Open-source platform
Sync-in allows full control over your data and infrastructure.
Sync-in is an open-source collaborative platform designed to facilitate teamwork, strengthen communication, and provide a simple, sovereign, and durable solution — suitable for both individual use and organizational needs. It is intended for businesses, public-sector entities, and institutions seeking a solution that is controlled, scalable, and aligned with their operational requirements. Sync-in was initiated several years ago by the engineer Johan Legrand. Since the opening of its source code, the project has continued to grow and now benefits from the support of an active community. Used in production for several years in various environments, Sync-in continues to evolve with a focus on being useful, responsible, and community-driven.
