About Google Antigravity

Overview

Google Antigravity is Google's agentic development platform. It spans a desktop app that manages multiple local agents in parallel across projects, a terminal-first CLI for autonomous coding agents, a full agentic IDE with an agent manager and artifacts, and a Python SDK for building custom agents. It runs on macOS, Windows and Linux, supports browser-in-the-loop agents for frontend work, and offers Gemini 4 Argon to Google AI Pro and Ultra subscribers.

Best for

Developers who want to run several coding agents in parallel and review their work as artifacts
Terminal-first users who want an autonomous coding agent through the CLI
Teams building custom agents on the same harness through the Python SDK

Not ideal for

Teams that need documented permission and approval controls before delegating repository access
Heavy daily users who cannot confirm the free-tier limits or plan prices
Anyone who wants to pin a specific third-party model rather than Google's own

What reviewers say

Reviews describe Antigravity as an agent-first alternative to editor-centric assistants, praising the parallel agent management and the shared harness across surfaces. The most repeated concerns are free-tier rate limits and how plan prices differ between reports.
