unity-cli by youngwoocho02 is an open-source command-line tool that lets agents control the Unity Editor.
unity-cli lets any agent type commands at the editor you have open. Satura Space shows you the running game, and adds four things it doesn't have.
The agent sets up the moment and opens Unity's real Inspector on just the fields that matter. You tune it by feel.
Run agents in parallel, each in its own side Unity project, streamed beside the game. Open a Tuner on any of them.
Up to four synced editors, each streamed with its own input. One handle call starts every player on the same frame.
Ask about anything you don't know. Drift walks you through the UI, points at the field and explains what to tweak in the Inspector.
