ActiveReportsJS and ActiveReports.NET offer similar functionality with some distinct differences. ARJS is a 100% front-end reporting solution, and because of that, it only offers connectivity to JSON Data Sources.
ActiveReports.NET, on the other hand, can be bound to JSON, SQL, CSV, XML, and more. However, AR.NET needs to be connected to a .NET project in order to work properly, but can still be used with popular frontend frameworks, such as React, Vue, or Angular.
