SigNoz

SigNoz is an open-source observability platform, founded by Pranay Prateek and Ankit Nayan, that unifies metrics, traces, and logs on a single OpenTelemetry-native backend. Because it ingests data through OpenTelemetry, teams instrument once and avoid vendor-specific agents, then query all three signals in one interface. SigNoz can be self-hosted for full control of telemetry data or run as a managed cloud, which gives teams an alternative to closed observability suites without giving up correlated traces, metrics, and logs. Because the backend is one system, an engineer can pivot from a slow trace to the related logs and metrics without switching tools.

Key Capabilities:

• OpenTelemetry-native ingestion for metrics, traces, and logs

• Distributed tracing with service maps and latency breakdowns

• Metrics dashboards and alerting on application and infrastructure signals

• Log management correlated with traces in one interface

• Self-hosting for full ownership of telemetry data

• A columnar store tuned for high-volume observability queries
