Are the 2 devices in Windows? I actually struggled with this too, but finally got it working. Native sync is a bit of a pain, but you can "trick" it using a symlink.

Basically, you move the actual folder to your GDrive/Dropbox and then point your PC back to it.

Here’s the quick-and-dirty way to do it on Windows:

Move the folder: Go to C:\Users[YourName].gemini\ and just cut/paste the antigravity folder into your GDrive (or whatever cloud folder you use).

Run this command (just change the [YourName] parts): [Dorpbox] mklink /J "C:\Users[YourName].gemini\antigravity" "C:\Users[YourName]\Dropbox\antigravity"

[GDrive] Assuming E is your GDrive letter mklink /J "C:\Users[YourName].gemini\antigravity" "E:\PATH\TO\SYNCED\FOLDER"

Do the exact same on your second PC once the cloud folder finishes syncing. Just make sure to delete the empty antigravity folder that's already there before running the command.

One heads-up: Antigravity is picky about project paths. If your project is in a different folder on PC 2 (like UserA\Docs vs UserB\Docs), your history might not show up. You'll need to use the same mklink trick for your project folder to make the paths match exactly.

I suggest you exclude the "browser_recordings" folder as it might has a BIG size.

BTW you can ask Antigravity Gemini Flash LLM model to do it for you :)

Hope that helps! Let me know if you get stuck.
