TL;DR
Google will end support for Gemini CLI on June 18, 2026, replacing it with Antigravity CLI, a new platform designed for multi-agent workflows. Existing users are encouraged to transition now.
Google has announced that Gemini CLI will stop functioning on June 18, 2026, as part of its transition to the new Antigravity CLI platform, aimed at supporting multi-agent workflows.
In a May 19, 2026, announcement, Google stated that Gemini CLI and its associated IDE extensions will cease service on June 18, 2026. This change affects users of Gemini AI Pro and Ultra, as well as those utilizing Gemini Code Assist for individuals and GitHub organizations.
The company explained that the transition is driven by evolving user needs, which now favor a unified backend and multi-agent capabilities. The new Antigravity CLI, built in Go for faster performance, will retain core features such as Agent Skills, Hooks, Subagents, and Extensions, now as plugins. It will also share architecture with Antigravity 2.0, the upcoming desktop application, allowing seamless updates across platforms.
Existing enterprise customers with Gemini licenses or using Gemini Code Assist via Google Cloud will continue to have support, with access to Gemini models and API keys. Google encourages users to transition early and provides technical documentation and upcoming video tutorials to facilitate migration.
Why It Matters
This development is significant because it marks a strategic shift by Google towards a more integrated, agent-centric development platform. For developers and organizations relying on Gemini CLI, this means adapting to new tools that promise improved performance and multi-agent orchestration, potentially impacting workflows and project timelines.
The transition also reflects broader trends in AI development, emphasizing unified architectures and scalable agent systems, which could influence future product offerings and developer practices.

Background
Google launched Gemini CLI last year to bring AI capabilities into the terminal environment, quickly gaining popularity with over 100,000 GitHub stars and a broad community of contributors. The platform was designed for quick, grounded answers and building projects directly from the terminal environment.
However, user feedback indicated a need for more complex, multi-agent workflows, prompting Google to consolidate its efforts into the Antigravity platform, announced earlier this year. The new Antigravity CLI aims to unify the development experience across desktop and terminal, supporting advanced agent orchestration and asynchronous workflows.
