SigNoz is an OpenTelemetry-native observability platform built by SigNoz Inc. that puts application performance monitoring, distributed tracing, log management, metrics, dashboards, and alerts into one tool. It is available as self-hosted software for Docker, Linux, and Kubernetes, and as the usage-based SigNoz Cloud.[1][2]
Quick verdict
Open-source observability with logs, metrics, and traces in one tool SigNoz is an OpenTelemetry-native observability platform that unifies APM, tracing, logs, metrics, dashboards, and alerts, self-hosted or on usage-based cloud. It documents migration from Datadog most directly and suits teams standardizing on OpenTelemetry.[1][2][3]
What SigNoz covers
APM views report P99 latency, Apdex, and database and external calls per service.[1]
Logs, metrics, and traces live in one OpenTelemetry-native application with trace correlation built into log search.[1][2]
Tracing supports loading and analyzing large traces, dashboards are built with a visual query builder, and alerts cover threshold, anomaly, and Apdex conditions on any telemetry signal.[1][2]
Collection uses OpenTelemetry SDKs and the OpenTelemetry Collector, storage builds on ClickHouse, and the docs expose an API reference for programmatic access.[1][2]
Who it fits
Teams that standardize on OpenTelemetry and want logs, metrics, and traces correlated in one place fit well, since the whole platform is built around that workflow.[1][2]
Teams watching Datadog-style per-host and per-seat bills fit the usage-based cloud packaging, which charges only for ingested telemetry with a $49 monthly minimum.[1][2]
Larger organizations with residency or procurement needs fit the Enterprise tier, which offers US, EU, and India data centers, dedicated or BYOC cloud, and SLA-backed support.[1]
Limits to weigh
Self-hosting runs on your infrastructure with ClickHouse storage behind it, so it asks for more operational attention than signing up for the managed cloud.[1][2]
The repository splits licensing: the core outside ee/ and cmd/enterprise/ is MIT-licensed, while enterprise directories use a separate license, so feature availability depends on which edition you run.[1]
SSO via SAML is documented, but the plan restrictions were not verified in this research, so confirm SSO availability on your tier before relying on it.[1]
Replacing your current stack
The official Datadog migration guide maps metrics, traces, logs, dashboards, and alerts to SigNoz equivalents, including replacing dd-trace libraries and the Datadog Agent with OpenTelemetry tooling.[1]
Docs also list migration guides from Grafana and New Relic alongside Datadog, which keeps the documented switching story wider than one incumbent.[1]
SigNoz publishes a cost analysis claiming up to 9x more value for money than Datadog; treat it as the vendor's own measurement, not an independent benchmark.[1]
Datadog is the incumbent SigNoz documents against most directly, with migration guides, a comparison page, and a cost analysis aimed at Datadog bills.[1][2]
Questions worth asking
Is SigNoz fully open source?
How does SigNoz Cloud pricing work?
SigNoz Cloud Teams starts at $49 per month including $49 of usage, then bills logs and traces at $0.30 per GB ingested and metrics at $0.10 per million samples. There are no per-seat or per-host fees, and an Enterprise tier with custom pricing covers dedicated cloud, BYOC, or supported self-hosting.[1]
Can I run SigNoz on my own infrastructure?
Does SigNoz document replacing Datadog or Grafana?
