A wide range of supported devices

dahliaOS provides a fast and stable experience on nearly every computer, from a 2004 desktop tower to the latest generation of mobile notebooks. Our dual kernel approach allows users with new(er) hardware to take advantage of the Zircon Kernel, while maintaining support for older devices using the Linux Kernel.


Internet Recovery

If something goes wrong with your system, dahliaOS will automatically download and boot from the latest image to help you get back up and running.

Powered by the best of Fuchsia and Linux

To ensure the widest range of support, dahliaOS provides builds based on both the Zircon and Linux kernels. Both images provide the same great desktop experience.

Effortless multitasking

dahliaOS features a brand new window manager, built from the ground up and designed to adapt between mobile and desktop platforms.

Optimized for every platform

Powered by the Buildroot build system, dahliaOS packs itself into a tiny 160 MB image file*, using only 199 MB of RAM when idle!

Free and open source

dahliaOS is licensed under the Apache 2.0 license, and all of our source code can be found on Github.
