About Sync-in

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.

Project origins​

Sync-in was initiated several years ago by the engineer 🇫🇷 Johan Legrand (LinkedIn · GitHub).

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.

What we offer​

Sync-in provides a concrete response to the needs of organizations through:

  • a modern, accessible collaborative platform designed for everyday use;
  • an open and controllable solution that anyone can deploy, adapt, or integrate;
  • professional guidance to ensure reliable and sustainable adoption.

To support the long-term development of the project and meet professional requirements, we offer partnerships, sponsorship opportunities, dedicated support, and professional services for organizations seeking a free, reliable, and transparent alternative.

Our values​

The development of Sync-in is guided by several key principles:

  • Open-source: the code is public and can be audited, adapted, and improved.
  • Digital sovereignty: you retain control over your data, infrastructure, and technological choices.
  • Transparency: the project’s workings and evolution are documented and accessible.
  • Responsibility and accessibility: the solution is designed to be useful, sustainable, and suitable for organizations of all sizes and contexts.

A clear framework​

Sync-in is released under the AGPLv3 license, ensuring access to the source code and the ability to use or adapt the solution — including in hosted-service scenarios — in compliance with the license.
The Sync-in® name, logo, and visual identity are protected trademarks, and their use in a commercial context is governed by our Trademark Policy and partnership agreements.
