PMwiki is a wiki-based system for collaborative creation and maintenance of Web sites. PmWiki pages look and act like normal Web pages, except they have an "Edit" link that makes it easy to modify existing pages and add new pages into the Web site, using basic editing rules. You do not need to know or use any HTML or CSS. Page editing can be left open to the public or restricted to small groups of authors. Running PMwiki as a JumpBox allows you to be up and running with this software in minutes on any operating system. It carries other benefits such as portability across computing environments, a Web-based admin console to simplify administration, and a built-in automated backup system to protect your work.

Oddmuse is a Wiki engine, a CGI script that creates an entire Website with editable pages. By default, anybody can edit the pages. The entire site can be made read-only, and single pages can also be made read-only. In that case, only people having the admin or the editor password can edit pages. This way, the Wiki can be used as a cheap, simple, and easy-to-understand content management system (CMS). The site can also be switched to Weblog style, such that anybody can post comments, but only the editor can add new pages.

Piggydb is a Web application provided as a self-contained package that contains a Web server and database engine.
