On May 19, Google announced that it would officially discontinue the Gemini CLI and Gemini Code Assist IDE extensions for Google AI Pro, Ultra, and free users on June 18. On the same day, Gemini Code Assist for GitHub also stopped accepting new installations within GitHub organizations; existing requests are set to stop being processed within the coming weeks. Meanwhile, Antigravity CLI was officially released today, allowing developers to begin migrating right away. Since its launch last year, Gemini CLI has attracted millions of users, garnered over 100,000 GitHub Stars, and seen more than 6,000 merged pull requests. However, as user workflows increasingly shift toward multi-Agent collaboration, the existing architecture proved inadequate; hence Google decided to consolidate all terminal-based tools under its Google Antigravity agent-first development platform.
Retaining all core functionalities of Gemini CLI — including Agent Skills, Hooks, sub-Agents, and Extensions (now renamed Antigravity Plugins) — Antigravity CLI introduces three major enhancements: it’s been rewritten in Go, resulting in faster response times; it supports asynchronous workflows, enabling multiple Agents to operate concurrently in the background for large-scale refactoring or concurrent research tasks without blocking terminal sessions; and it shares the same Agent execution layer as the Antigravity 2.0 desktop app, ensuring any improvements made to the core Agent automatically propagate to the terminal environment. For enterprise clients utilizing Gemini Code Assist Standard or Enterprise licenses, or those accessing services via paid API keys, Gemini CLI remains fully accessible despite this transition. Technical migration guides have already been published, with video tutorials scheduled to follow in the upcoming weeks.
