Why not call it "standalone app" (Chrome-less! though that might be confusing for other reasons.)
1. In-browser Chrome extension with a UI (Postman legacy app)
2. In-browser Chrome extension without a UI (Postman Interceptor)
3. Stand-alone/desktop Chrome app (can be run withput Chrome)
4. Command line tool (newman - runs the same runtime as Postman)
5. Stand-alone/native apps that can be installed (where most of the debate on this thread is)
6. Server-side runtime
We chose to use "native" because it avoids the confusion with the existing Chrome desktop app and informs people about the advantages of this version v/s the previous version in one word.
