Open-source OpenTelemetry APM, logs and metrics · by SigNoz, Inc.

Overview

SigNoz is one of the most popular open-source observability platforms, built from the start on OpenTelemetry. APM dashboards show latency percentiles, error rates, Apdex, database and external calls per service; traces open as flame graphs with up to a million spans; logs are searched in a columnar store and linked to traces; and metrics support PromQL and ClickHouse SQL. Exceptions, alerts, infrastructure and Kubernetes views, messaging-queue monitoring and LLM monitoring are included.

You can run the Community Edition yourself at no licence cost, which suits teams with the skills to operate ClickHouse. SigNoz Cloud removes that work: the Teams plan starts at $49 a month, includes that much usage, and then bills per GB of logs and traces and per million metric samples, with no per-user or per-host pricing.

Cloud data centres are in the US, EU and India. Enterprise customers can choose a dedicated environment, have SigNoz manage it in their own cloud, or get a support contract for self-hosting.

Pricing and plans

Free tier · no card

Community Edition is free to self-host with APM, tracing, logs, metrics, exceptions and alerts; you run the ClickHouse-based stack yourself. The cloud has a trial, not a free tier.

At the limit Not stated The vendor does not say what happens at the limit, or we have not found it yet.

Plan Price What you get
Community Edition $0 (self-hosted) Open source, install and manage yourself
Teams (Cloud) From $49/mo $49 of usage included (e.g. 163 GB logs/traces), then traces and logs $0.30/GB, metrics $0.10 per million samples; unlimited users and hosts
Enterprise From $4,000/mo Dedicated cloud, bring-your-own-cloud or supported self-host; BAA, volume discounts, SLA

The Teams plan minimum is shown as $49/month with $199 struck through, meaning the entry price was lowered. Usage above $49 is billed at $0.30/GB for traces and logs and $0.10 per million metric samples; logs default to 15-day retention and longer retention costs more. Ingestion limits can be set to avoid surprise bills. A startup programme exists for companies under 3 years old, under 30 staff and under $6M raised. SSO/SAML is cloud-only.

Strengths and limitations

Strengths

  • Free, open-source self-hosted edition with the full core feature set.
  • No per-user, per-host or custom-metric pricing on the cloud.
  • OpenTelemetry-native, so instrumentation is portable.
  • EU and India data regions besides the US.

Limitations

  • Self-hosting means running and scaling ClickHouse.
  • SSO/SAML and the Noz AI assistant are cloud-only features.
  • No uptime checks or status pages.
  • Enterprise options start at $4,000 a month.
§5

Who it suits

Good for

  • Teams adopting OpenTelemetry
  • Startups replacing Datadog or New Relic to cut cost
  • Companies that must self-host telemetry

Look elsewhere if

  • Someone who only needs error tracking or uptime pings
  • Teams without capacity to run ClickHouse who also cannot use the cloud
§6

    Announced 2025-05-20: the Teams plan base fee dropped from $199 to $49 a month, still including that amount of usage; per-GB and per-sample rates were unchanged. Source ↗
