Aptana Studio is a comprehensive tool that brings HTML, CSS and JavaScript support into a single integrated development environment.

The program includes a number of features that will speed up your web development. HTML, CSS and JavaScript Code Assist, for instance, helps you code faster and more accurately. Type a JavaScript object name - "document.", say - and Code Assist displays all its methods and properties, making it easy to choose the one you need.

You also get integrated code samples. A Snippets feature lets you quickly insert frequently-used chunks of code into your projects. Syntax highlighting keeps your documents more readable, and integration with Firebug for Firefox offers many useful JavaScript debugging options.

Aptana Studio can be extended in many different ways. It already includes many popular Ajax libraries: jQuery, prototype, scriptaculous, Ext JS, dojo, Spry, and YUI, for instance. You can add QuantumDB, giving easy access to local or remote databases. There are run-times for Ruby on Rails, Python and PHP, and more than 1,000 third-party plug-ins to add just about any functionality you might need.

And when your project is complete, transfer it to your server using built-in FTP support, or deploy it right away to Aptana's (subscription-based) Cloud service.
