Lvh.me no longer resolving to localhost?

Just did some testing and it seems like the latest Chrome and Firefox browsers both support *.localhost, so this is a good replacement.

Works also with port numbers, eg http://example.localhost:3000/

I don't know lvh.me, but it sounds similar to nip.io and xip.io.

If you don't want to rely on a free service to point to your localhost, I recommand ngrok.io. I believe they have a free plan. It works with your virtual hosts as well :-)

This seems like a terrible practice, localhost should resolve to localhost a TLD of its own. Having some random entity controlling a domain at the .me TLD, and using that in a processes is just asking for trouble.

Not an answer to your actual question but you might be able to switch to https://readme.localtest.me/ instead.

GoDaddy are now showing the domain name is expired and parked. Having a bad actor take control of this domain would not be a fantastic outcome.
