SigNoz is built OpenTelemetry-first: send OTLP, get traces, metrics, and logs in one UI. ClickHouse under the hood, which makes it cheap to self-host at scale.
Pick it if: you want one tool to replace APM + logs + traces and you’re willing to run ClickHouse.
Skip it if: you want a single binary (SigNoz is a stack: ClickHouse + Zookeeper + query service + frontend).
Deployment: docker-compose for dev, Helm chart for k8s. Docs are solid.
