Google Antigravity

About

Google Antigravity is Google's agentic development platform. Google's site describes it as "our agentic development platform, allowing anyone to build in the agent-first era". It comes as a desktop app that acts as a command center for several local agents, a terminal CLI called agy, IDE extensions and a Python SDK. As of October 2026 there is a free plan for individuals, higher limits with Google AI Pro and Google AI Ultra, and business plans through Google Cloud from $30 a month per seat. Google's other tools now point to it: Firebase Studio users are told they can migrate to it, and Gemini CLI's repository says free individual access and Google AI Pro and Ultra moved to Antigravity CLI on 18 June 2026. It belongs with the agent tools on our best AI coding assistant page and in our Gemini vibe coding collection. What Antigravity does • Antigravity App: a desktop command center for managing multiple local agents in parallel. The getting-started guide lists app version 2.5 or later. • Antigravity CLI: a terminal-first client, invoked as agy (version 1.2 or later), for working with Antigravity agents. • IDE and extensions: a standalone Antigravity IDE, plus extensions for VS Code, Visual Studio, JetBrains, Zed, Xcode and Eclipse. • Antigravity SDK: a Python SDK (google-antigravity) for prototyping custom agents. It needs Python 3.10 or later. • Plugin Marketplace: announced on Antigravity's blog on 29 October 2026. Platforms and sign-in • Desktop: the guide lists macOS 12 or later (Apple Silicon or Intel), Windows 10 (64-bit) or 11, and Linux with glibc 2.28 or later. Googlebook devices come with the app preinstalled. • Sign-in: the docs list four auth types: oauth-personal, oauth-business (Gemini Enterprise, Preview), gemini-api-key and agent-platform (Preview). Pricing and limits (as of October 2026) • For Individuals: $0 a month. Labelled generally available. Includes access to a variety of agent models, unlimited Tab completions, unlimited Command requests and basic weekly rate limits. Google's plans documentation describes the baseline quota for users without a Pro or Ultra plan as "a meaningful quota, refreshed weekly". • Google AI Pro: everything in Individuals plus more rate limits and a flexible AI credit pool. The plans documentation says the quota refreshes every five hours until the weekly limit is reached. The Antigravity pricing page shows no price. • Google AI Ultra: even more rate limits and the highest weekly limits. The plans documentation says it includes access to third-party models. The Antigravity pricing page shows no price. • Business plan via Google Cloud: eligible Gemini Enterprise customers can choose Standard or Plus seats from $30 per seat a month, or a pay-as-you-go plan with no seat fee. It lists API access with consumption-based pricing, spend caps and centralized admin controls. • AI credits: Pro and Ultra users can buy credits or use promotional credits beyond the baseline, consumed at Gemini Enterprise consumption pricing. An AI Credit Overages setting chooses Never or Always. Google says limits are mainly set by available capacity, complex tasks use more quota than simple ones, and limits may change. Recent news (official blog) • 29 October 2026: Plugin Marketplace in Antigravity. • 26 October 2026: a research post on how Gemini 4 Argon upleveled agents on Antigravity, covering trillion-edge graphs and custom TPU kernels. • 13 October 2026: Gemini 4 Argon in Google Antigravity. Google's Gemini CLI repository says Gemini CLI has not been optimised for Gemini 4 Argon and points users to Antigravity. • 21 August 2026: "Antigravity anywhere with Remote Control". Who it suits • Developers who want to supervise several agents at once from one desktop app. • Terminal users who prefer a CLI agent. • Former Firebase Studio or Gemini CLI users looking for Google's current replacement. • People who want a free tier to try an agent-first workflow. Limitations to know • The free plan has basic weekly rate limits only. • Google AI Pro and Ultra prices are not shown on the Antigravity pricing page. • Limits depend on capacity and can change, per Google. • Third-party model access is described for Ultra in the plans documentation.
