.wiki is an open extension for collaborative knowledge: fan wikis, documentation, team handbooks and reference sites that many people help to write. Anyone can register one, and it has been in the internet's root since February 2014.
PD Hosting is a UK company and Nominet accredited registrar. A .wiki ordered from us is registered at once and managed from your client area, with renewal reminders before it's due.
Per year. Compare every extension on our domain pricing page.

Who a .wiki domain suits
Fan communities building a guide to a game, a book series or a football club's history; open-source projects that want documentation anyone can improve; local history societies collecting memories and photographs of a town.
Companies use .wiki for product documentation and support knowledge bases, and for internal handbooks behind a login. Teachers and researchers use it for shared course notes and glossaries.
- A fan wiki for a game, show or sport
- Open-source project documentation
- A product knowledge base
- Local or family history collections
- An internal staff handbook
Benefits of a .wiki domain
Invites contribution
The word "wiki" signals a shared, editable reference, which encourages readers to join in.
Suits documentation
Product and project names are often free in .wiki even when the .com is taken.
Works with any wiki software
Whatever wiki software you host can run on a .wiki address with no special setup.
From a Hawaiian word to a domain extension
"Wiki" is a Hawaiian word meaning quick. Ward Cunningham borrowed it in 1995 for WikiWikiWeb, the first website any reader could edit, after the Wiki Wiki shuttle bus at Honolulu airport. The idea spread, and "wiki" came to mean any site built and maintained by its readers.
A .wiki address tells visitors to expect that kind of site. It isn't tied to any particular encyclopedia or software, and the registry doesn't require a .wiki to be publicly editable. But the name sets an expectation, so it suits sites where people really do contribute, or at least where content is organised like a reference: one page per topic, linked together and kept up to date.
Open wikis also attract spam edits. If you let the public contribute, choose wiki software with account sign-up, edit review or rate limits, and keep it updated. A neglected open wiki filled with spam can drag down how search engines see the whole domain.
.wiki pros and cons
Works well if
- You're building a reference that many people edit
- You run a fan community or an open-source project
- You want product documentation on a self-explanatory address
Look elsewhere if
- One person writes the whole site: .blog or .info sets a more accurate expectation
- You need a customer support centre: .help says that more directly
- You want the most familiar address for a business: .com or .co.uk

| .org | Non-profit projects and communities | Widely recognised, with a broader purpose. |

.wiki questions
Is .wiki connected to Wikipedia?
No. The .wiki extension has its own registry and is open to anyone. Any project can use it, whatever software it runs on.
Who is eligible to register a .wiki?
Any person or organisation, anywhere. There are no eligibility rules.
Does a .wiki site have to be publicly editable?
No. The registry sets no rules about how a .wiki site works. Many are internal handbooks or documentation edited by a small team.
Is a .wiki domain good for search visibility?
Google treats the extension like any other generic domain. Wikis can rank well because they're organised into focused, linked pages, but spam edits on an open wiki can do damage, so moderate contributions.
What does a .wiki cost from year two?
Renewal costs £45.95 a year. The first-year price is lower, so expect a higher bill from the second year.
How do I verify my .wiki after registering?
Follow the link in the verification email we send. ICANN's rules require us to confirm the owner's email address; if it isn't confirmed within 15 days, the domain is suspended until it is.
