Open Source Metrics, Traces and Logs in a single pane of glass

SigNoz offers an open source observability platform replacing multiple tools by providing a single pane for metrics, traces and logs. It is built on OpenTelemetry, uses ClickHouse for fast aggregations, and can be self-hosted; the launch highlights community metrics, a product demo, and asks for feedback from developers.
