Mass CLI Overview

The Mass CLI is a powerful command line interface for interacting with the Massdriver platform. It is used to build and publish bundles, manage deployments, and more.


Manual Installation

To install (or update) the Mass CLI manually, download the latest release from the Mass CLI releases page.

Select the file that matches your operating system and architecture, i.e. for Mac OS users.

Unzip the mass file and move it to a directory in your $PATH, i.e. /usr/local/bin.


For Mac OS users, you will need to allow mass to run by opening the System Preferences app, clicking on Security & Privacy, and clicking on the Open Anyway button. You may need to do this a second time after attempting to invoke the mass command.
