What they do

Problem

Teams lack an easy way to observe and debug all inbound and outbound HTTP network activity across running processes without modifying code or requiring privileged access.

Solution

Subtrace provides a zero-code, real-time network tracing tool that uses eBPF to capture and display HTTP requests for processes without root privileges or code changes.

Who it's for

Developers and DevOps/SRE teams who need to debug and monitor network behavior in their infrastructure.
