While they have some (technical) downsides I figured they'd be interesting to experiment with so I was curious if any good ones were still available. Manually checking them one-by-one was kinda cumbersome, so I wrote a simple script to check availability for each possible single-emoji .to domain.
Turns out many were still available (about 70% at the time). I registered a few and decided to publicise the list. That was my weekend project ~2 weeks ago. Today I finally launched it.
I wrote more about the timeline and how I built it here: https://medium.com/@marckohlbrugge/get-your-own-emoji-domain...
Disclosure: I worked out an affiliate deal with my registrar so I get a 10% commission for each registration. Of course you're free to use your own registrar of choice.
I bought 🇸🇾 and 🇨🇿. Romania was taken already, sadly.
IMO, It's a safe bet against emoji domains taking off.
I personally wouldn't use them for a website where users would have to repeatedly enter the URL. They work better for advertising campaign as a redirecting link (e.g. on a billboard), or in situation where the URLs tend to be clicked instead of written.
