In their words

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.

Is this you?

If you're behind Subtrace: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. FoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.

Sourced from the company's Y Combinator directory entry.
