qTip

Rarely open sourced projects reach cult status in the Web design community. This happened to WordPress, jQuery, MooTools, Joomla, Drupal and so on.

This is because in any facet of development sometimes programmers might need some help with their code and from all the available free solutions at one point on the market, one or two rise above the rest.

This happened to qTip. Thanks to a well though and planned codebase, the plugin has managed to impress many developers and convince them it's better than the alterntives.

Over the years it has been around, qTip has managed to attract quite a following, being used by a plethora of developers and even big-name companies like Mozilla or Skrill.

This plugin is also available as a GEM file for Ruby on Rails projects.
