TL;DR
Google is replacing Gemini CLI with Antigravity CLI to support complex multi-agent workflows, keeping critical features but requiring users to transition by June 18, 2026.
Key points
- 1
Why the shift happened: Gemini CLI was designed for simple terminal interactions but couldn't scale as users needed to coordinate multiple AI agents for complex tasks. Over 100,000 GitHub stars and 6,000 pull requests showed strong community adoption, but feedback revealed that users required a unified backend to handle workflows like splitting tasks across agents. This shift addresses the growing need for multi-agent coordination in development, where tools must share a single infrastructure to avoid fragmentation. For example, a developer using Gemini CLI to build a cloud infrastructure project now needs Antigravity CLI to manage multiple agents simultaneously without terminal freezes.

What's kept from Gemini CLI: Antigravity CLI preserves key Gemini features like Agent Skills, Hooks, Subagents, and Extensions (now plugins) to ensure continuity. Users can still get quick answers, scaffold coding projects, or provision cloud infrastructure through the new CLI. The transition focuses on practical improvements: Antigravity CLI runs in Go for faster execution, supports asynchronous workflows for large-scale tasks, and shares the same agent harness as Antigravity 2.0, the desktop app. This means if you used Gemini CLI to generate a project structure, you can now do it with Antigravity CLI without losing functionality—just with better performance and seamless integration with future updates.

Timeline and access changes: Antigravity CLI is available immediately, but Gemini CLI and related extensions will stop serving requests for Google AI Pro and Ultra on June 18, 2026. Enterprise customers using Gemini Code Assist via Google Cloud licenses remain unaffected and can continue using Gemini CLI through paid API keys. For GitHub organizations, new installations of Gemini Code Assist will stop on June 18, 2026. If you're using the free version of Gemini Code Assist for individuals, you'll need to switch to Antigravity CLI by that date to avoid service interruptions. This timeline ensures a smooth transition while prioritizing enterprise needs and preventing disruptions for most users.
