Buy your .fyi domain today

.fyi domains are used by sites whose main job is to tell you something. Documentation, release notes, status pages, event details, internal wikis and single-purpose explainers all sit naturally on the extension.

The pattern holds because the letters set an expectation before the page loads. A visitor arriving at an address ending in .fyi expects to read, not to be sold to, which is exactly right for a changelog and exactly wrong for a checkout.

Independent writers and small teams use it the same way. One of the longest-running examples is txt.fyi, a stripped-back publishing tool with no accounts and no design choices, which is about as pure a statement of the extension as you can get.

No, .fyi is open to anyone, and the registry asks for no proof of anything. There is no company number to supply, no country you have to live in and no industry test to pass.

That is a policy position rather than an oversight. The registry publishes portfolio-wide rules on acceptable use and reserved names, and no eligibility document for .fyi exists at all, because there is nothing to restrict.

In practice you search for the name, pay and it is yours, first come first served. The only gate is availability, so have a second and third choice ready before you start.

.fyi stands for “for your information”, the same abbreviation people have typed at the top of forwarded emails for decades. That is its whole advantage and also its main risk.

Among people who read and write English online the abbreviation needs no explanation. Outside that group it can land as a jumble of three letters, and this is the objection domain buyers raised about the extension from its earliest days.

The practical test is simple: say the name out loud down a phone line and see if it survives. “Guide dot F Y I” works because the letters are spelled, not pronounced. If your audience is broad and offline, put the full address on print rather than trusting recall.

.fyi rests on an abbreviation people genuinely wonder about, and "is FYI still used" is a question searchers type directly. The short answer is yes, in writing, and nothing newer has replaced it.

It survives because it does a job no single word does: flagging that what follows is information rather than a request. That keeps it in email subject lines and internal notes, which is exactly the register the extension borrows.

What it is not is neutral. FYI sounds like workplace shorthand, so it reads as current and practical rather than warm or crafted. For a documentation site that is right. For a personal brand it may not be.

Yes, a .fyi domain works well as a second address pointing at part of your main site. Plenty of teams keep the .com for the product and hand the reference material its own short name.

Technically there is nothing special to do. You point the .fyi name at the same site and choose a page for it to land on, or you build the docs separately and link both ways. Wix lets you connect more than one domain to a single site.

One thing to settle first: pick which address you want indexed. Search engines should see one canonical version of each page, so decide early which name is the real one and make the other a redirect rather than a duplicate.

For a short, modern reference site .fyi usually reads better than .info. The two aim at the same job, and the difference is tone rather than function.

.info is older and much larger, which cuts both ways: it is familiar, and the good names went long ago. .fyi is newer and shorter by two characters, so more plain words are still free, and it sounds like something a person would write rather than a category label.

Try both on your shortlist before deciding. If your name is available on .info and reads naturally there, the extra familiarity is worth something, particularly for an audience that has been online a long time.

A .fyi address sends the wrong signal when the page is asking for something rather than telling you something. Searchers ask when not to use FYI, and the same instinct applies to the domain.

In writing, FYI can land as curt when it precedes a request, and the extension inherits some of that. An address ending in .fyi in front of a sales page, a donation appeal or a booking form creates a small mismatch: the ending promises information and the page wants action.

Use it where informing is the whole purpose and keep transactional pages on your main name. If you will only have one address and it takes payments or bookings, choose a different ending.

Yes, .fyi is a good domain for a side project, especially if the project shares information, tips, updates or resources.

The .fyi ending gives the domain an informal, information-first feel, which can work well for a personal project, newsletter or niche resource.

Before registering, check the renewal price and make sure the name still makes sense without explaining what "fyi" means.
