About

Google Antigravity is Google's agent-first development environment, now generally available. It is a full IDE built around autonomous agents rather than autocomplete, and it is the most aggressively priced of the big-vendor options: the individual plan is $0 and includes unlimited tab completions and unlimited command requests, plus access to a wide model roster spanning Gemini 3.x Flash and Pro and Claude Sonnet and Opus, subject to basic weekly rate limits. Above that sit the Google AI Pro and AI Ultra subscriptions, which unlock looser rate limits and a flexible AI credit pool. Google has never published those prices on the Antigravity pricing page itself — the page pushes you to an upgrade flow — though Google AI Pro is widely tracked at $20/month and AI Ultra at $100/month. What matters more for budgeting is the March 2026 change: Antigravity introduced a credit system ($25 buys 2,500 credits) and sharply cut how much agent usage the free tier includes, with third-party trackers measuring a roughly 92% reduction. In practice the free tier is now an evaluation tier, not a production one. For organisations there is a newer Organization plan delivered through Google Cloud: Antigravity 2.0 and a CLI, billed as consumption-based API pricing against the Gemini Enterprise Agent Platform, and included in some Gemini Enterprise app subscriptions. It arrives with Google Cloud terms of service, Cloud project integration and centralised admin. Antigravity is strongest if you are already in Google's ecosystem or want a genuinely free way to try agentic coding; the trade-off is that real limits live in Google's docs rather than on the pricing page, and free-tier allowances have moved twice in a year.

Antigravity's free plan is the cheapest way into agentic coding — unlimited completions plus a limited pool of agent work — but it is an evaluation tier after the March 2026 cuts. If you already subscribe to Google AI Pro or Ultra, use those included limits, and prefer the organisation plan only when your existing Google Cloud spend can absorb consumption-based API pricing.
