Speedtest Custom™ variants

This is a large but incomplete list of Speedtest Custom™ variants. That is, all speed tests shown are based on Ookla's Speedtest.

An exhaustive list

We know that this is an exhaustive and incomplete list because we have discovered that several Speedtest Custom™ variants asks for a Test Password.

A simple form with the text: "Enter Test Password", an entry field and a submit button

Besides that some Speedtest Custom™ variants only work when embedded, if you run them separately you will get a 404 error.

The speedtestcustom error page shows the text: "404 Oops! There seems to be a problem with this page. Either the URL was misspelled, this page never existed, or it has been removed. In the meantime, you can explore Speedtest Custom."

The main reason why this list is not complete is of course that we can only find out indirectly (by searching) which Speedtest Custom™ variants there are.

How many Ookla clones are there?

Probably only Ookla knows how many Ookla clones there are. Based on what we know, we can make an estimate.

BuiltWith claims that there are almost 3600 websites that use Speedtest Custom™. However, we feel that this list contains too many websites and that the actual number of websites using a Speedtest Custom™ variant is much lower.

When you search in Bing for site:speedtestcustom.com you get roughly 15,000 results.

If you search in Bing for site:speedtestcustom.com Bing will show: "About 14,900 results"

On the one hand, we think that Bing shows quite a few speed tests twice, which would mean that the number of unique Speedtest Custom™ variants is a lot lower.

On the other hand, we are surprised by who offers a Speedtest Custom™ variant. Take Zeeuw & Zeeuw for example. This is a mobility provider that is among the top 10 Dutch car dealers. What do they need zez.speedtestcustom.com for?

The number of companies that purchase a variant is therefore probably higher than we think.

Ultimately, our assumption is that there are 10,000 to 20,000 Speedtest Custom™ variants.

Free Speedtest Custom™ variants

Probably the most important reason for the large number of Speedtest Custom™ variants is that it was possible to create your own Speedtest Custom™ variant for free until October 2022.

Below you can see a screenshot of the Wayback machine from September 2022.

All Speedtest Custom™ variants have the basic URL [customer].speedtestcustom.com and all Speedtest Custom™ variants are in principle equally good (although there are clones like secv.speedtestcustom.com that start automatically). We have looked (based on a limited list) which Speedtest Custom™ variant is the best. We concluded that speedtpe.speedtestcustom.com is the best Ookla clone.
