There's also a "source" distribution that installs by downloading from the main project's GitHub release page. But that's presumably limited to the same platform support.
The yt-dlp project also raised concerns that the manylinux wheel incorrectly advertises older glibc support.
... but I always bristle a bit at the "one-liner to run without installing" description. Sure, the ergonomics are great, but you do still have to download the whole thing, and it does create a temporary installation that is hard-linked from a cache folder that is basically itself an installation.
Sure, but as an end-user you don't have to think about installation at all. That's a huge win - mainly because it eliminates the "Did I install this already? Where did I put it? What's the command for doing that again?" mental overhead.
