Editor and Headless Modes

Editor

zune run game --editor

You can combine editor and server mode:

zune run game --server --editor

The built-in editor is intended for playtesting, scripting, building, and object editing.

Headless

zune run game --headless

Headless mode avoids graphics initialization where supported. It is the appropriate starting point for dedicated-server/automation workflows that do not require rendering.

Client-only runtime UI

zune run game --client

The repository describes client mode as removing core/editor UI for a game-client style run.
