Open Source Software List: The Ultimate List

The ultimate open source software list, including games to website editors, office tools to education – nearly 1,300 open source software applications.
(Page 1 of 10)

Every year, we like to offer a roundup of all the open source software we've featured in the lists we publish throughout the year. This time we're including nearly 1,300 projects (1,297 to be exact) in a wide range of categories.

We have quite a few new additions this year, particularly in the Internet of Things and cloud computing categories. And we dropped off several projects that haven't been updated in quite a few years.

Please note that this is not a ranking; projects are arranged into categories and then alphabetically within the categories.

If you know of other open source projects that you think we should highlight on our 2016 lists, please feel free to note them in the comments section below.
