TWiki is a free, open-source enterprise wiki and collaboration platform for intranets, extranets, and web applications. Its structured content, forms, variables, and plugins let teams build wiki applications and workflows. Users edit pages in a browser, with automatic links, formatting rules, and full-text search that supports regular expressions. TWiki records revisions to pages and attachments, allowing retrieval of earlier versions and comparison of changes. Administrators can set detailed read and write restrictions for users and groups. Plugins extend the software without changing its core, and developers can create them in Perl using the plugin API. The LdapContrib package can connect LDAP authentication, user mapping, and authorization, including LDAP groups in access lists. TWiki is installed on a web server; its production guide covers Apache on Linux and points to guidance for other environments. Requirements include Perl 5, shell commands, and RCS, with possible additional needs for plugins. Released under the GNU General Public License, it runs across Linux, macOS, Windows, and web environments. Support is not included; documentation, a user forum, an IRC channel, and consultants are listed.
