Google AntiGravity: Agent-First AI Development Platform

Google AntiGravity is a revolutionary AI-powered integrated development environment (IDE) designed for "agent-first" development. Instead of just offering smart autocompletion or code suggestions, AntiGravity deploys autonomous AI agents that plan, write, test, and validate code—handling complete workflows across the editor, terminal, and browser with minimal human intervention.

Core Capabilities

Agent-First Development

Unlike prompt-based assistants like GitHub Copilot, AntiGravity empowers multiple autonomous agents to execute entire coding features. Describe a high-level goal (e.g., "Build a flight booking app"), and agents will break it down, code, test, and iterate until completion.

Multi-Agent System

Multiple agents can work together, either in parallel or asynchronously, on different parts of a project (e.g., one agent codes, another tests, another refactors).

Mission Control and Workspace Manager

AntiGravity's interface includes a Manager view to launch, coordinate, and observe agent activity across projects and workspaces. Developers can monitor agent progress, review plans, and validate work via dedicated artifacts.

Artifacts for Trust

Agents produce tangible, verifiable deliverables—Markdown plans, screenshots, browser recordings—so you can check what the agent did at a glance, instead of sifting through logs.

End-to-End Automation

Agents can control the editor, terminal, and browser, enabling tasks like building, running, and UI testing to be performed automatically, with results fed back for validation.

Features

AI Model Flexibility

Built to work best with Google's Gemini 3 Pro model, but also supports others like Claude Sonnet 4.5 and open-source GPT-OSS, letting developers choose models that best suit their needs.

Modes of Operation

Autopilot: Full agent control for autonomous development
Review-Driven Mode: Requires approval before major changes
Hybrid Modes: Balanced approach for cautious developers

Cross-Platform Support

Available for Windows, macOS, and Linux, ensuring wide accessibility across development environments.

Verifiable Work Products

Generates artifacts including Markdown plans, screenshots, and browser recordings for transparency and trust validation.

Getting Started

Download AntiGravity from antigravity.google
Install the software and log in with a Gmail account
Configure your development mode and agent models
Use the Agent Manager to assign tasks and track progress
Review artifacts and provide feedback as needed

Practical Example

To build a simple app (e.g., Pomodoro timer), describe your goals and agents will: - Plan the architecture and implementation - Write the code automatically - Test functionality and fix issues - Help with UI design and backend setup - Provide deployment instructions

You stay in control, reviewing artifacts and giving feedback as needed.

How It Stands Out

Full Workflow Automation: Unlike line-by-line tools like Copilot or Cursor
Multi-Model Support: Flexibility to choose preferred AI models
Parallel Agent Orchestration: Multiple agents working simultaneously
Browser Integration: Testing and validation built into workflow
Safety and Transparency: Verifiable artifacts and supervision levels
Free Preview Access: Available at no cost during preview phase
