Is DraftSight (not 3DEXPERIENCE version) a browser-based and/or cloud based CAD product?

I just downloaded the product and am more familiar with AutoCAD and SolidWorks which are local installations. The system requirements seem way too low to be a local installation product, but I cannot seem to get a straight answer on this. The chatbot on the support site doesn't help either. I want to understand the product better to make an informed decision on hardware and internet requirements.
