Sailfish OS (also styled as SailfishOS or abbreviated to SFOS) is a general purpose Linux used commonly as mobile operating system combining the Linux kernel for a particular hardware platform use, the open-source Mer core stack of middleware, a proprietary UI contributed by Jolla or an open source UI, and other third-party components.
Sailfish is being developed by Jolla, the Sailfish and Mer project communities, corporate members of the Sailfish Alliance and various open community members. The Sailfish community members makes development requests and decides development priorities by voting. The Mer project receives contributions from the Jolla and its community, and Mer is the source of middleware for Jolla, thereby continuous development and compatibility of all MER based projects is maintained.
The OS is shipped with the Jolla smartphone and tablet (the latter has been discontinued) and from other vendors licensing the OS. More or less unofficially the OS is being ported by community enthusiasts to third-party mobile devices including smartphones and tablets.
The OS is an evolved continuation of the Linux MeeGo OS previously developed by alliance of Nokia and Intel which itself relies on combined Maemo and Moblin. The MeeGo legacy is contained in the Mer core in about 80% of its code; the Mer name thus expands to MEego Reconstructed. This base is extended by Jolla with a custom user interface and default applications. Jolla and MERproject.org follow a to avoid the mistakes that lead to the MeeGo project's then-unanticipated discontinuation.
The main elements for Sailfish OS 2.0 include:
The Sailfish OS and the Sailfish software development kit (SDK) are based on the Linux kernel and Mer. Sailfish OS includes a multi-tasking graphical shell called "Lipstick" built by Jolla on top of the . Jolla uses free and open-source graphics device drivers but the Hybris library allows use of proprietary drivers for Android. Jolla's stated goal is for Sailfish to be open source eventually.
