ownCloud

ownCloud is an open source file synchronization and sharing platform originally created in 2010 by Frank Karlitschek as a KDE community project, later incorporated as ownCloud GmbH in Nuremberg, Germany. As one of the pioneering self-hosted cloud storage solutions, ownCloud laid the groundwork for the European open source file sharing movement. While Nextcloud was forked from ownCloud in 2016, ownCloud has continued to evolve independently with a strong focus on enterprise customers and large-scale deployments.

The platform offers file synchronization across desktop and mobile devices, collaborative document editing, secure file sharing with granular permission controls, version history, and integration with existing enterprise infrastructure including LDAP, Active Directory, and SAML. ownCloud Infinite Scale, the latest generation of the platform, is built on a modern microservices architecture using Go, delivering improved performance and scalability compared to the original PHP-based platform.

Headquartered in Nuremberg, Germany, ownCloud serves a wide range of enterprise customers, research institutions, and government organizations that require full control over their data. The platform is deployed by organizations like CERN, the European Commission, and numerous German state governments. For European enterprises seeking a proven, mature file sync platform with deep enterprise integration capabilities and complete data sovereignty, ownCloud remains a trusted choice.
