What Is AppScope


AppScope is an open source, runtime-agnostic instrumentation utility for any Linux command or application. It helps users explore, understand, and gain visibility with no code modification.

AppScope provides the fine-grained observability of a proxy/service mesh, without the latency of a sidecar. It emits APM-like metric and event data, in open formats, to existing log and metric tools.

It’s like strace meets tcpdump – but with consumable output for events like file access, DNS, and network activity, and StatsD-style metrics for applications. AppScope can also look inside encrypted payloads, offering WAF-like visibility without proxying traffic.
