Antigravity IDE onboarding fails with "not eligible for Gemini Code Assist for individuals" on Google AI Pro personal accounts

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.

Hi @Yossra_Khalifa,

Welcome to the Forum,

Could you please try logging in using either the latest Antigravity 2.0 or the Antigravity CLI to see if you can log in successfully with the same account and start a new conversation?
