Our verdict: Antigravity is Google's take on the agent-first editor: agents work across the editor, terminal and a browser and report back with plans, screenshots and walkthroughs you can comment on. The free plan includes unlimited Tab completions and a weekly agent quota, which is generous for trying it. The newest models need a paid Google AI plan, and only personal Google accounts in supported countries can sign in.
About Google Antigravity IDE
Google Antigravity IDE is the standalone editor in Google's Antigravity family, next to the Antigravity App, CLI, SDK and extensions for other editors. Its Editor view offers Tab completion, natural-language commands and an agent side panel. The Agent Manager runs agents that operate the editor, terminal and browser, and they produce Artifacts such as implementation plans, walkthroughs and screenshots that you review and comment on.
The individual plan costs $0 and includes access to several agent models, unlimited Tab completions, unlimited Command requests and basic weekly rate limits. Google AI Pro and Ultra subscriptions raise the limits and unlock models such as Gemini 4 Argon. You must sign in with a personal Google account in an approved country, be 18 or older, and your code is processed by Google's cloud models; data collection can be switched off in Settings.
