Google Shuts Down Open-Source Gemini CLI on June 18, Pushes Users to Closed-Source Antigravity CLI

Google Developers Blog·high signal

As of June 18, 2026, Gemini CLI stopped serving requests for all free, Pro, and Ultra tier users, replaced by Google's closed-source Go-based Antigravity CLI (invoked via 'agy'), with free-tier quota collapsing from ~1,000 to roughly 20 requests/day. Google had merged 6,000+ community pull requests into the 105K-star open-source project over nearly a year before restricting it to enterprise licenses, drawing a 'bait-and-switch' backlash and breaking CI/CD pipelines that depended on it. Only Gemini Code Assist Standard/Enterprise and paid API-key users retain access.
