V2 COMING SOON!

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

Domain name	Features
⚡ *.is-a.co

Wildcards (like *.foo.is-a.co) are supported too

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?
