I have an active Google AI Pro (5 TB) subscription on personal @gmail.com accounts. Antigravity IDE login fails at onboarding on all paid accounts I tried (more than one). Free accounts log in fine on the same machine and network.
What works:
- Google AI Pro subscription is active and shows correctly in Google One
- Gemini app and Google AI Studio work normally on the paid account
- Free (non-subscription) accounts complete Antigravity login successfully
What fails:
- Browser OAuth completes and redirects back to localhost successfully
- Then the onboarding POST request is rejected
Logs (Antigravity IDE, Windows 10):
auth.log:
[error] Error confirming user for service: Your account is not eligible for Gemini Code Assist for individuals at this time
cloudcode.log:
[error] Failed to make POST request: Your account is not eligible for Gemini Code Assist for individuals at this time
Already tried:
- Multiple paid accounts (same result), free account works
- Incognito / different browser session
- Sign out and fresh login, cleared auth state
- Checked Google Cloud Console: all projects are under “No organization” (no Cloud Identity / Workspace org attached)
- Accounts are personal, 18+, not Workspace
Environment:
- OS: Windows 10
- Antigravity IDE version: 2.5.5
- Network: home/office network, no VPN
Request:
Please check whether the Google AI Pro entitlement is being recognized by the Antigravity onboarding service, or advise on a manual eligibility review.
