SAVIHost is described as 'Lets you basically turn a VST instrument plugin into a standalone app. It's a very simple VST host that loads up a similarly named VSTi dll file and lets you interact with the plugin as if it's been loaded into a DAW complete with keyboard and extensive options' and is an app. There are eight alternatives to SAVIHost for Windows, Mac, Linux and BSD. The best SAVIHost alternative is Carla, which is both free and Open Source. Other great apps like SAVIHost are Light Host, VSTStuff, Kushview Element and Pedalboard 2.
