GOOGLE has officially deprecated the Gemini CLI, transitioning developers to the new Antigravity CLI as of June 18, 2026. Individual users of Gemini CLI can no longer access the platform, although enterprise customers retain access temporarily. The migration to Antigravity CLI is necessary for various user groups, including Google AI Pro and Ultra subscribers, amid reports of an internal shift favoring the new tool.
Despite some features missing from Antigravity CLI compared to Gemini CLI, it is designed to import existing setups seamlessly, preserving installed skills, MCP servers, and agent profiles. Developers are advised to start planning their migration to avoid service disruptions.
