I build websites like I am sure many of you do. These are currently some of my favorite applications, of course I use many more than these but these are my core ones. What are your four core web development applications? These focus on web development 1. Aptana - This program rocks for writing Java Script and other web languages http://www.aptana.com/ Tie this one together with the next one and you have a powerful web building solution 2. CSSEdit - This program allows the similar look of Dreamweavers visual Css tools http://macrabbit.com/cssedit/ 3. MAMP - Allows you to build and test your websites on your local Mac without having to upload them to a live server. Well, it does much more than that but that is one of it's features. http://www.mamp.info/en/index.php 4. Hsoi - These are a set of plug-in's, I use one of these a lot. The main one I use let's me see the absolute path of a file through the contextual menu, pretty neat. http://www.hsoi.com/hsoishop/software/#CMPlugins These are four that I really like and use, what are your four?
