Cozy is a platform that brings all your web services in the same private space. With it, your web apps and your devices can share data easily, providing you with a new experience. You can install Cozy on your own hardware where no one profiles you.

It is the core server of the Cozy platform. It consists of a single process, the Cozy stack.

Full Cozy-Stack documentation here.

The Cozy-Stack is in charge of serving the Web applications users have installed from the application store.

It provides its services through a REST API that allows to:

• create, update, delete documents inside the database;
• authenticate users and client applications;
• send emails;
• launch jobs on the server. Connectors that import data from remote websites are some sort of jobs. Jobs can be one time tasks (sending a message) or periodic tasks. Some jobs, like the connectors, that require executing third party code on the server side, are sandboxed (we use nsjail for now).
• …

The Cozy-Stack also allows to access the database replication API, allowing to sync documents between the server and local databases, for example in mobile clients.

Two authentication methods are available:

• Web applications running on the server get a session token when the user log in;
• OAuth2 for other applications.

Feel free to open an issue for questions and suggestions.

You can follow the Install guide and the configuration documentation.
