Comparison of wiki farms

This comparison of wiki farms details notable online services which host wiki-style editable web pages. General characteristics of cost, presence of advertising, licensing, and Alexa rank are compared, as are technical differences in editing, features, wiki engine, multilingual support and syntax support.

General comparison

The following tables compare general information for several of the more than 100 wiki farms that have been created.^[1]

The Alexa traffic rankings are not accurate for those wiki farms that allow some of their hosted wikis to have separate domain names. In those cases there may be some additional Alexa rankings listed below for some of the larger individual wikis in a wiki farm. And the Alexa rankings may be different with respect to time.
