Fiddler can be used to debug traffic from virtually any application that supports a proxy like web browsers, mobile apps, IoT devices, and more.

Prometheus: Prometheus is an open-source systems monitoring and alerting toolkit. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts if certain conditions are met.

Both tools serve their respective audiences. Compare the features, pricing, and user ratings above to determine which best fits your needs.
