What it does

Google Antigravity is an agentic development platform from Google. It includes an app for managing multiple local agents in parallel, a terminal-first CLI, an IDE with an agent manager and artifacts, and a Python SDK for prototyping custom agents. It runs on macOS, Windows, Linux, and Googlebook.

Google Antigravity is a platform for developers who want to work with coding agents across several surfaces. The app manages multiple local agents in parallel and groups conversations into Projects. The CLI runs autonomous coding agents and shell commands from the terminal. The IDE adds an agent manager, artifacts, and codebase understanding. The SDK lets you prototype custom agents with Python scripts. The individual plan costs $0 per month and includes access to a variety of agent models, unlimited Tab completions, unlimited Command requests, and basic weekly rate limits. Paid Google AI Pro and Ultra plans add more rate limits and a flexible AI credit pool. Organizations can use a Business plan through Google Cloud, and there is API access with consumption-based pricing. The homepage does not state an open source license, and it does not say whether an account is required to use the product.
