Sailfish OS
Sailfish OS is a Linux-based mobile operating system. It is an continuation of the MeeGo operating system made by Nokia and Intel. While in the past Jolla has sold devices with Sailfish OS preinstalled, nowadays consumers need to install it themselves.
Sailfish OS applications are usually written in C++, Python or Rust and make use of the Silica widget toolkit, which is based around Qt Quick. Other programming languages and UI toolkits can also be used, but are not officially supported.
