"Why?" Sometimes, the most unentertaining answer is the correct one--which is just junior developers creating toy apps to boost their resumes in a tough hiring market. It's the same reason the npm ecosystem is flooded with so many garbage packages.
Shouldn't of put the "made by" on it, I took it down since. Was just trying to appease another commenter who asked for attribution. Not sure what makes some one a junior developer.
why are there multiple versions of anything? people can choose the one they like, and all are different somehow.
I personally prefer fast.com because it's quick to type in and typically I'm only looking for download speed, but the real-time graph on this one here is pretty cool
There are ISPs out there that give priority and optimized the speed to Ookla Speedtest whenever the browsers connected to it. This causes skewed results believing that we are getting the speed we paid for when it is not in reality. In a way, it would do "unlimited speed" the maximum it can go just for this test.
Netflix Fast are connected to multiple Netflix CDNs throughout regions. They will get a realistic speed meter and difficult for ISPs to fake it.
Fast give me 300Mbps. I haven't tried out Cloudflare speedtest until now, it give me 335Mbps. My internet package is 300Mbps, so it is consistent with the speed that I get from my ISP.
Fast can also measure some more connection metadata if you click "show more info". A bit annoying it requires the extra step to start measuring ping and upload speed, but it is there.
Fast shows you how fast your ISP WAN is, as the speed test goes to your local (ISP) Netflix cache. I like speed tests that go outside the ISP to get an idea of bandwidth to the internet
The site claims superior accuracy (which I can't confirm but probably someone here can evaluate one way or the other). The site offers a number of test options and other amenities.
I'll have to try these other sites to see how they compare.
