Overview
SigNoz is a one-stop, open-source observability platform built on top of OpenTelemetry, designed to be a modern alternative to Datadog, Grafana, and CloudWatch. It unifies application performance monitoring (APM), logs, distributed tracing, infrastructure metrics, and AI/LLM telemetry into a single, fast, and cost-effective tool. By leveraging a columnar database (ClickHouse) and open standards, SigNoz allows developers to move from symptoms to evidence without stitching together multiple disparate tools.
Developers and engineering teams love SigNoz for its predictable, usage-based pricing model that avoids the common pitfalls of per-host or per-user billing. It provides a unified query experience with PromQL, a query builder, and ClickHouse SQL, making it easy to correlate high-cardinality telemetry data. Additionally, SigNoz is deeply integrated with AI, offering an MCP server and an AI teammate (Noz) that can investigate incidents, tune alerts, and build dashboards directly
