Is SigNoz an uptime monitoring tool?

No. SigNoz is an Application Performance Monitoring (APM) platform for distributed tracing, logs, and metrics. It monitors app internals, not external availability. PingZen is purpose-built for uptime monitoring with 22 protocols.

Can SigNoz replace PingZen?

No. SigNoz requires instrumenting your code with OpenTelemetry to collect traces and metrics. PingZen monitors your endpoints externally with zero code changes. They serve fundamentally different purposes.

SigNoz Community Edition is free and self-hosted (you manage infrastructure). Cloud plans start at $199/month with usage-based pricing. PingZen is free forever as managed SaaS — no infrastructure needed.

Should I use SigNoz and PingZen together?

Yes, they are perfectly complementary. PingZen tells you "is it up?" from the outside. SigNoz tells you "why is it slow?" from the inside. Together they provide complete observability.

PingZen vs SigNoz: Uptime Monitoring vs Open-Source APM

SigNoz is an open-source observability platform (Y Combinator W21) offering APM, distributed tracing, log management, and metrics — a unified alternative to Datadog and New Relic. Built on OpenTelemetry and ClickHouse, it is not a traditional uptime monitoring tool but rather an application performance monitoring (APM) platform.

Migration Tip

SigNoz and PingZen are completely different tools. SigNoz monitors what happens INSIDE your application (traces, logs, metrics). PingZen monitors FROM OUTSIDE whether your application is available. Use both: PingZen for uptime, SigNoz for performance insights.
