Domain Extensions / .fyi

.fyi domains

The .fyi domain turns the familiar shorthand "for your information" into a web address built for sharing knowledge. It suits news and information sites, company and product update pages, FAQs and help centers, directories, and personal pages that point people to useful facts. The three letters are instantly understood and effortless to type, which makes a .fyi address memorable and well suited to content whose whole purpose is to inform. Registration is open worldwide with no restrictions, and pricing is typically affordable. For a project, a brand, or an individual that wants a short, no-nonsense address signaling "here is what you need to know," .fyi communicates that promise the moment someone reads the name.
