dotProject : the Open Source Project Management tool.
dotProject is built using free open-source applications and is produced and maintained by a small, but dedicated group of volunteers. dotProject is programmed in PHP, and utilises MySQL for a backend database (although other databases such as Postgres could also be used). Our recommended server platform includes Apache 1.3.27, PHP 4.2+, and MySQL. In the spirit of free, peer-reviewed, open source application development, we would also encourage you to use an operating system such as Linux, FreeBSD, or OpenBSD. However, additional operating systems such as Windows, Mac, and other flavours of *nix are also supported.
