Google Antigravity: Pricing, Features, and Plans (2026)

What is Google Antigravity?

Google Antigravity is Google's agentic development platform, built for working with AI agents rather than only alongside autocomplete. It includes an agent-first IDE with an agent manager and codebase-aware context, Antigravity 2.0 for running several local agents in parallel across projects, a terminal CLI that can run background subagents, and a Python SDK for prototyping custom agents. It runs on macOS, Windows, and Linux.

Every plan includes Gemini models, and paid plans add Claude Sonnet 5.5 and Claude Opus 5.5. The free individual plan has weekly rate limits, while Google AI Pro and Ultra raise those limits and add a flexible AI credit pool. Organizations can buy seats through Google Cloud or pay as they go, with spend caps across both. If you're comparing it with other coding agents, see these Google Antigravity alternatives.
