Their GitHub page is some confusing bullshit where they seem to have taken the repo of a completely unrelated Angular animation library that has been inactive for 6 years and converted it to be Tipe, presumably to make it seem as if Tipe has earned 2.1k stars when it was actually the Angular project that earned those stars.
They claim to be open-source but I see zero source code. Maybe the source is in one of the two different CLIs that seem to exist? But the one that actually seems documented and usable hasn't had a commit in 10 months.
