Created from a lot of back and forth with Claude to help my ISP debug a packet reordering issue. I got tired of running file transfers and pasting the outout of ss -tin into Claude.

Requires javascript to see the load banner. Work in progress. I wanted something that shows more information than speed.cloudflare.com and fast.com and was highly hackable via curl. It will show some curl examples after the first run. No idea how well it will handle HN's load.

If you have dual-stack IPv4 and IPv6, click advanced and there should be an option to test both. It will take longer and use more bandwidth.

Click advanced to control how much bandwidth this uses. It can use a lot. The longer the run the more accurate the TCP statistics.
