There's a bunch of them (Vimeo, Dailymotion, Odysee, etc) but they have pretty much the same problems Youtube have nowadays.
The only real alternative I'd highly recomend is Peertube. It works totally fine to upload videos, follow channels, comment on stuff and even livestreams. But unlike any of the others it's closer to how the old good e-mail works, in the sense that there isn't a corporation running the entire platform but more like hundreds of servers or providers and all connected to all others and able to communicate regardless of whenever we registered our account.
The userbase and the general vibe may remind a lot to that mid-late 2000s spirit: lots of people making and sharing stuff and having fun without the usual narcisistic and pointless ambitions we are used to see from the so-called "youtubers" and "social media" in general. It just needs time to get your stuff to be known and due to the lack of algorhythms it might be not that easy for your work to reach an audience, but it's worth it.
