Google Gemini CLI Shut Down, Antigravity CLI Mandatory — No 1:1 Feature Parity at Launch

Google's Gemini CLI stopped accepting requests from free, Pro, and Ultra users on June 18 as mandatory migration to Antigravity CLI takes effect. Antigravity CLI, rewritten in Go, replaces Gemini CLI's 1,000-requests-per-day limit with a weekly compute-based cap and adds asynchronous multi-agent background workflows. Google acknowledged there will not be 1:1 feature parity at launch, and developers who built CI/CD pipelines around Gemini CLI commands must update their tooling immediately. Enterprise Code Assist Standard and Enterprise license holders retain Gemini CLI access unchanged.
