Frequently, Datamation publishes lists of free Linux and open source software. This time, we're doing something a little different: we’re highlighting outstanding commercial open source software.

Before we go any farther, we should define what we mean by "commercial open source software." As with many topics in the open source world, different people have very different opinions about what that phrase means.

Some argue that if an open source project has a commercial side it's not truly open source any more. Others hold that if you look hard enough, all open source software has some sort of commercial motive.

On this list, you'll find a variety of projects that are based on open source code and whose owners make money directly from their software. How they make that money varies: Many of the projects on the list have a "community" version that is available under an open source license and "professional" and/or "enterprise" versions that add features that are only available with a commercial, paid license.

Other projects offer the software for free, but require payment for support, maintenance, installation or other services. A few others charge for hardware products based on the software. And a growing group of organizations make money by hosting their open source software on a software-as-a-service (SaaS) basis.

This list doesn't include projects that simply request donations or those that make money only by selling hats, T-shirts and other gear emblazoned with their logo. We also left off projects that offered paid support as an afterthought or those with support and services available only from third parties.

Why put together a list of commercial open source projects at all? Many businesses find it preferable to acquire software under a commercial license because they are worried about some of the legal provisions of some open source licenses, particularly the GPL. In addition, many companies want reliable support and maintenance for their software and are willing to pay for it.

Home users are much less likely to pay for open source software, and as a result, the vast majority of the projects on this list are aimed at businesses rather than home users.

As always, if you would like to suggest a project that you think should be on our list, feel free to mention it in the comments section below.
