As open source software continues to grow in popularity, particularly with enterprises, the number of new open source projects started each year continues to climb. By some estimates the amount of open source code available nearly doubles every year.
More importantly, the quality of new projects has also continued to increase. Many newer open source projects are launched by commercial entities that can provide long-term support and are committed to updating their offerings on a regular basis.
For this list, we tried to find some of the best FOSS projects that have launched within the last couple of years. While a few of these have received some significant media coverage and/or have large userbases, many are emerging projects that haven't yet gained a lot of attention.
