Being able to see the source means you can take Vuo apart to see how it works. Knowing how Vuo works can be particularly helpful if you're developing your own nodes for Vuo, or if you want to integrate Vuo into an application you're developing.

Having the Vuo Compiler and core node source code also means that you have access to the full stack of software used by your Vuo compositions — your compositions will not contain any black boxes that block your ability to understand what's going on.
