<p>CodeWeavers supports the concept of open-source software. We believe that the success of open source software will bring forth new, exciting products and services. We also believe that open source software provides viable models for corporate growth.</p> <p>We believe it is important for any company that relies on Free Software to make sure their software community is vibrant and rich in its own right. To that end, we are the largest supporters of the Wine Project. We do all of our work on Wine directly against the upstream Wine project; we submit our work to Wine first. We also sponsor the annual Wine conference, and take great pains to make sure that we do everything we can to keep Wine a vibrant community.</p> <p>At the same time, we have to eat. Many of our own customers make their livings selling proprietary software. CodeWeavers believes that there is a place in the world for both models</p> <p>CrossOver, while composed primarily of an open-source core, also contains proprietary components that comprise some of our "value add." This allows us to differentiate ourselves against the free version of Wine.</p> <p class="text-end my-5"><a href="#projects" class="btn btn-cw-outline">View Projects We Support</a></p> </div> </div> </div> </div>   <div class="container-fluid logo-symbol-top border-bottom-0"> <div class="container py-5"> <div class="row"> <div class="col-12 text-center"> <h2 class="pt-4">Did you know?</h2> <p>When you purchase CrossOver, you are supporting open source as the majority of CrossOver development source code gets released back into the Wine project for everyone's benefit.</p> </div> <div class="col-12 text-center"> <a href="https://www.winehq.org/forums" target="_blank" class="btn btn-cw-outline">Join WineConf mailing List <i class="fa-solid fa-external-link-alt"></i></a> </div> </div> </div> </div>   <div id="projects" class="container-fluid dark steelwall"> <div class="logo-symbol-bottom"> <div class="container pb-5"> <div class="row py-5"> <div class="col-12"> <h2 class="text-center">Projects we contribute to...</h2> </div> </div> <div class="row"> <div class="col-md-6"> <div class="card card-cw transparent info-box card-cw-border-right-blue"> <div class="card-body pt-5 px-3"> <h2>Wine</h2> <p>Wine is an open-source project that provides a compatibility layer used to run Windows applications on other operating systems like macOS and Linux.</p> <a href="/wine" class="btn-cw-outline-wht">Learn how we support the wine project</a> </div> </div> </div> <div class="col-md-6"> <div class="card card-cw transparent info-box"> <div class="card-body pt-5 px-3"> <h2>Proton</h2> <p>Proton is a tool for use with the Steam client which allows games which are exclusive to Windows to run on the Linux operating system.

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.
