Overview
Description

Seafile is an open‑source, self‑hosted solution that lets teams sync, share, and collaborate on files across devices. It offers fast synchronization, granular permission controls, and optional end‑to‑end encryption for secure private cloud storage. The platform provides web, desktop, and mobile clients, plus integration with LDAP/AD and third‑party services, making it suitable for enterprises, SMEs, and developers who need reliable on‑premise file management.

Sync-in is a self-hosted, open-source file storage and synchronization platform built with TypeScript, positioned as a data-sovereign alternative to Dropbox, Google Drive, and Nextcloud. It pairs desktop sync clients for Windows, macOS, and Linux with real-time collaborative document editing through Collabora Online and OnlyOffice.
