Earlier this week I was looking for a nice HTML editor for Eclipse to help ease life when using PyDev with a Django project. I didn’t have much luck, other then finding a few syntax coloring tools that were HTML aware. That changed today when I found Aptana: The Web IDE. It’s a free, open source IDE for HTML, JavaScript, and CSS, built on Eclipse (available as a stand-alone application, or an Eclipse plugin) that offers target-browser aware code assist and syntax checking. The site includes some great screencasts to demo the product (and an interesting use of a .tv domain name.)
Though it’s officially unsupported on Eclipse 3.2 (they only support 3.1), it seems to work just fine in my environment.

[Minor update: Aptana ran fine on my OS X machine, but crashes hard on my AMD64 Ubuntu Dapper box running Eclipse 3.2.]
