Adobe Device Central costs 550 US Dollars.  But the best things in life are freeware.  So today I’m sharing a list free tools for web developers to test and check their websites on mobile phones and other devices, such as iPad.  You’ll find emulators and simulators, analysis tools and Firefox extensions. If you use these tools, they will work as Adobe Device Central alternatives.

A couple of weeks ago, I made a collection of Tools for Testing Your Websites on various PC platforms. This is a follow-up resources list for mobile devices. Hope you’ll like it.


iPhoney is not an iPhone simulator but instead is designed for web developers who want to create 320 by 480 (or 480 by 320) websites for use with iPhone. iPhoney gives you a pixel-accurate web browsing environment—powered by Safari—that you can use when developing web sites for iPhone. It’s the perfect 320 by 480-pixel canvas for your iPhone development.
