That is exactly how fast.com works for internet speed tests. You open it, it runs, you see a number. Done. - Source: dev.to / 3 months ago
Pro tip: Run a speed test immediately before the event. Don't trust your "up to 100 Mbps" ISP claim. Use fast.com or speedtest.net to get real numbers. - Source: dev.to / 7 months ago
Speedtest has always seemed incredibly sketchy to me, I don’t know if others share this sentiment. https://fast.com completed the test faster than speedtest loads the site. - Source: Hacker News / 7 months ago
