About SigNoz
SigNoz is an open source observability platform for monitoring applications, services, and infrastructure. It brings logs, metrics, and traces into one place so you can spot issues, troubleshoot downtime, and debug with richer context, positioned as an open source alternative to Datadog and New Relic.
Instrumentation is based on OpenTelemetry, covering application performance monitoring, centralized log management, distributed tracing, metrics dashboards, alerts, exception monitoring, and LLM observability. Signals are correlated across logs, metrics, and traces, with a query builder, PromQL and ClickHouse queries, and dashboard panels like time-series, bar, and pie charts.
SigNoz follows an open-core model: the community edition is MIT-licensed and self-hostable with Docker or Kubernetes Helm, while SigNoz Cloud and managed deployments are offered commercially. It supports every language OpenTelemetry does, including Java, Python, JavaScript, Go, .NET, Ruby, Rust, and more.
