Looking for an open-source replacement for Microsoft Outlook? How about the Linux equivalent of Adobe Premiere Pro? AlternativeTo suggests alternatives to popular applications and lets you filter the results by platform for easier review.
You can browse the AlternativeTo site for "most viewed" and "most liked" software (based on user input, natch), or search for specific titles.
Interestingly, AlternativeTo lists not only Windows, Mac, and Linux solutions, but also online alternatives. Thus, if you look up, say, Photoshop, you'll find Web tools like Picnik and Pixlr in addition to popular downloads like GIMP and Paint.Net.
You can also filter by license: free or commercial. And if you create an account, you can get in on the tagging, "liking," and alternative-suggesting action.
Curiously, the one thing missing from AlternativeTo is Microsoft Office -- perhaps because it's a suite and not an individual app? (Word, Excel, and PowerPoint are all there.) Even so, AlternativeTo is definitely a handy resource for anyone who's switching platforms or looking to save cash on software. [via gHacks]
