Hosting with custom domains

How many sites can I publish with a custom domain, on the freelancer site plan?

There is no limit.

I was confused about how workspace plans and site plans interrelate also, so I did some research on this and wrote up my findings here;

So if I understand correctly, if I host sites with a custom domain it does not count towards anything like unhosted websites limit? But I need a paid workspace like ‘freelancer’ to have acces to this?

Correct, because it’s hosted, therefore it doesn’t count as unhosted in your workspace.

No. I think I see where you’re confused-
