OpenCloud is an open-source, self-hosted file-storage and collaboration platform developed by the Heinlein Group. It is descended from ownCloud Infinite Scale and rewritten in Go, providing file management and sharing for teams and organizations without requiring a separate database instance or schema migrations. The platform supports optional full-text search, browser-based document editing through an integrated office suite, access controls, two-factor authentication, encryption, and file versioning. It is available for on-premises operation or as a SaaS offering through selected partners, with a cloud-native architecture intended for large data volumes and growing teams.
