Mastodon on your own domain without hosting a server - Maarten Balliauw {blog}
However, there is one thing I would like my own server for: discoverability. Much like with e-mail, I want folks to have an easy address to find me, and one that I can keep giving out to everyone even if later I switch to a different Mastodon server. A bit like e-mail forwarding to your ISP’s e-mail service.
The good news is: you can use your own domain and share it with other folks. It will link to your actual account.
