Free subdomains for personal sites, open-source projects, and more. Here is a list of supported domain names:

Domain name	Features
⚡ `*.is-an.app`
⚡ `*.1bt.uk`

Wildcards (like *.foo.is-an.app) are supported too, but the reason for their registration should be very clear and described in detail.

Why?

First of all, I want to answer one important question - "Why are you giving out domains for free?". Because sometimes I need domains for my pet projects, and instead of buying new domains every time, I decided to buy one for everyone, and use subdomains. And why not share them with the community?
