CodeWeavers and Wine: A good pairing.

What is the Wine Project?

Wine is an open-source project that provides a compatibility layer used to run Windows applications on other operating systems such as macOS and Linux.

Wine works differently than other "emulation" software. Instead of running a version of Windows "in a bubble" inside your macOS or Linux environment, Wine is an intermediary. It translates Windows instructions into macOS or Linux instructions directly. That means when you open your Windows application, it will run faster and smoother than it would through an emulator.

How we support the Wine project

We contribute all of our work on Wine back to the Wine Project. In fact, CodeWeavers developers make up for two-thirds of the Wine commits. The majority of the development we do goes into Wine first before it becomes part of our commercial product CrossOver.
