Google Antigravity

Google Antigravity is presented as an agentic development platform for building in what it calls the agent-first era. Its components include Antigravity 2.0, a command center for managing multiple local agents in parallel, and Antigravity CLI, a terminal-first surface for running autonomous coding agents and background subagents. The page also describes an Antigravity SDK for prototyping custom agents with Python scripts and an Antigravity IDE with an agent manager and artifacts. The text states the platform is available at no charge.
