TL;DR

Key takeaways

  • Native OpenTelemetry ingestion plus lightweight language agents for Node.js, PHP, Java, Python, Go, Ruby, and .NET.

  • Complete Digital Experience Monitoring (RUM, Core Web Vitals, JS error tracking, and Session Replay) which SigNoz lacks.

  • Zero ClickHouse or collector cluster maintenance—Atatus runs as fully managed SaaS or turnkey On-Premises.

  • Predictable flat per-host pricing ($49/host/mo APM, $15/host/mo Infra, $0.75/GB Logs) instead of unpredictable span-volume spikes.

How Does Atatus Compare to SigNoz on OpenTelemetry and APM?

SigNoz is an open-source OpenTelemetry backend built on ClickHouse focused on traces, metrics, and logs. However, self-hosting SigNoz in production requires operating and scaling ClickHouse clusters, managing ZooKeeper/ClickHouse Keeper, and tuning high-cardinality storage.

Atatus accepts standard OpenTelemetry traces, metrics, and logs out of the box while also providing turnkey APM dashboards, service maps, database query analytics, Real User Monitoring (RUM), synthetic uptime checks, and SIEM in one unified platform.
