ownCloud is a secure, open-source platform for synchronization, sharing, and collaboration on content, enabling teams to store, share, and work on their files and documents through a single access point. Its new generation, ownCloud Infinite Scale (oCIS), is built on a modern architecture written in Go, designed for performance and scalability, with no external database required to get started.

The platform offers real-time collaboration (simultaneous document editing, shared presentations, file annotation) through its office integrations with OnlyOffice, Collabora Online, and Microsoft 365. The Spaces feature provides project folders to facilitate remote team work, with flexible access control (password protection, expiration dates, detailed permissions).

ownCloud can be deployed on-premises, in a data center of your choice, or in hybrid mode, making it a suitable solution for organizations that want to maintain control over their data. It targets businesses looking for a self-hosted alternative to public cloud services.
