For the online encyclopedia colloquially known as "Wiki", see Wikipedia. For other uses, see Wiki (disambiguation). Editing display showing MediaWiki markup language A screenshot of the MediaWiki homepage, a wiki software A wiki (/ˈwɪki/ ⓘ WIK-ee) is a form of hypertext publication on the internet which is collaboratively edited and managed by its audience directly through a web browser. A typical wiki contains multiple pages that can either be edited by the public or any organization.[1] The name derives from the first user-editable website called WikiWikiWeb – wiki being a Hawaiian word meaning 'quick' (pronounced [ˈviti]).[note 1][2][3][4][5] Wikis are powered by wiki software, also known as wiki engines. Being a form of content management system, these differ from other web-based systems such as blog software or static site generators in that the content is created without any defined owner or leader. Wikis have little inherent structure, allowing one to emerge according to the needs of the users.[6] Wiki engines usually allow content to be written using a lightweight markup language and sometimes edited with the help of a rich-text editor.[7] There are dozens of different wiki engines in use, both standalone and part of other software, such as bug tracking systems. Some wiki engines are free and open-source, whereas others are proprietary. Some permit control over different functions (levels of access); for example, editing rights may permit changing, adding, or removing material. Others may permit access without enforcing access control. Further rules may be imposed to organize content. In addition to hosting user-authored content, wikis allow those users to interact, hold discussions, and collaborate.[8] There are hundreds of thousands of wikis in use, both public and private, including wikis functioning as knowledge management resources, note-taking tools, community websites, and intranets. Ward Cunningham, the developer of the first wiki software, WikiWikiWeb, originally described wiki as "the simplest online database that could possibly work".[9] The online encyclopedia project Wikipedia is the most popular wiki-based website, as well being one of the internet's most popular websites, having been ranked consistently as such since at least 2007.[10] Wikipedia is not a single wiki but rather a collection of hundreds of wikis, with each one pertaining to a specific language, making it the largest reference work of all time.[11] The English-language Wikipedia has the largest collection of articles, standing at 7,225,943 as of August 2026.[12] Characteristics Ward Cunningham In their 2001 book The Wiki Way: Quick Collaboration on the Web, Ward Cunningham and co-author Bo Leuf described the essence of the wiki concept:[13][14] "A wiki invites all users—not just experts—to edit any page or to create new pages within the wiki website, using only a standard 'plain-vanilla' Web browser without any extra add-ons." "Wiki promotes meaningful topic associations between different pages by making page link creation intuitively easy and showing whether an intended target page exists or not." "A wiki is not a carefully crafted site created by experts and professional writers and designed for casual visitors. Instead, it seeks to involve the typical visitor/user in an ongoing process of creation and collaboration that constantly changes the website landscape." Editing "Wikitext" redirects here. For the Wikipedia help page, see Help:Wikitext. Source editing Some wikis present users with an edit button or link on the page being viewed. This will open an interface for writing, formatting, and structuring page content. The interface may be a source editor, which is text-based and employs a lightweight markup language (known as wikitext, wiki markup, or wikicode), or a visual editor. For example, in a source editor, starting lines of text with asterisks could create a bulleted list.[citation needed] The syntax and features of wiki markup languages for denoting style and structure can vary greatly among implementations. Some allow the use of Hypertext Markup Language"}]]}'>HTMLTooltip Hypertext Markup Language and Cascading Style Sheets"}]]}'>CSSTooltip Cascading Style Sheets,[15] while others disallow them to foster uniformity in appearance. Example of syntax A short section of the 1865 novel Alice's Adventures in Wonderland rendered in wiki markup: Wiki markup Equivalent in HTML Output shown to readers "Take some more [[tea]]," the March Hare said to Alice, very earnestly. "I've had '''nothing''' yet," Alice replied in an offended tone, "so I can't take more." "You mean you can't take ''less''," said the Hatter. "It's very easy to take ''more'' than nothing." \"Take some more <a href=\"/wiki/Tea\" title=\"Tea\">tea</a>,\" the March Hare said to Alice, very earnestly.\n\n\"I've had nothing yet,\" Alice replied in an offended tone, \"so I can't take more.\"\n\n\"You mean you can't take less,\" said the Hatter. \"It's very easy to take more than nothing.\""}}'>"Take some more <a href="/wiki/Tea" title="Tea">tea</a>," the March Hare said to Alice, very earnestly. "I've had nothing yet," Alice replied in an offended tone, "so I can't take more." "You mean you can't take less," said the Hatter. "It's very easy to take more than nothing." "Take some more tea," the March Hare said to Alice, very earnestly. "I've had nothing yet," Alice replied in an offended tone, "so I can't take more." "You mean you can't take less," said the Hatter. "It's very easy to take more than nothing." Visual editing This section does not cite any sources. Please help improve this section by adding citations to reliable sources. Unsourced material may be challenged and removed. (March 2026) (Learn how and when to remove this message) While wiki engines have traditionally offered source editing to users, in recent years[when?] some implementations have added a rich text editing mode. This is usually implemented, using JavaScript, as an interface which translates formatting instructions chosen from a toolbar into the corresponding wiki markup or HTML. This is generated and submitted to the server transparently, shielding users from the technical detail of markup editing and making it easier for them to change the content of pages. An example of such an interface is the VisualEditor in MediaWiki, the wiki engine used by Wikipedia. WYSIWYG editors may not provide all the features available in wiki markup, and some users prefer not to use them, so a source editor will often be available simultaneously. Version history Some wiki implementations keep a record of changes made to wiki pages, and may store every version of the page permanently. This allows authors to revert a page to an older version to rectify a mistake, or counteract a malicious or inappropriate edit to its content.[16] These stores are typically presented for each page in a list, called a "log" or "edit history", available from the page via a link in the interface. The list displays metadata for each revision to the page, such as the time and date of when it was stored, and the name of the person who created it, alongside a link to view that specific revision. A diff (short for "difference") feature may be available, which highlights the changes between any two revisions. Edit summaries "Edit summary" redirects here. For the Wikipedia help page, see Help:Edit summary. The edit history view in many wiki implementations will include edit summaries written by users when submitting changes to a page. Similar to the function of a log message in a revision control system, an edit summary is a short piece of text which summarizes and perhaps explains the change, for example "Corrected grammar" or "Fixed table formatting to not extend past page width". It is not inserted into the article's main text. Navigation Traditionally, wikis offer free navigation between their pages via hypertext links in page text, rather than requiring users to follow a formal or structured navigation scheme. Users may also create indexes or table of contents pages, hierarchical categorization via a taxonomy, or other forms of ad hoc content organization. Wiki implementa…
