Secure, simple, and reliable self-hosted file sharing - fully managed by us. An open-source alternative to Google Drive with real-time collaboration, desktop sync, and mobile access.
OpenCloud is an open-source project that gives you a secure and private way to store, access, and share files. It is a modern, actively developed alternative to Google Drive and Nextcloud - developed in Go, built with a microservices architecture, and designed to run efficiently from a Raspberry Pi up to data-centre scale.
OpenCloud is developed by the Heinlein Group and is used as the file sharing and collaboration platform for organisations that need full data sovereignty. Server licence: Apache 2. Client licences: GPL. No CLA required.
