.boo costs $14.98 to register with us and $14.98 to renew, at our registrar's own rate with nothing added. .boo is a domain ending that reads as technical. Among people who build software it needs no explanation at all; outside that audience it is a word someone has to be told once. Whether that trade is worth it depends entirely on who you are talking to.
The ending is the part after the dot: the .boo in example.boo. Technical endings became normal because the audience that adopted them first - developers, infrastructure teams, tool-makers - reads addresses closely and treats an unusual ending as a signal rather than a mistake.
The signal is real and it is narrow. Inside the audience, a technical ending buys you credibility and a short, available name. Outside it, you will spell the address on the phone. Neither of those facts is a dealbreaker; both should be decided on purpose rather than discovered later.
Every figure here is read from our registrar, not typed into this page, and is the total for one registration term rather than a per-year rate. A name can still carry premium pricing set by its registry - the amount shown at checkout is the one that applies.
Our registrar has not published a registrant rule for .boo, so we will not claim there is none - "not published" and "no requirements" are different statements and only one of them is ours to make. What we collect and submit is the standard contact set, and our registrar lists .boo as one it will register for us today, so checkout is open. If a registry does turn out to want more, a registration can be refused - worth knowing before you build a brand on the name.
This is a read on one group of endings - software and the internet - rather than on .boo alone. Endings that read as technical - clear to the people who build, opaque to everyone else. The price, the registry term and the registrant requirements on this page are .boo’s own, read live from our registrar.
A product whose users are technical. Developer tools, APIs, infrastructure and anything sold to engineers: the audience reads the ending correctly on sight.
Documentation, status pages, and internal tools. A second address for the technical surfaces of a business is one of the cleanest uses of an ending like this.
Projects and side-projects that want a short name. Technical endings are where an exact, unpadded word is still findable, which matters more than the ending itself.
Anything that will mostly be typed, not spoken. If your address travels through links, repos and READMEs rather than radio ads, the spelling cost mostly disappears.
If your customers are not technical, this is the wrong shelf. A local business, a clinic, a shop or anything sold to the general public pays a real tax on an ending its audience has never seen: people mistype it, some assume it is a typo, and a few will not trust it. The ending is not the place to be clever when the audience is not in on it.
Also weigh what happens if you succeed. A product that starts technical and grows into a mainstream audience ends up explaining its address for years, and the fix - buying the obvious ending later, once you are known - is the expensive version of the decision you are making today.

Some names carry premium pricing set by the registry, well above the standard rate for that extension. Just Domain doesn't register premium names - search will tell you when a name is one.
