Gemini CLI Is Dead. Meet Antigravity CLI

If you use Gemini CLI, you have a hard deadline: June 18, 2026. After that, it stops serving requests for free users, Google AI Pro, and Google AI Ultra subscribers.

Google announced the transition at I/O 2026 yesterday. The replacement is Antigravity CLI — part of the broader Antigravity 2.0 platform Google is pushing as its agent-first dev environment.

Why Google Is Making the Switch

Google's reasoning is straightforward: Gemini CLI proved the terminal could handle agentic tasks, but developer workflows have shifted toward multi-agent systems that split up work and share a unified backend.

Antigravity CLI is Google's answer to that shift.

What's Actually Different

Antigravity CLI is built in Go — it's noticeably faster, supports asynchronous background workflows for complex tasks, and shares a unified architecture with the Antigravity 2.0 desktop app.

It keeps the key Gemini CLI features you probably relied on — Agent Skills, Hooks, Subagents, and Extensions — now reimplemented as Antigravity plugins.

The big addition is async workflows. You can run large-scale refactors or research tasks in the background without locking up your terminal session. That's genuinely useful if you've ever sat watching Gemini CLI grind through a long task.

The Antigravity Platform Is Bigger Than Just a CLI

Worth knowing: the Antigravity brand now covers four products — Antigravity 2.0 (the new desktop app with multi-agent orchestration), Antigravity CLI, the Antigravity SDK, and Antigravity IDE (the original VS Code-style app from November 2025). All sharing the same agent harness under the hood.

Who's Affected and When

Starting June 18, 2026, Gemini CLI and Gemini Code Assist IDE extensions stop serving requests for free users and paid Google AI Pro/Ultra users. Enterprise and Standard license holders are not affected — their access remains unchanged.

The Gemini CLI repo isn't going anywhere either. It stays on GitHub as an Apache 2.0 open source project, with ongoing bug fixes and model updates for enterprise customers.

What You Should Do Now

Antigravity CLI is available to download today. Google has a migration guide up, with video walkthroughs coming in the next few weeks.

If you've got CI scripts or project workflows tied to Gemini CLI, don't wait until June 17. The sooner you test Antigravity CLI against your actual workload, the more time you have to work around anything that breaks.
