.fyi

.fyi is a generic top-level domain built around the familiar abbreviation for “for your information”. Its tone is concise, informal and naturally suited to informational content.

The extension can work for guides, explainers, documentation, reference sites, newsletters, internal resources and brands that publish useful information about a topic. A subject before .fyi can form a compact phrase that reads like a helpful note.

Because FYI is conversational, it may feel less formal than extensions used by institutions or regulated professional services. That can be an advantage for accessible content but may not fit every brand.

A .fyi domain does not indicate that information is official, independently verified or complete. Readers should still evaluate sources, especially for high-stakes topics.

.fyi is an open generic top-level domain, subject to registry and ICANN policies, reserved names, premium classifications and third-party rights.
