GanttProject is GPL-licensed (free software) Java based, project management software that runs under the Microsoft Windows, Linux and Mac OS X operating systems. This project was initiated in January 2003, at University of Marne-la-Vallée (France) and managed, at first, by Alexandre Thomas, now replaced by Dmitry Barashev.


Comparing to other full-fledged project management software, one could say that GanttProject is designed considering the KISS principle.

It features most basic project management functions like a Gantt chart for project scheduling of tasks, and doing resource management using resource load charts. It can only handle days not hours. It does not have features like cash flow, message and document control. It has a number of reporting options (MS Project, HTML, PDF, spreadsheets).[1]

The major features include:

  • Create Work Breakdown Structure
  • Task Hierarchy and Dependencies
  • Gantt Chart
  • Resource Load Chart
  • Baselines saving and comparing
  • Generation of PERT Chart
  • PDF and HTML Reports
  • MS Project import/export with file format MPX (*.mpx) and MSPDI (*.xml) (XML-based data interchange format since Microsoft Project 2002)
  • Exchange data with spreadsheet applications
  • WebDAV based groupwork
  • Project file format is XML
  • Vacation and Holidays management
  • Available in more than 20 languages
