How it works graphic

How it works

When you're building an amazing service, your users might want to bring along their own custom hostname.

It makes sense! A unique domain is a great way to build a brand. But, this can be a pain to configure and maintain...

Typically, you'd need to wrangle a proxy, mass generate and renew SSL certificates, and implement some wily load balancing.

With Fly, just POST a hostname to the Fly API, receive a signed one in return, then have your customers prove ownership through a DNS record.

That's it! You keep shipping features, we'll handle the rest.
