Cozy Sync

Cozy Sync allows you to synchronize your Contacts and your Calendars from your Cozy with any device or software that supports CalDAV and CarDAV protocols.


We assume here that the Cozy platform is correctly installed on your server.

You can simply install the WebDAV application via the app registry. Click on ythe Chose Your Apps button located on the right of your Cozy Home.

From the command line you can type this command:

cozy-monitor install webdav


You can contribute to the Cozy WebDAV in many ways:

  • Pick up an issue and solve it.
  • Translate it in a new language.
  • Allow to sync only contacts with a given tag.
  • Allow to sync only calendars with a given tag.


Hacking the WebDAV app requires you setup a dev environment. Once it's done you can hack Cozy Contact just like it was your own app.

git clone

Run it with:

node server.js

Each modification of the server requires a new build, here is how to run a build:

cake build


Build Status

To run tests type the following command into the Cozy WebDAV folder:

cake tests

In order to run the tests, you must only have the Data System started.

Contribute with Transifex

Transifex can be used the same way as git. It can push or pull translations. The config file in the .tx repository configure the way Transifex is working : it will get the json files from the server/locales repository. If you want to learn more about how to use this tool, I'll invite you to check this tutorial.
