Google pushes Pro, Ultra, and free users from open-source Gemini CLI to closed-source Antigravity CLI

Google is phasing out Gemini CLI for free, Pro, and Ultra users starting June 18, along with Gemini Code Assist extensions and GitHub support.

Developers are being pushed to Antigravity CLI, a closed-source, agent-first tool with plugins for Gemini features, but it still lacks feature parity with Gemini CLI.

Early users say Antigravity has low quotas and burns through tokens quickly, raising concerns about usability.

Enterprise customers and users with API keys will still retain access to Gemini CLI.
