Google AI Studio Starter Tier not available when publishing my app

Hello,

I am trying to publish a full-stack application created in Google AI Studio Build mode using the free Starter Tier.

My Google account is a personal Gmail account.

My Firebase project is currently on the Spark free plan and I have not configured Google Cloud billing.

When I click Publish in Google AI Studio, I only see:

  • Default Gemini Project
  • No billing setup
  • Set up billing
  • Refresh

Refreshing does not change anything.

The project is locked because it is required by Firebase.

Cloud Run has no services deployed.

I do not want to enable billing or add a credit card. I would like to use the free Starter Tier as documented.

Could you please check why the Starter Tier is not being provisioned for my account/project?

Google Cloud project:
gen-lang-client-0624308…

Thank you.
