@davidak cool, thank gou for the link!
@codeberg you are on Hacker News. there you have some feedback to the service.
No, we are not a registrar ;)
That said, you can set up a redirect, alias or cname at your registrar, also there are dedicated redirect service providers. Long story short: custom domains are well possible, setup is however on the other side.
Hope that helps!
