    ICEcoder - Code Editor Awesomeness

    ICEcoder - Code Editor Awesomeness

    Browser based code editor, allowing you to code from anywhere

    ICEcoder is a browser based code editor, which provides a modern approach to building websites. By allowing you to code directly within the web browser, online or offline, it means you only need one program (your browser) to develop sites, plus can test on actual web servers. After development, you can also maintain the website easily, all of which make for speedy and smart development. Because it can be web based you can use it from any internet enabled computer with a modern browser and because it's built with commom web languages, you can customise it to your liking, integrating with online services. If you'd like to use it as a desktop code editor, no problems, you only need PHP 5.0+ (though 5.3+ is recommeded), so you can use on Linux and on PC via WAMP or XAMPP and Mac via MAMP (or another PHP installation). ICEcoder is provided under a free 14 day trial and $5 to continue using after the trial has ended. See more details, features and much more at https://icecoder.net
