The Bottom Line: Google is transitioning Gemini CLI to the new Antigravity CLI to better support modern multi-agent workflows, preserving core features while improving performance, with migration complete by June 2026.
Google has announced that the popular Gemini CLI will transition to the new Antigravity CLI. The migration is intended to meet the demands of modern multi-agent workflows and provide a unified platform for future development.
Since the launch of Gemini CLI last year, the tool has gained significant traction in the developer community – over 100,000 GitHub stars, 6,000 merged pull requests, and hundreds of contributors demonstrate its success. However, user feedback revealed that requirements have grown substantially.
The original vision of Gemini CLI – bringing the power of Gemini directly to the terminal – proved that terminals are excellent interfaces for agent-driven tasks. Today, however, developers need something more complex: multiple agents communicating with each other to solve complex problems and divide tasks.
To best meet these new demands, Google is consolidating its efforts. The focus shifts to Google Antigravity – a new agent-first development platform with a powerful server-side framework and an entirely new terminal experience: Antigravity CLI.
The core features of Gemini CLI – Agent Skills, Hooks, Subagents, and Extensions (now as Antigravity Plugins) – are being preserved. Antigravity CLI offers significant additional improvements: built in Go, the application is faster and more responsive, enables asynchronous workflows for complex background tasks, and uses a unified architecture that remains synchronized with Antigravity 2.0.
Antigravity CLI is now available for all users. However, a sunset date applies: On June 18, 2026, Gemini CLI and the Gemini Code Assist IDE extensions for Google AI Pro and Ultra subscribers, as well as free users, will be discontinued. The same date applies for GitHub users – no new installations will be permitted after that point. Enterprise customers will receive separate guidance.
