ownCloud is a free and open-source software project for content collaboration, file-sharing, and file-syncing. It's usable in distributed and federated enterprise scenarios.

ownCloud supports extensions including Collabora, OnlyOffice, Microsoft 365 and Microsoft Online Office, as well as synchronization of calendars and contacts. Most of ownCloud is published under AGPL and GPL licenses, except for some enterprise extensions.

As of late 2023, organizations using ownCloud include CERN, the European Science Cloud, the Bavarian school cloud, and the SCIEBO platform.

History

The ownCloud project was launched in 2010 by Frank Karlitschek, who shortly afterward founded the company of the same name together with Markus Rex and Holger Dyroff. In 2016, ownCloud CTO Karlitschek left the company and founded the fork Nextcloud.

At the end of 2023, ownCloud merged with Kiteworks; however, ownCloud claims its code will remain open-source.

Versions

ownCloud is available in two versions: ownCloud 10, which is built on PHP; and Infinite Scale, which is built on Go.
