.boo domains

The .boo domain is a short, playful extension operated by Google Registry, used for personal sites, creative projects, seasonal campaigns, and brands that want a friendly, memorable web address. The word is expressive and warm, working equally well for a term of affection or a lighthearted Halloween theme, which gives it broad creative range. Because it is only three letters, short and catchy names are still available where a common gTLD would be taken. As with all Google-operated TLDs, .boo is on the HSTS preload list, meaning browsers require HTTPS for every .boo site, so security is built in from day one. Registration is open to anyone worldwide with no restrictions and follows standard yearly terms. For a personal brand, a small project, or a playful campaign, .boo offers character, brevity, and secure-by-default connections in a single tidy extension.
