OpenCloud is a self-hosted platform for managing files, sharing documents and collaborating with other users. It gives individuals and organisations control over their information while providing the convenience associated with commercial cloud storage services.
The software is designed around personal files and collaborative spaces, making it suitable for teams that need to maintain shared document collections. Its architecture combines a Go-based backend with a browser interface and integration facilities for document editing and other services.
This is free and open source software.
Key Features
- Collaborative spaces provide dedicated project folders with configurable membership and access permissions.
- Synchronise files between computers and the server, with support for mobile and desktop clients.
- Share individual files or folders using public links or invitations to registered users.
- File-drop functionality allows external users to upload documents without gaining access to existing files.
- Advanced search supports filenames, file contents, metadata and additional filtering options.
- Search backends include Bleve and OpenSearch, providing alternatives for different deployment requirements.
- Real-time collaborative Markdown editing allows multiple users to work on the same document simultaneously.
- Collaborative editing includes participant indicators, mentions and rich editing controls.
- Version history helps users inspect earlier document revisions and restore previous content.
- Integration with Collabora provides browser-based editing for compatible office documents.
- Image previews, keyboard shortcuts and drag-and-drop operations simplify everyday file management.
- Supports container-based deployment and configuration for organisations operating their own Linux infrastructure.
