# Subtrace

> Subtrace is a zero-code network tracer for backend servers. Started with a single command, it captures every incoming and outgoing HTTP request in real time - payload, headers, latency, and status - and shows them in a Chrome DevTools-style interface. It uses eBPF to do this without code changes or root privileges, so engineers can find, inspect, and replay production requests instead of grepping through scattered logs. The tool is open source (BSD-3-Clause) and came out of Y Combinator's Winter 2025 batch.

## Products & services

- **Subtrace** — Zero-code network tracer that captures every incoming and outgoing HTTP request in real time and presents them in a Chrome DevTools-style interface. Supports search and filter, full request inspection (payload, headers, latency, status), record-and-replay, and team sharing. Runs on Docker, Docker Compose, and Kubernetes.
- **Subtrace open-source tracer** — The core tracer released under a BSD-3-Clause license on GitHub, built on eBPF to capture traffic without root privileges or code changes. Started via a single 'subtrace run -- [command]' invocation.
