Antigravity CLI replaces Gemini CLI for individual accounts

Google announced on May 19, 2026 that it is moving its terminal agent from Gemini CLI to Antigravity CLI. On June 18, 2026, Gemini CLI and the Gemini Code Assist IDE extensions stopped serving requests for Google AI Pro and Ultra accounts and for free use. The announcement says there "won't be 1:1 feature parity right out of the gate".

Who keeps Gemini CLI

Customers on Gemini Code Assist Standard or Enterprise licenses, and organizations using Gemini Code Assist for GitHub through Google Cloud, keep access. Gemini CLI also stays reachable with paid Gemini and Gemini Enterprise Agent Platform API keys. The Gemini CLI README now describes it as maintained for enterprise Code Assist workflows, and says it is not tuned for the Gemini 4 series.

What Antigravity CLI is

Antigravity CLI is built in Go, runs as agy, and uses the same agent harness as the Antigravity 2.0 desktop app. Install it on macOS or Linux with:

curl -fsSL https://antigravity.google/cli/install.sh | bash

Skills, hooks, subagents and MCP carry over. Gemini CLI extensions become Antigravity plugins:

agy plugin import gemini

Workspace skills move from .gemini/skills/ to .agents/skills/ by hand, and MCP servers move out of ~/.gemini/settings.json into ~/.gemini/config/mcp_config.json. The migration guide has the full mapping.

What changed here

The Gemini CLI sheet is retired. The Antigravity CLI sheet replaces it, and /gemini-cli now redirects there.
