What is the Visual Traceroute?

This traces the chain of routers your traffic passes through on its way to a destination and how long each hop takes, so you can see where along the path delays or drops happen.

How it works

On the server, it runs the system's own traceroute (or tracert on Windows) as a child process and streams its output back to the browser line by line as hops arrive — falling back to a public MTR API when running on a serverless host that can't spawn native network commands. Each hop line is parsed for its hop number, responding host, and round-trip times and rendered as a live-updating table.

SysAdmin & security use cases

See which hop along the route is adding the most latency.
Distinguish a slow internal network segment from a slow ISP or upstream hop.
Spot a router that stops responding entirely, which often points to a firewall or dead link.
Compare the path taken to the same destination from different networks.
