I think Monkeytype is an alternative since it also has quotes / phrases, as well as simple words (such as 10fastfingers).
I don't know KeyBr, will check it out.
typingstudy.com is a good resource for especially learning / training touch typing.
Additionally I like to have some offline applications available:
https://github.com/… (equivalent to 10fastfingers).
https://github.com/… (equivalent to typeracer / keyhero - quotes are from typeracer).
