Speedtest comes in multiple flavors and in multiple languages. In spring 2025, you can get Speedtest as:
- a Windows application (Speedtest® for Windows)
- a Macintosh application (Speedtest® for Mac)
- an Android app (Speedtest® for Android)
- an iOS app (Speedtest® for iOS)
- an Apple TV app (Speedtest® for Apple TV)
- a Command Line Interface (CLI) for macOS, Windows, Linux and FreeBSD (Speedtest® CLI)
Besides that you might use the online version speedtest.net or an Ookla clone.
Language support
Speedtest support 17 languages.
However Speedtest Custom supports 19 languages. The two additional languages that Speedtest Custom supports are Danish and Hebrew.
We have checked this in Firefox with the Locale Switcher extension and indeed Danish and Hebrew are supported in Speedtest Custom, not in Speedtest itself.
