The only Linux-native operating environment built from the ground up for convergence.
What is lomiri?
Lomiri is a free and open-source, next-generation GNU/Linux operating environment designed for convergence. Originally developed as Unity 8 and now maintained by UBports, Lomiri runs the same operating system and software across phones, tablets, laptops, and desktops.
Instead of separating “mobile” and “desktop” experiences, Lomiri adapts its interface to the device you’re using. Touch-first and intuitive on small screens, powerful and productive on larger ones, while keeping a single, consistent Linux foundation underneath.
Convergent User Interface
Lomiri dynamically adapts its layout, interaction model, and window behavior depending on screen size and input method (touch vs keyboard/mouse), using the same codebase across phones, tablets, laptops, and desktops.
Wayland-based, Security-first Architecture
Lomiri is a fully Wayland-based shell environment, relying on Mir as a Wayland compositor, enforcing application isolation and preventing global access to keystrokes, cursor position, and screen contents.
Standard Application Suite
Lomiri ships with a coherent set of core applications (browser, terminal, file manager, messaging, media, utilities, etc.) designed for daily usability.
Modern by Design
Lomiri offers a fully open-source, privacy-respecting alternative to closed mobile and desktop ecosystems.
True convergence
One operating environment that seamlessly adapts from phone to desktop, eliminating the need for separate platforms.
Freedom from Big Tech
Built on Wayland, Mir, and Qt, Lomiri is designed for today’s hardware, security expectations, and performance needs.
Why Lomiri Matters
Modern computing is fragmented. Mobile devices are locked into closed ecosystems, while full GNU/Linux power is mostly confined to desktops. Lomiri bridges that gap. It makes convergence real: a phone can become a desktop when you connect a screen and keyboard, without switching platforms or giving up freedom, privacy, or open software.
