Sync-in

Sync-in is a French open-source platform for storing, sharing, synchronizing, and collaborating on files. It addresses the need to keep files readable on the file system, apply consistent access rules across all access methods, and retain control over data and infrastructure, including in self-hosted deployments.

Core capabilities include collaborative Spaces for organizing content by team or project, protected share links with granular rules, real-time editing of documents, spreadsheets, and presentations, full-text search, an advanced file manager with drag and drop, guests and personal groups, activity tracking with comments and notifications, desktop synchronization clients for Windows, macOS, and Linux, and WebDAV integration. A unified permission model applies the same access logic across the web interface, WebDAV, synchronization, editors, and APIs.

Sync-in is released under the AGPLv3 license and targets individuals, businesses, public-sector entities, and institutions. It can be deployed on controlled infrastructure, with hosting options and enterprise support available for architecture guidance, integrations, performance, and ongoing governance.
