Google Antigravity review

Google Antigravity replaced Gemini Code Assist for consumer accounts, whose IDE extensions stopped serving individual and Google AI subscription tiers on June 18, 2026. It is now a family of products: an app for running several local agents in parallel with projects and scheduled messages, a CLI for terminal work and background subagents, a full IDE with an agent manager, and an SDK for prototyping custom agents. The free individual plan includes access to a variety of agent models, unlimited Tab completions and unlimited command requests, with basic weekly rate limits. Google AI Pro at $19.99 a month adds higher limits and a flexible AI credit pool, and Ultra, from $99.99, raises them further. Organizations reach it through Google Cloud, with Gemini Enterprise seats from $30 a month or pay-as-you-go API pricing. It trails the top three on agent features and on how clearly limits are published.
