Vicasso's AppExchange Applications are fully compatible with the My Domain feature in Salesforce.

Please note that enabling My Domain is required for the use of any Lightning Component.

We do not include any hard-coded domain URLs within the application code, and there isn't any special configuration required beyond the documented steps to configuring the respective application.
