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.
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.

We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
