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.
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?
