Google Retires Gemini CLI, Launches Antigravity CLI as Agent-First Successor
Key Takeaways
- ▸Gemini CLI will stop working on June 18, 2026, for free and paid consumer users, with Antigravity CLI as the replacement
- ▸Antigravity CLI is agent-first and supports multi-agent orchestration for complex workflows running asynchronously
- ▸Built in Go, Antigravity CLI offers improved performance and shares a unified architecture with Antigravity 2.0 desktop app
Summary
Google is discontinuing Gemini CLI and replacing it with Antigravity CLI, a new agent-first development platform launching today. The company announced the transition following feedback from millions of users, noting that modern AI workflows have evolved beyond single-agent terminal tools to require multi-agent systems that can coordinate and solve complex problems together.
Antigravity CLI is built on a unified architecture shared with Antigravity 2.0 desktop application, ensuring that improvements to core agents automatically apply across all interfaces. The platform is written in Go for enhanced performance, supports asynchronous workflows for running multiple agents in the background, and preserves critical Gemini CLI features including Agent Skills, Hooks, Subagents, and Extensions (now as Antigravity plugins).
The deprecation timeline differs by user type: Gemini CLI and related IDE extensions will stop serving requests on June 18, 2026, for free users, Google AI Pro and Ultra subscribers, and Gemini Code Assist for individuals. Enterprise customers with Gemini Code Assist Standard or Enterprise licenses can continue using Gemini CLI indefinitely on paid plans, with ongoing access to the latest Gemini models and updates.
Google is offering documentation, video walkthroughs, and community forum support to help users transition to Antigravity CLI. The company emphasized that while full feature parity isn't guaranteed at launch, the new platform addresses the most critical use cases from Gemini CLI, including quick terminal lookups, project scaffolding, and cloud infrastructure provisioning.
- Enterprise customers on paid Gemini plans can continue using Gemini CLI indefinitely
- Core Gemini CLI features (Agent Skills, Hooks, Subagents, Extensions) are preserved in Antigravity CLI
Editorial Opinion
Google's shift from single-agent Gemini CLI to multi-agent Antigravity CLI reflects the industry's maturation toward coordinated AI systems and agent orchestration. By unifying the terminal and desktop experiences under a shared harness, Google is positioning Antigravity as a comprehensive platform for AI-driven development workflows. However, the June deadline for sunsetting consumer access to Gemini CLI creates significant migration pressure for millions of free and Pro users.
