I have been looking for a linktree alternative, and u.page seems like a great alternative. It didn't seem too intuitive, though and it took me a while to figure out how to get my "bio" page up.

u.page advertises that you can use your own domain. This process, however, seem lacking - or just not very well documented. I added an A record for my domain (a .dev tld) that requires SSL. Support's response was that I had to purchase a certificate - but how can I publish my ssl certificate?

If You are fine using one of their portfolio of domains, this is a great way to publish your bio - but if You like me, like to use your own domain, it appears to not be the way to go.
