Google is replacing its open-source Gemini CLI tool with the new closed-source Antigravity CLI, with most free and paid consumer users losing access to Gemini CLI on June 18, 2026, while enterprise customers and those with paid API keys are exempt. Developers have reacted angrily to the switch, citing the lack of open-source code for Antigravity CLI, reported usage limit issues, and concerns that open-source community contributions were used to build a proprietary replacement. Google has acknowledged there will not be full feature parity at launch and that Gemini CLI will continue to be maintained, but only for paying enterprise customers.
