AppRecs!

AlternativeTo let you find new Windows, Mac, Linux, online and mobile software based on applications you already know instead of useless categories. AlternativeTo is a new approach to finding good software. Tell us what application you want to replace and we give you suggestions on great alternatives! Instead of listing thousands of more or less crappy applications in a category, we make each application into a category. Think of it like forever evolving blog posts about good alternatives to the software that youre not satisfied with. And the "blog posts" are generated by you through suggestions, comments and votes. »
