So localhost works great for most of your testing. But what happens when you need to test subdomains like test.localhost?

Did you know that http://lvh.me resolves to 127.0.0.1 (AKA localhost)? This is particularly useful when developing locally websites that require subdomains. http://sub.localhost isn’t an option, but http://sub.lvh.me is. Another option (waaaaay more memorable) is http://localtest.me/.

I’m not sure who created lvh.me, my 20 seconds google didn’t turn out anything, but localtest.me was created by Scott Forsyth.
