SailfishOS logo



An independent, partner friendly operating system that fosters innovation. It’s unlike what you’re used to. But once you get the hang of the gesture based Sailfish OS, you’ll never want to go back. The highly adaptive Sailfish OS contains Open Source Software building blocks, welcoming collaboration or simply, free-time hacking.

Jolla logo



The world doesn’t need yet another smartphone – it needs a new way of thinking. That’s why Jolla was born. We want to challenge the dominant perceptions. We want to create an innovation platform for ideas, opportunities and openness. Open Jolla, a new way of thinking.
