XrmToolBox is a Windows application that connects to the Common Data Service for Apps (CDS). Dynamics 365 Customer Engagement (CE) applications, like Dynamics 365 for Sales, Service or Talent also use the Common Data Service for Apps as their foundational data service. XrmToolBox, provides tools to ease customization, configuration and operation tasks for anything built on CDS, including Dynamics 365 CE (formerly CRM) and model-driven PowerApps. It is shipped with more than 30 tools to make administration, customization or configuration tasks easier and less time consuming. And more than 100 other tools are available in the Tool Library.
XrmToolBox is a free tool and will remain like this but, there are a couple reasons you might want to donate.
