Google unveils Antigravity, a new development environment that uses AI agents to autonomously handle complex coding tasks. Built as a VS Code fork and powered by Gemini 3 Pro, it offers multi-agent orchestration and browser integration.

Revolutionary Agent-First Development Platform

Google has officially launched Antigravity, a groundbreaking development environment that represents a significant shift toward "agent-first" software development. Announced alongside the debut of Gemini 3 Pro, Antigravity is designed to transform how developers approach coding by enabling AI agents to autonomously handle complex, end-to-end software tasks

The platform allows multiple agents to work simultaneously with direct access to the editor, terminal, and browser, fundamentally changing the developer's role from hands-on coder to high-level architect. Rather than simply suggesting code completions, Antigravity acts as a digital team leader, orchestrating intelligent agents to manage entire software features based on simple instructions

Built on Familiar Foundation

While Google didn't explicitly mention it in official announcements, Antigravity is built as a fork of Microsoft's open-source Visual Studio Code. This strategic decision provides immediate familiarity for developers already accustomed to VS Code's interface and functionality

The platform offers two distinct usage modes. The default Editor view provides a traditional Integrated Development Environment experience similar to competitors like Cursor and GitHub Copilot, with an AI agent positioned in a side panel. The innovative Manager view, however, is specifically designed for controlling multiple agents simultaneously, allowing them to work autonomously across different workspaces in parallel

Advanced Verification and Feedback Systems

One of Antigravity's most distinctive features is its "Artifacts" system, which addresses a critical challenge in AI-assisted development: verification of work completed. As agents complete tasks, they generate comprehensive documentation including task lists, plans, screenshots, and browser recordings that verify both completed work and future plans. Google emphasizes that these Artifacts are "easier for users to verify" than traditional lists of model actions and tool calls

The platform introduces sophisticated feedback mechanisms, allowing developers to leave comments directly on specific Artifacts. This enables agents to incorporate feedback without interrupting their current workflow, addressing a common frustration with existing AI coding tools

Browser Integration and Real-Time Testing

Antigravity includes advanced browser integration through a Google Chrome extension that enables AI agents to run code within actual Chrome instances, test applications, observe behavior, and take corrective action. This capability allows the platform to interact deeply with web applications in real-time, potentially leading to significant productivity improvements for web development projects

The system can capture its own screenshots and screen recordings, with developers able to annotate these visual elements to guide the AI's understanding of desired changes. This visual feedback mechanism represents a substantial advancement over text-based interactions alone

Multi-Model Support and Availability

While built around Gemini 3 Pro, Antigravity supports multiple AI models including Anthropic's Claude Sonnet 4.5 and OpenAI's GPT-OSS, preventing immediate vendor lock-in and providing developers with model choice flexibility

The platform is currently available as a free public preview for Windows, macOS, and Linux, with what Google describes as "generous rate limits" for Gemini 3 Pro usage. Rate limits refresh every five hours, though some early users report hitting quotas faster than expected
