OpenCloud is an open source platform for file management, sharing, and collaboration designed for organizations that need control over their data. It focuses on simple operation, strong security, and integration into existing IT environments.

Key Features

• File management with sharing links and permission controls
• Real-time collaboration features and integration with an office suite
• OpenID Connect authentication with support for external identity providers and an embedded identity provider
• Security features such as encryption, two-factor authentication, and versioning to help recover from unwanted changes
• Designed for on-premises operation and environments with strict compliance requirements

Use Cases

• Internal file sharing and collaboration for teams in companies and public institutions
• Secure data rooms for projects, research groups, or cross-department collaboration
• Replacement for proprietary EFSS solutions in sovereignty-focused IT stacks

Limitations and Considerations

• The backend stores data on the filesystem and does not rely on a traditional database, which may influence scaling and backup approaches depending on your deployment model

OpenCloud is a strong fit for organizations seeking a modern, open source EFSS and collaboration solution with OIDC-based authentication and enterprise-oriented security controls. It is particularly suited to deployments that prioritize data sovereignty and straightforward integration.
