Organizations seeking complete data sovereignty over their documents, spreadsheets, and shared project folders can deploy OpenCloud as a self-hosted workspace for file sync, sharing, and real-time collaboration across web, desktop, iOS, and Android clients. Teams organize departmental assets inside dedicated Spaces where files belong to the project rather than individual user accounts, ensuring continuity when personnel change and enabling delegated space managers to assign granular read, edit, or upload permissions. Through built-in WOPI integration with Collabora Online, multiple colleagues can co-edit Microsoft Office and OpenDocument files simultaneously in the browser with automatic conflict locking and version history recovery. External partners and clients can access files via password-protected public links with custom expiration dates or upload deliverables into write-only File Drop folders without seeing existing directory contents. Cross-organization collaboration works seamlessly over the Open Cloud Mesh federation protocol, while full-text and tag-based search locates documents across personal and shared drives in seconds. Client devices synchronize changes in real time with support for virtual files on demand, resumable chunked uploads, and offline mobile access with camera document scanning. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.
