Typo (software)

Typo is a free, open source (MIT License) blogging engine written in the Ruby programming language, using the Ruby on Rails web application framework. Typo can use any of the various SQL databases supported by the Ruby on Rails framework. Typo 5.1 was released on July 21st, 2008.

Typo is not to be confused with TYPO3, which is another widespread open source content management system.

History

The name Typo originates from the initial developer of the software, Tobias Lütke, who inadvertently wrote down the incorrect time (a "typo") for an appointment with a client and proceeded to write the first version while sitting in a Starbucks coffee shop during his newly found free time (the blog post).
