Chromium OS
Google
Chromium OS is an open-source initiative focused on creating an operating system that offers a quick, user-friendly, and secure experience tailored for individuals who primarily engage with the internet. Users can access the project's design documentation, download the source code, and participate in its development. Rather than being merely a browser, we envision Chromium as a web-centric tabbed window manager or shell. We strive to keep our user interface clean, similarly to how we would hope that major companies like Apple and Microsoft would refrain from cluttering the standard window frames of their applications. In this model, tabs serve as the functional equivalent of a title bar in desktop applications, while the tabbed interface itself acts as a practical tool for organizing groups of applications. Looking ahead, there is potential for the introduction of alternative tab types that may not feature the traditional browser toolbar, further enhancing user customization and experience. This evolution of the interface reflects our commitment to adapting to user needs and preferences as they continue to change. -

While LibreELEC is centered around Kodi, it has also been forked to create a stable JeOS base for other projects like Plex Embedded, Lakka, and various IoT and maker initiatives. Users familiar with OpenELEC will recognize similarities in the software output, as both distributions operate Kodi with shared code, yet they diverge in their foundational principles. The governance of LibreELEC is managed by a project board that is elected from among the active team members, responsible for defining project objectives, establishing priorities, and making key decisions. This board plays a crucial role in ensuring that tasks are effectively assigned to volunteers. LibreELEC stands as a free and open-source software solution that aims to empower users and developers alike. The community-driven approach fosters an inclusive environment where contributors can thrive and share their innovations.

MidnightBSD
MidnightBSD
FreeIt encompasses all the essential software necessary for your everyday activities—such as email, internet browsing, document editing, gaming, and a plethora of additional applications. MidnightBSD, supported by a small yet passionate group of developers, aims to build an accessible operating system that is available for everyone to use at no cost. This system is compatible with x86, AMD64 architectures, and can also be run as a Virtual Machine. While the FreeBSD project has established a robust server operating system, it frequently neglects the usability and performance aspects required for desktop environments. It is crucial to customize scheduling, resource allocation, security measures, and application support to better serve desktop users. Many BSD-based projects are designed primarily for server use or older systems, and while some offer FreeBSD with a user-friendly graphical interface, they still suffer from an underlying server-oriented structure. Our decision to fork FreeBSD was not due to any conflict, but rather because we saw it as an exceptional foundation to build upon. Ultimately, our goal is to bridge the gap between server efficiency and desktop user experience. -
