I use iperf3 with Speedtest’s servers, personally. But for a browser, yes JavaScript is needed… But needing JavaScript files from like 20 different domains is typically a red flag for me on any site.
It doesn’t need javascript from “20 different domains”, only a file called empty.php is fetched from those servers to measure the ping. The javascript is hosted on librespeed.org, which is under my control.
I mean, how else are you going to do a speed test?
Speedtest cli
