• EditThis.info: — this MediaWiki host is 100% free. However, it appears to have been abandoned by their system administrators (the feature requests page has little to no responses, and the village pump has been blanked and protected). Also, this host is running an ancient version of MediaWiki, and thus is significantly lacking the latest features.
• Miraheze: — users should be aware that despite what is advertised, Miraheze developers do not allow wiki founders to fully manage the configuration settings. Some of the extensions are similar to that of the Wikimedia Foundation, but many of them are strictly off-limits. Miraheze staff have also been known to interfere with local community operations.
• Referata: — this host specialises in Semantic wikis. Users should be aware that the site appears to have become a dormant wiki hosting provider, as the feature requests page has been abandoned for some time, and the recent changes is usually filed with account creations.
• ShoutWiki: — social tools are one of ShoutWiki's fields of expertise. A charge of $5.50 is required to remove page-cluttering adverts, which the site unfortunately relies on for funding. Some highly technical features are available to staff only. ShoutWiki staff consists of experienced MediaWiki developers and editors.
• Wiki.Wiki: — as of December 2016, the ability to create wikis has been removed. Attempting to request a wiki returns a message saying "we are evaluating the wiki.wiki program right now and are not creating new wikis for a while". This message has been present for over three months, and filing a request returns absolutely nothing.
• Wikia: — this host is prolifically advert-spammed, with no paid removal option available, and the staff is not very open to founder configuration control. There are many features that are available to staff-only.
