What is Google Antigravity CLI?

Google Antigravity CLI is a lightweight terminal-based interface for invoking, monitoring, and interacting with Antigravity agents. It brings multi-step reasoning, multi-file editing, tool calling, and persistent history directly to the command line. Optimised for SSH sessions and keyboard-first workflows, it complements Google Antigravity 2.0 as a fast, no-frills alternative that shares the same agent harness and settings.

Who it's for

• Terminal purists who prefer a true CLI experience over graphical interfaces and want to stay entirely in the command line.
• SSH power users who need a lightweight agent interface that works efficiently over remote sessions without GUI overhead.
• Keyboard-first developers who value speed, low overhead, and persistent conversation history in their daily coding workflow.

Key features

Shared agent harness with Antigravity 2.0

The Antigravity CLI uses the same agent harness as Antigravity 2.0, meaning future improvements to core agents automatically apply to both surfaces. Common settings are also shared, so permissions configured in one product carry over to the other.

Conversation import from CLI to Antigravity 2.0

While conversations are not shared by default, you can pull up CLI-started conversations from Antigravity 2.0 using the @conversation dropdown. This bridges the gap between the two interfaces without losing context.

Optimised for speed and low overhead

The Antigravity CLI is deliberately stripped of GUI features to remain fast and lightweight. It inherits core harness and agentic improvements from the broader Antigravity ecosystem while prioritising minimal resource usage.

Migration path from Gemini CLI

For existing Gemini CLI users, Google provides guides to transfer skills, MCP servers, and customisations to the Antigravity CLI. This unification brings the best insights from Gemini into a focused CLI and agent experience.

What stands out

"The Antigravity CLI will be optimised for speed and low overhead, while Antigravity 2.0 is optimised for comprehensiveness in its feature set."

This clear design philosophy means you get a purpose-built tool that doesn't try to be everything. The CLI focuses on what terminals do best—fast, keyboard-driven interaction—while leaving visual complexity to Antigravity 2.0. The shared harness ensures you never miss out on core agent improvements, and the ability to import conversations between surfaces gives you flexibility without duplication.

Worth checking out if…

You live in the terminal, work over SSH, or want a no-compromise CLI agent that stays out of your way. If you already use Gemini CLI, the migration guides make switching straightforward. For anyone who values speed over visual polish, the Antigravity CLI delivers a focused, keyboard-first experience that complements the broader Antigravity ecosystem.
