SigNoz

SigNoz brings traces, metrics and logs together in one full stack observability platform built on OpenTelemetry, storing them for search, dashboards and alerts. Because it speaks OpenTelemetry natively, pointing your existing exporters at it is often enough to get correlated views, service maps and a trace explorer without rewriting instrumentation.

Teams use it to follow request latency, error rates and infrastructure health in one place, covering monitoring, log search and alerting that normally means three tools.

Self hosting keeps traces and log contents private, avoids the per host and per user pricing of hosted vendors, and gives you a datastore you back up like any other database.
