About Cozy
Cozy is a platform that brings web services into one private space. Cozy Stack is the core server of the Cozy platform, and it runs as a single process. The project is written in Go, is developed by Twake Workplace, and is distributed under the AGPL v3 license. It lives in the self hosted personal cloud ecosystem, and it targets users who want to install software on their own hardware instead of relying on a third party profile.
