Zero code network tracer

What it does

Subtrace is a zero-code network tracer. It's like having an inspect element button for your whole infra: when you start a process with Subtrace, you'll see every HTTP request coming in and going out in realtime. Under the hood, it uses BPF to make this possible without any root privileges or code changes. We have ~2.5k stars on Github.
