Google Antigravity

What it is for

Google Antigravity is Google’s agent IDE, CLI, and SDK: you pick a surface (App, CLI, editor extensions, or SDK), install it, and the agent works a project with Tab and Command. Use it when the job is Gemini-backed agents in a Google account.

For Individuals is $0/month. Paid quota rides Google AI Pro and Ultra. The cover is the official Get started docs — surface cards plus the App installer.

What makes it unique: one product with four public surfaces, and Individual access starts at $0 with weekly agent limits.

Key features

• Four surfaces — Antigravity App, CLI, IDE extensions, SDK (cover).
• Tab — inline completions while you type in the editor (Supercomplete, Tab-to-Jump, Tab-to-Import).
• Command — send a repo task from the command bar.
• Artifacts — review Markdown plans, diffs, diagrams, and browser recordings; leave inline feedback before the agent edits files (docs).
• /browser — hand a Chrome task to the built-in browser subagent: navigate, inspect console/network, capture screenshots and WebM recordings (docs).
• Gemini models — Flash / Pro family the agent uses on a project.

Who it's for

Best fit: developers on a Google account who want an agent IDE/CLI and will watch the weekly quota.
