Antigravity CLI

Antigravity CLI is Google's terminal-first surface for interacting with the Antigravity agentic development platform, announced at Google I/O. It is part of the broader Google Antigravity ecosystem, which also includes a desktop app (Antigravity 2.0), an SDK, and a full IDE. The CLI is designed for developers who prefer keyboard-driven workflows and want direct, low-overhead access to Antigravity's agent capabilities.

What It Is

Antigravity CLI is a command-line interface that lets developers run autonomous coding agents, execute shell commands directly, and manage background subagents — all from the terminal. It is described on the Antigravity product page as "the lightweight, fast, terminal-first surface to work with Antigravity agents." The CLI is one of four surfaces in the Antigravity platform, positioned as the fastest and most minimal entry point for developers already comfortable in the terminal.

Where It Fits in the Antigravity Platform

The Antigravity platform consists of four distinct surfaces:

• Antigravity CLI — terminal-first, lightweight, keyboard-driven agent access
• Antigravity 2.0 — a desktop command center for managing multiple local agents in parallel, with Projects, multi-workspace support, and scheduled messages
• Antigravity SDK — a Python-based prototyping layer for building custom agents on top of the Antigravity harness
• Antigravity IDE — a fully-featured agentic IDE with an agent manager, artifacts, and deep codebase understanding

The CLI is the entry point for developers who want to stay in the terminal and avoid switching to a GUI.

Core Capabilities

According to the Antigravity product page, the CLI supports:

• Running autonomous coding agents directly from the terminal
• Executing shell commands through the agent interface
• Managing background subagents in parallel
• Access to the same model lineup available across the platform, including Gemini 3.5 Flash, Gemini 3.1 Pro, Gemini 3 Flash, Claude Sonnet & Opus 4.6, and gpt-oss-120b (on the free Individual plan)
• Unlimited tab completions and unlimited command requests (on the free Individual plan)

Target Audience

The Antigravity homepage positions the platform for a range of developer profiles: full-stack developers building production-ready applications, enterprise developers working in large codebases, and frontend developers automating repetitive UX tasks. The CLI surface specifically targets developers who prefer terminal workflows and want a fast, minimal interface without the overhead of a full IDE or desktop app.

Launch and Current Status

Antigravity CLI was announced at Google I/O and is currently generally available. The pricing page lists it as part of the "Generally Available" tier. The CLI is available for Linux at launch, as indicated by the homepage's "Download for Linux" call to action. The Organization plan, available via Google Cloud, also includes access to Antigravity CLI alongside Antigravity 2.0, under Google Cloud Terms of Service with consumption-based API pricing through the Gemini Enterprise Platform.
