Nokia supports a range of Open Source activities in research centers and development groups around the world. Projects, documentation and resources are hosted in the most appropriate ecosystem for fostering and growing each project. Some are hosted and managed by Nokia directly, while for many others Nokia is simply a contributor.

The first section lists the Core Projects which are currently receiving Nokia Investment. The remaining sections list other projects of interest to Nokia and the Nokia Developer community, and archived projects that were formerly of interest.


Core Projects

Qt Project
Cross-platform app and UI framework
Qt is a cross-platform application and UI framework for developers using C++ or QML, a CSS & JavaScript like language.

Qt, Qt Quick and the supporting tools are developed as an open source project governed by an inclusive meritocratic model.
Open source web browser engine
WebKit is a popular open source browser engine used in many standards-compliant browsers, including Safari, Google Chome etc.

Nokia uses WebKit in its platform browsers, and it is also the base of Qt WebKit.
Promoting Linux through education is a user supported community website whose mission is to promote Linux through education.

Nokia has had a close relationship with Linux as the base of its MeeGo and Maemo platforms, and through Qt and KDE.
