KOffice

KOffice was a free and open-source office suite developed by the KDE community. It was part of the KDE Desktop Environment and aimed to provide a comprehensive set of applications for word processing, spreadsheets, presentations, and more. The suite's primary applications included KWord for word processing, KSpread for spreadsheets, and KPresenter for presentations. It also featured KImage for image editing and Karbon14 for vector graphics.

KOffice was designed with interoperability in mind, aiming to support various file formats, including Microsoft Office formats, though this was an ongoing development effort. It emphasized a user-friendly interface that was consistent with the overall KDE desktop experience. Development of KOffice was often driven by the goals of the KDE project, focusing on integration and providing a complete desktop solution.

Over time, the development of KOffice evolved. In 2011, the project announced a shift in strategy, with the core components of KOffice being spun off into a new project called LibreOffice, under the umbrella of The Document Foundation. While KOffice itself continued in a reduced capacity, the majority of its codebase and development efforts were redirected to LibreOffice, which has since become one of the most widely used free and open-source office suites. The original KOffice project saw diminished activity as its core technologies were absorbed into LibreOffice.
