There are many wiki farms or wiki hosting services where wikis can be created. Many offer free hosting, but often display ads on each page. Others have various levels of service and monthly fees. Many wikis provide a WYSIWYG (what-you-see-is-what-you-get) editor and do not require that you enter any tags or wiki syntax (often called wikitext). Some wikis also offer business solutions for the hosting of corporate sites or private sites with restricted access.

Some examples of wiki hosting services (i.e., wiki farms) are listed below, along with links to more detailed information.
