Sailfish OS is a Linux-based operating system based on open source projects such as Mer and including a closed source UI. The project is being developed by the Finnish company Jolla.
The OS is shipped with the Jolla smartphone and tablet (the sale stopped in 2016 but devices are still supported with software updates) and from other vendors licensing the OS. The OS is ported by community enthusiasts to third-party mobile devices including smartphones and tablet computers. Sailfish OS can be used for many kinds of devices.
The OS is an evolved continuation of the Linux MeeGo OS previously developed by an 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 meritocratic system to avoid the mistakes that led to the MeeGo project's then-unanticipated discontinuation.
The Sailfish OS SDK was announced at the Slush Helsinki conference in 2012, and the alpha was published in February 2013. The SDK, installation and coding tutorials are available for free download from the Sailfish OS website despite the overall license not being open source.
Sailfish 3 is ready for corporates
Sailfish 3 is a secure and efficient, open source-based mobile platform designed mainly for a multitude of corporate solutions. It has a deeper level of security including features, such as Mobile Device Management (MDM), fully integrated VPN solutions, enterprise WiFi, data encryption, and better and faster performance. With Sailfish 3, Jolla is also perfectly equipped to cater to all needs of different governmental and corporate clients.
In September 2015, version 18.104.22.168 "Eineheminlampi" was released, which added the main elements of the revamped Sailfish OS 2.0 user interface.
Sailfish 2.0 was launched with the Jolla Tablet, and existing devices, both smartphones, and tablets, from Jolla's official distribution channels, are supported with an upgrade to Sailfish 2.0 and following updates.
In May 2016 Jolla announced the Sailfish Community Device Program, supporting developers and members of the Sailfish OS community.
The aim of the Alliance is to offer unique differentiation opportunities and sustainable competitive advantage for OEM and ODM manufacturers, chipset providers, operators, application developers, retailers, and other interested insides. Sailfish 3 adds a host of new features and improvements to the user experience: the OS has a new fresh look, a new top menu, new keyboard gestures, new camera functions, data encryption improvements, and USB On-the-Go storage, just to name a few. The third generation also brings a clear improvement to the OS performance: the rewritten way to launch apps and load views, and the upcoming Qt upgrade improves the UI performance significantly.
Sailfish Alliance is the open alliance established in 2011 by Jolla company to support the MeeGo ecosystem with new products, services, and business opportunities around or using Sailfish OS, a Linux operating system combining mer with proprietary components from Jolla and other parties, for various purposes and mobile devices. And to continue the development of the Linux MeeGo ecosystem, which the Sailfish OS is a part of.
The alliance is seen as a competitor to other groups like Android's Open Handset Alliance.
