Private packages and organizations

Organizations is currently in beta, fill out the sign up form to request access.

With an organization you can publish and fetch private packages from and you can control exactly which users have access to the packages. To administer any organizations you are a member of go to the dashboard.

Add an organization to Mix

The organization’s packages are namespaced under the organization’s repository. Only members of the organization have access to the repository’s packages, to get access in Mix you need to authorize the organization with the mix hex.organization task. Run the following command to do so:

$ mix hex.organization auth acme

To run this command you need to have an authenticated user on your local machine, run $ mix hex.user register to register or $ mix hex.user auth to authenticate with an existing user.

Publishing a private package

To publish a package simply to your organization add the --organization flag to the $ mix hex.publish --organization acme command. You can also configure a package to belong to a specific organization, add the organization: "acme" option to the package configuration:

defp package() do
    organization: "acme",

You can publish documentation for private packages, but this feature is still in beta and they will currently not be visible on

Using private packages as dependencies

A private package can only depend on packages from its own repository and from the global "hexpm" repository where all public packages belong. You specify a package should be fetched from a specific organization’s repository with the :organization option on the dependency declaration, if this option is not included it is assumed the package belongs to the global repository. For example:

defp deps() do
    # This package will be fetched from the global repository
    {:ecto, "~> 2.0"},
    # This package will be fetched from the acme organization's repository
    {:secret, "~> 1.0", organization: "acme"},

Authenticating on CI and build servers

You can generate repository authentication keys manually with the mix hex.organization key task. This can then be used to fetch packages on your CI servers without requiring manual authentication with username and password.

Run the following command on your local machine:

$ mix hex.organization key acme
Passphrase: ...

Copy the returned hash and authenticate with it on your build server:

$ mix hex.organization auth acme --key 126d49fb3014bd26457471ebae97c625
