It's a self-contained application using the Dear ImGUI library rather than a bloated framework, and is designed for a single language. It's not simple compared to the likes of vi, sure, but it's almost certainly many less lines of code and much more architecturally simple than just about any other (popular, in-use) IDE out there.
