Are you making a website? Do you need to run a webserver on your own computer? Do you use cookies, localstorage, and HTTPS?
Turns out `localhost` and `127.0.0.1` don't work with many features of the web. You need an actual domain name. That's where we come in!
`l.calh.st` is an easy to remember alternative, and it's a real-life domain name with IPv4 and IPv6 support. It will ALWAYS resolve to your local computer. No data is ever sent to our server... unless you accidentally use `www.l.calh.st` - so don't do that!
Test it for yourself!
http://l.calh.st/
