PMtool is a web based free online project management tool, developed to be distributed as free software for both business and personal uses. PMtool is based on the coding language PHP and the database language of MySQL, and requires only basic and free software to be installed on a server for it to run properly. It is distributed under the GNU General Public License, this means it is open source, and the code can be changed and improved by any one any where.

If you don't know much about web servers or computers in general it would probably be best to get a technician to install this, but after that's accomplished PMtool really is amazingly easy to use.

As it is web based, it uses a largely graphical user interface, this makes it simple for anyone to use, from the experienced programmer to the most techno phobic client. The learning curve when you start to use PMtool as an online project management tool is very shallow, and after just a few hours of using the tool, most people will know everything they will ever need to know about it. It will also export to an XML file, common to many free project management tools, however it doesn't require a specific file to be the input, this means the input can be changed from anywhere by anyone.

As PMtool is a free online web based project management tool, it means anyone connected to the internet can use it. This means you can use project members from across the globe with out any worries, as well as letting clients see exactly what you're up to. This global access may pose some minor security issues but over all PMtool is an excellent free project management tool, that can be used for any sized company over any time period and any project.
