There are plenty of open source applications/software that can help you tremendously as a web designer. Open source projects are great not only because of their price tag (free), but also because of the passionate community that typically forms around them. In these economic times, it’s often a worthwhile endeavor to see places where you can conserve, and open source alternatives are a good place to start looking.
There are a variety of tools here that include source code, WYSIWYG, and graphic/image editors, as well as useful software utilities that can improve your task management and production processes.
