Update January 22, 2013: This article was originally posted February 7, 2008. Since then, it has been one of our most popular articles here at WHdb.com. In light of this, we have decided to give this article an update for 2013: we cleaned out some obsolete links and added a New for 2013 section. Enjoy! Not every proprietary program can drive a person crazy, right? Some, like Adobe Photoshop, are superb tools for anyone to use. But, the fact that these tools are proprietary can drive open source fanatics up a wall. It’s not the price of the software that makes the real difference (although that’s one reason to migrate from one software to another for many people), it’s the idea that proprietary software comes with boundaries that keeps the user experience confined to…well, being the user. That’s enough to drive any developer crazy. The following fifty sixty proprietary programs are listed in no particular order within broad categories along with their open source alternatives. In some cases you could probably write your own book on frustrations with the proprietary programs shown here. In other cases, you’ll discover that the open source alternative isn’t quite up to snuff yet. And, in other cases still, you’ll learn that some proprietary programs are real gems, but that the open source advocate can replace those gems with equally shiny objects from the open source repertoire. Jump to: Operating Systems & Web Browsers | Office Suites | Office Tools | Productivity | Graphic Programs | Web Editors | Desktop Publishing | Communications | Media | Utilities | Security | Financial | New for 2013 All of these open source alternatives have been around since before 2013, but it was in 2013 that they made our list. Some are newer Web-based or mobile technologies that hadn’t hit the mainstream five years ago when we first published this article but are household names today. Others have simply earned their way onto our list by enduring time. I’m Josh Weikel, editor and admin of WHdb. Over the years, I’ve learned (sometimes the hard way) that choosing the wrong hosting plan can leave you without an important site feature you need, or have you overpaying for services you don’t need. I built WHdb to make it easier to find a host that just works. You won't find any fake reviews or questionable ratings systems here - just accurate, useful info. Source.
