Over the past couple of years, Microsoft has, under the reign of CEO Satya Nadella, accepted open source like never before.

It’s a arresting shift for the Redmond giant, which commonly kept its trade secrets and able technologies behind closed doors. One major sign of that is new data from GitHub, which is home to some of the Web’s better collaborative code projects.

The company, which counted more than 5.8 actor active users on its belvedere over the past 12 months, noted that Microsoft topped the list of organizations with the most open source contributors.


With 16,419 contributors, Microsoft beat out Facebook (15,682 contributors), Docker (14,059 contributors) and Google (12,140).

Of course, this didn’t happen overnight. In October 2014, it open sourced its .NET framework, which is the company’s programming basement for architecture and active apps and casework – a major move appear introducing more developers to its server-side stack.

Since then, it’s open sourced its Chakra JavaScript engine, Visual Studio’s MSBuild accumulation engine, the Computational Networks Toolkit for deep acquirements applications, its Xamarin tool for architecture cross-platform apps and most recently, PowerShell.

It’s great to see Microsoft adopt and stick with this access to architecture tools and casework that developers can take advantage of, after having to invest heavily in closed systems – while also being able to accord to and advance them.

GitHub CEO Chris Wanstrath believes Microsoft is truly committed to the open source movement. In an account with Fortune, he noted, “The big .Net activity has more people alfresco of Microsoft accidental to it than people who work at Microsoft.”

It’s also worth noting that the company’s Visual Studio Code text editor made GitHub’s list of repositories with the most contributors. You can check out these lists, as well as other data from GitHub’s belvedere on this page.
