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.

Company
Subtrace
Zero code network tracer
We built a network tracer that requires zero code changes and no root privileges. It shows every HTTP request your process makes or receives in real time, like an inspect element button for your infrastructure. We use BPF under the hood to make this possible without intrusive setup.
We live and base the company in San Francisco, CA, USA. We plan to continue here after YC.
San Francisco is where both of us live and work now. Being in the Bay Area puts us close to engineers and companies who face these networking debugging challenges, and is convenient for YC and the startup ecosystem.
