Google Antigravity transforms coding by letting developers manage multiple AI agents like a team of virtual employees, handling planning, building, testing, and marketing autonomously. Released alongside Gemini 3 Pro, this free IDE fork of VS Code emphasizes agent-first workflows over traditional chat interfaces.
Core Workflow Breakdown
The video demonstrates starting with a workspace for a stock investment app using Next.js and Tailwind CSS. Users provide an initial prompt for a plan—entering stock tickers to display price charts and news—while attaching UI screenshots from tools like V0 for visual guidance. In planning mode, the agent creates artifacts like detailed implementation documents, which users review without code execution yet.
Agents then build V1 automatically, integrating browser testing via a Chrome extension for end-to-end validation, including clicks and screenshots. Key power tip: Annotate screenshots during tests to trigger fixes, such as adding crypto sections.
Multi-Agent Management
Access the Agent Manager to spin up specialized agents simultaneously—a product manager for roadmaps, a marketing agent for blog posts and tweets, and a developer for portfolio tracking with share inputs and daily value changes. Workspaces handle main projects, while playgrounds enable quick experiments like a 3D shooter game using Three.js.
The inbox serves as a central hub for agent updates, approvals, and artifacts, shifting users from hands-on coding to oversight.
Why It Stands Out
Antigravity’s artifacts—plans, walkthroughs, and recordings—provide transparency beyond logs in tools like Cursor. Free with generous Gemini 3 limits, it supports Claude Sonnet 4.5 and runs on Windows, macOS, and Linux. Download from antigravity google to replicate the demo and boost productivity.
