Gemini CLI is Shutting Down in June 2026! Complete Transition to Google’s Next-Gen Agent Framework ‘Antigravity’ Incoming, Folks!

📰 News Overview

• End of Gemini CLI: The services for Gemini CLI and Gemini Code Assist will end on June 18, 2026, for individual and free users, as well as Pro and Ultra subscribers.
• Emergence of the Successor Tool: Google has unveiled “Google Antigravity,” a cutting-edge agent-first development platform, making the “Antigravity CLI” publicly available starting today.
• Multi-Agent Capability: Redesigned to meet evolving user needs post-2025, this tool allows multiple agents to collaborate on complex tasks in parallel.

💡 Key Highlights

• Lightning-Fast Built with Go: Antigravity CLI is developed in Go, significantly enhancing responsiveness compared to traditional CLIs.
• Asynchronous Workflow Implementation: Users can run extensive refactoring or research on multiple topics in parallel with various agents without locking the terminal.
• Unified Architecture: Shares a common “Agent Harness” with Antigravity 2.0 (desktop app), ensuring core agent improvements are instantly reflected across all environments.

🦈 Shark’s Eye (Curator’s Perspective)

This isn’t just a name change, folks! The concept of “one AI interacting via CLI” is getting a complete makeover as this tool evolves into a “command center for multiple agents.” Notably, the asynchronous workflow implementation is a game-changer! No longer will your work halt while waiting for AI responses; now you can delegate heavy tasks to subagents while you tackle other projects. It’s like turning your terminal into a control room for a factory! Plus, existing Agent Skills and Hooks will transition as “Antigravity plugins,” so your automation assets won’t go to waste—now that’s a clever twist!

🚀 What’s Next?

In the realm of individual developers, the “one vs. multiple AI agents” development style will become the norm. By late 2026, we can expect a shift towards a style where agents will be writing code while you play the role of the supervisor, rather than coding directly in the terminal.

💬 A Word from Haru Same

Finally shedding the Gemini name for “Antigravity”! It’s like unleashing development speed from the shackles of gravity! I’m diving right in and swimming around in this new world! 🦈🔥

📚 Term Glossary

• Antigravity CLI: Google’s new agent development platform for managing multiple AI agents from the terminal.

• Asynchronous Workflow: A mechanism allowing actions to proceed without waiting for task completion. Execute other commands while the AI handles heavy processing in the background.

• Agent Harness: A common foundation for agents to operate. It enables the sharing of agent capabilities between server-side and client-side environments.
