Signoz

Open-source observability platform that unifies logs, metrics, traces, dashboards, and alerts in a single application. Built from the ground up on OpenTelemetry, enabling vendor-free instrumentation and avoiding proprietary agent lock-in.

SigNoz is trusted by teams across early-stage startups to public enterprises, used in deployments spanning five continents. It differentiates from Datadog and New Relic as an OpenTelemetry-native alternative: OTel-first documentation, semantic convention correlation, and span-based events for richer debugging context. The ingestion engine handles large-scale workloads with ClickHouse as the columnar datastore for fast querying.

Key capabilities:

• Logs, metrics, traces, exceptions, and LLM observability in one platform
• OpenTelemetry-native with best-in-class semantic convention support
• ClickHouse-backed storage for high-performance querying at scale
• Self-hosted, cloud, or managed deployment options
• Alerts on any telemetry signal with configurable thresholds and notification channels
• PromQL, ClickHouse queries, and DIY query builder for flexible analysis

Platform teams use SigNoz for application performance monitoring, distributed tracing across microservices, and centralized log management. Instrumentation via OpenTelemetry SDKs, collector agents, or binary deployment keeps the codebase vendor-free while supporting 50+ data sources. Debugging workflows benefit from correlated logs, metrics, and traces and from flamegraphs and Gantt charts for request flow visualization.
