Subtrace gives backend teams full visibility into every API request — payload, headers, status code, latency, logs — in a Chrome DevTools-like interface. No instrumentation. No root. Just subtrace and see everything.
The interface developers actually want. Not a dashboard full of noise.
Most tools require you to instrument your code, install agents, or beg your DevOps team for access. Subtrace just needs a terminal.
Payload, headers, status codes, latency, logs — all stored and searchable. Not just errors. Not just sampled traces. Everything.
Attach to any process without root privileges or code modifications. One command: subtrace run --name <process>. You're live.
Familiar. Fast. Filter by path, method, status, header value, or payload content. Find the request that broke everything in seconds.
Share request traces with teammates. Tag and annotate incidents. Query together — incident response becomes a shared session, not a solo scavenger hunt.
Take any past request and replay it against your live service. Test fixes without faking the payload by hand. Reproduce the bug, verify the fix.
Run Subtrace entirely locally with no data leaving your infrastructure. For cloud sync, end-to-end encryption is available. Designed for regulated environments.
No agents. No configuration files. No DevOps ticket required.
"Subtrace is what you get when someone builds Wireshark for modern backend stacks. The eBPF approach is genuinely clever — it just works without any setup."
"We used to spend hours on production incidents. Now we open Subtrace and the request is right there — payload, headers, timing, everything. It's DevTools for the whole backend."
"The TLS decryption without root is a brilliant hack. This is exactly what container debugging needed — something that understands pods and services natively."
Stop reconstructing incidents from scattered logs. Subtrace shows you exactly what happened, what was sent, and what came back — for every single request, in real time.
Free to start. No credit card required. Runs locally or in the cloud.
