About
Announced in November 2025 alongside Gemini 3, Google Antigravity is an agentic development platform built as a fork of Visual Studio Code. It introduces two core views: an Editor view resembling a traditional IDE with an AI agent sidebar, and a Manager view — a control center for orchestrating multiple agents working in parallel across workspaces. Agents produce verifiable Artifacts (task lists, implementation plans, screenshots, browser recordings) rather than raw tool calls, providing full transparency into autonomous actions. Antigravity supports Gemini 3.1 Pro, Claude Sonnet 4.5, and OpenAI models, with generous rate limits during the public preview phase. It targets developers who want to delegate entire workflows — not just code completion — to AI agents.
Key Features
- Agent Manager for orchestrating multiple parallel AI agents
- Artifact-based transparency (task lists, plans, screenshots, browser recordings)
