Sync-in is an open-source platform for storing, sharing, collaborating on, and syncing files while maintaining full control over your data.

Core Principles: Sync-in is built on open-source transparency, allowing you to host data on your own infrastructure for complete data sovereignty. It features security by design with granular permission systems, scalable architecture suitable for individual or enterprise use, and efficient performance with modern technology. You can access your files anywhere through browser, desktop client, or WebDAV.

Major Features:

The platform offers collaborative spaces where teams can work together with dedicated areas, autonomous creation, and fine-grained permissions based on roles. These spaces are naturally compartmentalized for security and regulatory compliance.

Desktop synchronization applications for Windows, macOS, and Linux automatically sync files between your computer and Sync-in servers, with the ability to connect to multiple servers and manage sync direction, frequency, and detailed logs.

Secure sharing capabilities allow both internal and external file sharing with granular permissions, secure links, access limits, expiration dates, and password protection for full control over document distribution.

The guest system and personal groups enable collaboration with external partners while maintaining control over their access, with autonomous group creation organized by project, client, or team.

Activity tracking provides real-time monitoring with in-file commenting, recent file views, and notification systems for effective collaboration.

An advanced file manager offers drag-and-drop functionality, window management, smart clipboard, offline task manager, gallery view, sorting, filtering, and enhanced viewer capabilities.

The smart search engine performs full-text searches across document content (not just filenames) supporting Microsoft Office, PDF, HTML, and plain text formats with keyword inclusion/exclusion.

OnlyOffice integration enables real-time collaborative editing of documents, spreadsheets, and presentations with native Microsoft Office format support while respecting defined permissions.

Finally, WebDAV integration allows you to mount spaces as network drives accessible from any device or application.
