SFMC Companion is a Chrome extension developed by Cameron Robert. It is a free tool designed to support navigation and discovery in Salesforce Marketing Cloud by creating connections between objects.

This extension allows users to quickly navigate through their Marketing Cloud objects, such as Automations, Queries, and Data Extensions, to find where they are saved, what activities are using them, and what other objects they interact with. For example, by clicking on a Data Extension, users can see what Queries target that Data Extension and what Queries reference it in their code. Similarly, by clicking on a Query, users can view a list of all the Data Extensions referenced in the Query, as well as the details of the target Data Extension and all the Automations that are using that Query.

SFMC Companion also provides users with the ability to search for objects by name, making it easy to quickly find what they are looking for. Additionally, users can export detailed inventories of objects in their Marketing Cloud instance using the built-in object reporting feature.

It is important to note that SFMC Companion is limited by the user's roles and permissions in Marketing Cloud. Users will only be able to load and navigate objects that they have permission to access.

Please keep in mind that SFMC Companion is currently in the Alpha Release Stage and is provided "as-is," with no warranty or guarantee. It is not an official product of Salesforce and is not representative, endorsed, or supported by Salesforce in any way.
