TWiki is a flexible, powerful, and easy to use enterprise wiki, enterprise collaboration platform and knowledge management system. It is a Structured Wiki, typically used to run a project development space, a document management system, a knowledge base, or any other groupware tool, on an intranet or on the internet. TWiki looks and feels like a normal Intranet or Internet web site. However it also has a Edit link at the bottom of every topic (web page), everybody can change a topic or add content by just using a browser.

Web content can be created collaboratively by using just a browser. Users without programming skills can create web applications. Developers can extend the functionality of TWiki with Plugins. TWiki fosters information flow within an organization; lets distributed teams work together seamlessly and productively; and eliminates the one-webmaster syndrome of outdated intranet content.

TWiki is GPLed software. The Perl CGI source code, templates and documentation is available for free.
