Prometheus vs AppDynamics

A side-by-side comparison of features, pricing, and use cases to help you choose the right tool.

Prometheus and AppDynamics are often evaluated together by teams building out their reliability stack. Prometheus (open-source metrics monitoring and alerting toolkit, founded 2012) is typically a fit for DevOps, SREs, and Platform Engineers, while AppDynamics (application performance monitoring with business transaction tracking, owned by cisco, founded 2008) leans toward Enterprise DevOps, Application Performance Teams, and IT Operations. Both cover 6 of the same core capabilities, so the decision usually comes down to where they diverge.
