Install
- Install the official Apple silicon Antigravity.app first.
- Download the manager ZIP, unzip it and move “Aether Antigravity Multiplexer.app” into Applications.
- Open the manager, click “Create Instance”, and complete Google sign-in in the dedicated page that opens.
Upgrading from 0.2.1 to 0.3.0 or later requires one manual install; later versions update in-app.
Upgrade all copies
After the official Antigravity updates, click “Upgrade All Copies”. Save your work in each copy first; the manager verifies and backs up before replacing each app. Keep the backups until you've confirmed accounts and projects are fine.
If the official app moves to a version that hasn't been adapted yet, creating and upgrading pause until the manager is updated.
Clear a copy's workspace
When a copy is stopped, choose “Clear Workspace…” from its menu and enter its full name. This permanently clears all data in its ~/.gemini-N directory, including hidden files. The app, other data folders, separate login file and upgrade backups remain. This cannot be undone and does not sign you out.
Terms and boundaries
Google's current terms restrict copying or modifying its software. This tool contains only its own code and does not include or distribute Google software. Generated copies are ad-hoc signed for local use only — do not distribute them.
Report an issue
Configure automatic follow-ups
Enter a follow-up prompt in the instance Auto-Pilot settings, then choose the idle interval and maximum rounds. Verify the target with a test send before enabling. A limit of 0 means unlimited rounds.
Handle questions in the affected instance when attention is requested. Stalled tasks remain waiting. Pause through instance settings or the command palette.
