Open source, distributed tracing platform for microservices observability
Jaeger is a CNCF distributed tracing system focused on OpenTelemetry-compatible spans. It lacks built-in logs, metrics, and dashboards. SigNoz extends the same OTel foundation with unified log management, infrastructure metrics, alerts, and a production-ready UI while preserving full open-source freedom.
