a demo application to an account, while teams that prefer to operate the service themselves can use the Community installation path.
Follow a sample request across signals
The Cloud quickstart asks for a SigNoz account, Docker, and Docker Compose, then uses a small OpenTelemetry demo application to send traces, logs, and metrics to the account. The docs say the sample can be started without changing application code, which is useful for seeing the three signals together before instrumenting a production service. Teams can instead self-host through the documented Docker or Kubernetes path. At the time checked, the pricing page listed $49 per month including $49 of usage, logs and traces at $0.30 per ingested GB, and metrics at $0.10 per million samples. It listed 15 days of logs and traces retention and selectable metrics retention. The page text also shows a $199 figure beside the $49 price without clarifying their relationship or any offer terms. The repository's root license covers code outside ee/ and cmd/enterprise/ under MIT Expat; those enterprise directories use a separate license requiring an agreement for production use. Check which features a deployment needs before selecting a self-hosted path.
Strengths
- The platform brings logs, metrics, traces, and exceptions into one observability workflow.
- The Cloud quickstart sends demo telemetry without requiring changes to an existing application.
- The current pricing page lists signal-specific usage rates and retention options.
Watch out for
- Self-hosting transfers installation, storage, upgrades, and availability work to the operator.
- Cloud usage costs depend on telemetry volume, and enterprise self-hosted directories have separate production license terms.
Best for
- Debugging application behavior across logs, metrics, and traces
- Evaluating OpenTelemetry observability with a sample application
