You could also try BuyMeACoffee and LiberaPay, or even Patreon, or all of them.

I suppose this is the same thing, just, using GitHub Sponsors, no? Are there significant differences?

		I have not used GitHub Sponsors so I cannot tell, but GitHub Sponsors may be more accessible to developers. So you should probably use whichever is more accessible to others, less friction = better. That said, having more options is probably better either way, I assume.
