Why is Wikipedia free


The immense success of Wikipedia also made the software known to create the online encyclopedia. With the help of Wiki tools, work teams or entire companies can build up a central knowledge base. Every user has the opportunity to publish their know-how on a specific topic quickly and easily.

The decisive factor for the benefit that a wiki brings is not just the right tool. The users must also be able to present their information in a structured and as objective manner as possible. Other technologies, such as blogs, are better suited for a spontaneous exchange of views.


One of the most popular tools is MediaWiki, as Wikipedia is based on this software. The tool thus offers all the functions that the user is used to from the Internet dictionary. The contributions can be divided into categories and versioned, for example. Templates make it easier for users to insert content. Thanks to user management, the rights for creating and changing posts can be restricted for certain groups. The directory service protocol LDAP can be integrated via a plug-in. Another plug-in enables PDF export.

Above all, MediaWiki offers advantages when it comes to managing large amounts of documents. The solution is open source software. Since the tool is used for Wikipedia, the user can assume that WikiMedia will be continuously developed.


TWiki is also open source software. The tool is widely used and widely used in professional settings. According to the TWiki community, many large companies are working with the solution.

TWiki offers the typical wiki functions such as version control, user management or tagging. Content can be exported as PDF and presentations. Files can also be attached. A WYSIWYG editor is available to the user to edit contributions. The LDAP protocol can be integrated via a plug-in. There are also many other plugins available for TWiki.
