About the Ubuntu project

We believe in fast, effective computing for everyone. Created by the open-source community and Canonical, Ubuntu is free to use and share, at home and in business.

The Ubuntu Promise

Ubuntu is free. Always has been and always will be. From the operating system to security updates, storage to software.

Ubuntu is fast to load, easy to use, available in most languages and accessible to all.

Ubuntu applications are all free and open source — so you can share them with anyone you like, as often as you like.

Ubuntu comes with full support and all kinds of services available worldwide.

Open-source software ›

Ubuntu is created by open-source developers because we believe that everybody should have access to the best possible technologies.

This passionate global community works together to continually evolve the best systems in the world and then make them available to everybody, absolutely free.

Ubuntu and Canonical ›

Ubuntu is backed by Canonical — the number-one Ubuntu services provider.

Companies can choose to receive expert training, support or consultancy for a fee that goes towards the continued development of Ubuntu.
