.fun domains

The .fun domain is exactly what it says: a bright, upbeat extension for anything built around entertainment and enjoyment. Games, events, festivals, toys, amusement venues, kids' brands, and playful marketing campaigns all use .fun to set an immediate, lighthearted tone. The word is universally understood, easy to spell, and memorable, which makes a .fun address well suited to a name that should feel approachable rather than corporate. Registration is open worldwide with no restrictions, and pricing is typically low, so it is a popular choice for campaigns, side projects, and community sites as well as established brands. For any venture whose whole point is to entertain and delight, .fun communicates that promise before a visitor even reaches the site.
