## Project history and usage

Antigravity CLI is Google's terminal interface for Antigravity agents. Its official README describes a command-line tool that understands a codebase, makes edits with permission, executes commands, and brings Antigravity 2.0 capabilities into a keyboard-driven terminal workflow.

### Project history

Google announced Antigravity CLI on 2026-05-19 as part of its transition from Gemini CLI to a unified Antigravity development platform. The announcement positioned the CLI as the new terminal experience for Antigravity, backed by the same agent harness as Antigravity 2.0.

The official GitHub repository documents installation scripts for macOS, Linux, and Windows, browser or keyring-based authentication, SSH-aware login flow, and the `agy` executable.

### Adoption history

Google framed Antigravity CLI adoption around migration from Gemini CLI, saying Gemini CLI had reached millions of users, more than 100,000 GitHub stars, 6,000 merged pull requests, and hundreds of contributors before the transition.

Homebrew distributes Antigravity CLI as a cask. The official GitHub release feed showed 1.1.1 published on 2026-07-10, matching the supplied Homebrew cask version metadata for this batch.

### How it is used

The official workflow is to install the CLI, run `agy`, authenticate with Google Sign-In or an existing system keyring session, and let the agent inspect, edit, and run commands inside a codebase with user approval.

### Why package nerds care

Antigravity CLI is notable because it packages an AI coding-agent environment as a normal terminal tool while still depending on cloud authentication, release archives, shared settings, permissions, plugins, persistent history, and GUI handoff.

### Timeline

- 2026-05-19: Google announced Antigravity CLI and the Gemini CLI consumer transition.
- 2026-06-18: Google scheduled Gemini CLI and Gemini Code Assist IDE request shutdown for consumer and free individual use.
- 2026-07-10: GitHub published Antigravity CLI 1.1.1.
