Choose Gemini CLI if you want an open-source terminal agent for Gemini that you can authenticate with an API key, Vertex AI or a paid Google plan, but note unpaid and Google One users were moved to Antigravity CLI.
Gemini CLI is open source under Apache 2.0, so the cost sits in how you sign in. The plans page lists Free (Google account) at $0, Google AI Pro, Google AI Ultra and the Google Developer Program, plus two usage-based routes: an AI Studio API key billed pay as you go and Vertex AI billed through Google Cloud. The plans page shows no USD price for Pro, Ultra or the Developer Program, so we cannot quote a monthly figure for them.
The free route comes with a warning. The site says unpaid-tier and Google One users were moved to Antigravity CLI on June 18, 2026, so check that the free Google account login still works for you. Paid Google plans and API billing are the documented ways to higher limits. API-key and Vertex AI usage bills separately, and free-tier API data may be used to improve Google products.
