SigNoz
Open-source observability platform built on OpenTelemetry, covering APM, logs, traces, and
SigNoz is an OpenTelemetry-native observability platform that brings traces, metrics, logs, exceptions, LLM telemetry, alerts, and dashboards into a single workspace. It is designed to help teams move from symptoms to evidence by correlating signals, such as linking a latency spike to related traces, logs, metrics, and spans, without stitching together separate tools. SigNoz can be used as a managed cloud service or self-hosted on your own infrastructure.
Core capabilities include APM with P99, Apdex, database and external call analysis; columnar log search with trace correlation; trace analysis; threshold, anomaly, and Apdex alerts; LLM observability for OpenAI, Azure OpenAI, Gemini, OpenRouter, LiteLLM, and agent telemetry; infrastructure monitoring for Kubernetes, hosts, and cloud metrics; and reusable dashboards. It supports query builder, PromQL, and ClickHouse SQL, and integrates with Slack, PagerDuty, Opsgenie, MS Teams, email, and webhooks. An MCP server and Noz AI teammate provide agent-native telemetry access.
SigNoz is aimed at teams that need correlated observability across applications, infrastructure, and AI workloads. Pricing is usage-based, with no per-host or per-user charges. A free trial is available, alongside a Teams plan with a monthly minimum that includes usage, and an Enterprise edition offering dedicated cloud, bring-your-own-cloud, or self-hosted deployment with compliance and support options.
