To claim a .dev, all you have to do is sign up with your registrar of your choice (Google is of course an option). As a bonus, Google offers a free .dev domain to anyone who applied for a Google I / O event ticket in May. By default, the domains will be safe as they all require HTTPS, and Google has already moved many of its own sites (including web.dev, opensource.dev and flutter.dev) to the domain.
The Internet has come a long way from the day for .com, .org and .net. Now you can get domains ending in everything from .cool to .ninja. And there are real value in unique domain changes. Initially, they can give visitors a better idea of what your site is about, and as meaningful .com URLs are gobbled up, new top-level domain sites open up. Have you ever tried to claim yourname.com to find it listed for sale at a price of $ 2000? Maybe yourname.dev would be a better (and more affordable) fit.
