frontend usually still proprietary
Open Source - excellent tools, global collaboration, developed by experts located throughout the world, solutions often readily available, good performance on internet, networkable, www runs on Apache - which is OS! functionality developed very quickly by open source community, customizable, source code available
Proprietary - more user friendly, feature rich
