Grafana Tempo vs SigNoz

Grafana Tempo has no write-up on Specifiction yet; its figures are above.

SigNoz is an open-source observability tool for monitoring applications and infrastructure. It brings logs, metrics, traces, and exceptions together with alerting and separate explorers for Trace, Logs, and Metrics. The OpenTelemetry-native design does not require proprietary agents. A Query Builder supports aggregations, filters, and formulas across signal types, while alerts can detect thresholds, anomalies, and Apdex conditions. Users can create dashboards from metrics, logs, and traces. APM charts cover p99 latency, error rate, Apdex, and operations per second, alongside database and external-call monitoring. Distributed tracing uses flamegraph and Gantt-chart views to follow requests across services. SigNoz stores telemetry in ClickHouse with hot and cold tiers. It can run in the cloud or be self-hosted using Docker, Docker Swarm, or Kubernetes. Cloud provides 30-day access to all features for new users; the self-hosted Community option is free but requires users to manage infrastructure, storage, scaling, upgrades, and backups.
