Google Antigravity

Google Antigravity is an agentic development platform from Google that lets developers plan, write and test software by directing AI agents instead of typing every line. It goes beyond a single editor: there is a desktop app for managing several agents at once, a full IDE, a command line tool and an SDK. For individual developers it is available at no charge, which makes it one of the easiest ways to try an agent-first workflow on your own projects.

What is Google Antigravity used for?

Antigravity is used for building and maintaining software with agents that can read a codebase, propose changes, run commands and check their own work. Google pitches it at everyone from enterprise engineers to hobbyists.

• Running multiple local agents in parallel from the Antigravity App and grouping their conversations into projects across workspaces
• Editing code in the Antigravity IDE with an agent manager, artifacts and codebase context
• Using browser-in-the-loop agents to click through and test frontend changes
• Running autonomous agents, shell commands and background subagents from the Antigravity CLI
• Prototyping custom agents and running evaluations with the Python-based Antigravity SDK

Who Google Antigravity is best for

It fits individual developers and students who want a capable agentic IDE without paying, teams already on Google Cloud or Gemini Enterprise, and frontend developers who like agents that can verify UI changes in a browser. Former Gemini CLI users on the unpaid tier are effectively pointed here, since the Gemini CLI site says it was replaced by the Antigravity CLI for that tier in June 2026. Developers who want to pick from many third-party models, or who need a tool that runs fully offline, should look elsewhere.

Google Antigravity pricing

As of October 2026, the pricing page lists an Individuals tier at $0 per month with access to a range of agent models, unlimited Tab completions and Command requests, and basic weekly rate limits. Google AI Pro and Google AI Ultra subscribers get progressively higher rate limits plus a flexible AI credit pool, though the page does not print those subscription prices. For organizations, Antigravity is sold through Google Cloud: Gemini Enterprise Standard and Plus seats start at $30 per user per month, a pay-as-you-go option has no seat fee, and API use is billed by consumption. Business plans add Google Cloud terms, spend caps and central admin controls.

Limitations to keep in mind

• The free tier's weekly limits are not published as numbers, so heavy users may hit them without warning
• Model choice centers on Google's own Gemini models
• Enterprise use requires going through Google Cloud billing and admin setup

Google Antigravity vs alternatives

Cursor is the most popular AI code editor and offers broader model choice, so it is the safer pick if you want to switch between providers. Devin Desktop, formerly Windsurf, is a close match for developers who want an agentic editor from a company focused only on coding tools. Kiro, from AWS, is better if you like spec-driven development where requirements and design docs come first. GitHub Copilot makes sense for teams that want AI inside their existing editor and GitHub workflow. Google Antigravity wins on price for individuals and on running several agents side by side from one desktop app.

Tips for getting started with Google Antigravity

Install the desktop build for your operating system and open an existing project rather than starting empty, so the agent has real code to learn from. Start with one agent and one clearly scoped task, then try running two in parallel on separate branches. For frontend work, ask the agent to verify changes in the browser before you review the diff.

Google Antigravity FAQ

Yes, Google Antigravity is free for individual developers with basic weekly rate limits, as of October 2026. Google AI Pro and Ultra subscriptions raise those limits.

What is Google Antigravity used for?

Google Antigravity is used to build software with AI agents that plan, write, run and test code, through a desktop agent manager, an IDE, a CLI and a Python SDK.

Does Google Antigravity replace Gemini CLI?

For unpaid and Google One users, yes. The Gemini CLI site states it was replaced by the Antigravity CLI for those users on June 18, 2026.

Google Antigravity vs Cursor: which is better?

Google Antigravity is the better value for individuals because it is free and runs parallel agents, while Cursor offers more model choice and a more mature editor ecosystem.
