MantisBT – Open source issue tracker

MantisBT is a popular open source web-based bug tracking system. Built on PHP and supports Linux, Windows and Mac OS X on the server side. Compatible with Chrome, Firefox, Safari, Opera and IE 7+. Released under the terms of the GNU General Public License (GPL).

Kenzaburo Ito started development of the Mantis Bug Tracking project in 2000. In 2002 Victor Boctor became the maintainer of the project. Version 1.0.0 was released in February 2006. Version 1.1.0 was released in December 2007. In November 2008, after a long discussion,[3] the project switched from using the Subversion revision control tool to Git, a distributed revision control tool. In February 2010, version 1.2.0 was released. In July 2012, the MantisBT organization on GitHub became the official repository for the Project’s source code.

An event-driven plug-in system was introduced with the release of version 1.2.0.[7] This plug-in system allows extension of MantisBT through both officially maintained and third party plug-ins. As of November 2013, there are over 50 plug-ins available on the MantisBT-plugins organization on GitHub.

Prior to version 1.2.0, a third party plug-in system created by Vincent Debout was available to users along with a variety of different plug-ins.[8] This system was not officially supported by the MantisBT project and is incompatible with MantisBT 1.2.0 and later.

MantisBT supports the sending of e-mail notifications upon changes being made to issues in the system. Users have the ability to specify the type of e-mails they receive and set filters to define the minimum severity of issues to receive notifications about. Users also have the ability to explicitly subscribe to issues that affect them.

RSS feeds are available for users who wish to keep track of issues that have been resolved. Additionally, MantisBT has integration with Twitter via a plugin, to allow a notification to be tweeted when an issue is resolved.

Via MantisBT’s event-driven plug-in system, it is possible to extend the built in notification support to run advanced scripts that perform additional notification actions (such as sending SMS messages or updating statuses in external project management systems).
