network diagnostics, reimagined

A console for the people who keep
the network up.

Trace Warrior is equipment, not entertainment. Dense data, fast feedback, a quiet UI that gets out of the way. DNS, TLS, ports, headers, geo, hashing, encoding. The long tail of network forensics.

Plus monitors that watch your certificates, DNS, ports, uptime, ping and domains, and alert you by email or webhook. 3 monitors free, no card.
