ownCloud
Self-HostedOpen-source file sync & share platform for self-hosted data control
Overview
ownCloud is an open-source file synchronization and sharing tool that lets you self-host your data, ensuring full privacy and ownership. It supports cross-device sync (desktop, mobile, web), end-to-end encryption for sensitive files, and version control to recover previous versions. Deployment options include Docker Compose (simplified setup), manual LAMP stack installation, or cloud instances. Features like fine-grained access controls (user roles, share permissions) and integration with office suites (Collabora Online) make it ideal for personal or business use. It replaces proprietary tools with self-managed control over your files.
