SigNoz

With over 31,000 GitHub stars and native OpenTelemetry support that eliminates vendor lock-in from day one, SigNoz delivers full-stack observability covering metrics, traces, and logs in a single pane of glass without the per-host pricing model of commercial APM platforms. The platform ingests telemetry data through the OpenTelemetry Collector, supporting auto-instrumentation for Java, Python, Node.js, Go, Ruby, PHP, and .NET applications with zero code changes required for basic tracing. ClickHouse serves as the columnar storage backend, providing fast aggregation queries over billions of spans and log lines with configurable retention policies and tiered storage. The distributed tracing view renders flame graphs and Gantt charts showing request flow across microservices with latency breakdowns, error rates, and p99 percentile calculations. Custom dashboards support PromQL and ClickHouse SQL queries with time-series charts, bar graphs, tables, and value widgets. The log management pipeline supports structured and unstructured logs with full-text search, log pipelines for parsing and enrichment, and correlation with traces via trace IDs. Alert rules can be configured on any metric or log query with notification channels including Slack, PagerDuty, OpsGenie, webhooks, and email. The exceptions monitoring module automatically groups and tracks application errors with stack traces, occurrence counts, and first-seen timestamps. Service maps visualize inter-service dependencies with real-time latency and error rate overlays. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed with an enterprise edition available.

Benefits

  • Unified Metrics Traces and Logs
  • Monitor application performance with distributed tracing, infrastructure metrics, log management, and exception tracking in a single platform, eliminating the need to maintain separate observability tool stacks.
  • Native OpenTelemetry Without Vendor Lock-In
  • Built from the ground up on OpenTelemetry standards, SigNoz accepts telemetry data from any OTel-compatible source, ensuring your instrumentation investment remains portable across observability platforms.
  • ClickHouse-Powered Fast Queries
  • Columnar storage with ClickHouse enables sub-second aggregation queries over billions of data points, configurable retention policies, and efficient compression reducing storage costs compared to Elasticsearch-based alternatives.
  • Predictable Self-Hosted Pricing
  • Eliminate per-host and per-GB pricing surprises by running on your own infrastructure with unlimited data ingestion, unlimited users, and no feature gates behind enterprise paywalls for core observability capabilities.
