Subtrace

Zero code network tracer

What Subtrace 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.

No open roles recorded right now.

That does not mean they are not hiring — plenty of roles never reach a job board. The careers page below is the earliest place a new opening appears.

Check the company’s own careers page — linked at the top — before a job board. A role appears there first, sometimes weeks before it is syndicated anywhere else.
