Ouisync offers a secure, peer-to-peer file-sharing application, enabling users to store, sync, and share files across devices without relying on centralized servers. It promotes privacy and user control by offering end-to-end encrypted data sharing with customizable permissions (read/write, read-only, blind).

Ouisync is particularly beneficial for collaborative projects, secure backups, and unrestricted access to shared content, even in connectivity-limited environments​​​​​​.
