Google Antigravity
Google • Integrated Development Environment (IDE)
AI is changing how we write code. Google Antigravity is an agentic development platform, moving beyond simple autocomplete to deploy autonomous AI agents that plan, execute, and verify complex engineering tasks across your entire workflow. It is a powerful integrated development environment (IDE). Built on a familiar code editor foundation, this platform integrates Google’s Gemini 3 Pro and other models to offer a new, task-oriented approach to software development, available free during its public preview phase.
This software shifts the focus from writing code faster to orchestrating entire tasks. Agents operate with greater autonomy, allowing developers to delegate complex UI iterations, bug fixes, and maintenance tasks to the system. Plus, the platform is cross-platform, supporting Windows, macOS, and Linux.

Google Antigravity Quick Start
Configuring Agent Auto-Execution Policy
- Click the Antigravity Settings button in the bottom-right corner.
- Locate the Auto Execution setting.
- Change the value from Request Review to Always Proceed to allow the agent to run terminal commands without explicit human permission.
Why: This setting is critical for power users who trust the agent’s logic, drastically speeding up the iteration cycle by removing synchronous human intervention for terminal commands and installations.
Customizing Agent Rules and Workflows
- To set a global rule, edit the markdown file at ~/.gemini/GEMINI.md.
- For workspace-specific rules, create or modify files within the your-workspace/.agent/rules/ directory.
- Define custom, long-running agent tasks by creating a new file in the your-workspace/.agent/workflows/ folder.
Why: Defining explicit rules and custom workflows allows developers to shape the AI’s behavior, enforce coding standards (e.g., comments in English), and delegate complex, multi-step maintenance tasks asynchronously.

Features
- Autonomous AI Agents: The platform utilizes an agent-first paradigm, allowing AI agents to autonomously plan, execute, and verify complex engineering tasks across the editor, terminal, and browser without constant human oversight.
- Artifacts for Trust: Agents generate verifiable Artifacts, such as task lists, implementation plans, screenshots, and browser recordings, which provide tangible proof of the agent’s logic and progress to build user trust.
- Multi-Model Support: Users can leverage multiple large language models, including Google’s pre-integrated Gemini 3 Pro, Anthropic’s Claude Sonnet 4.5, and an open-source variant of OpenAI models (GPT-OSS-120B).
- Agent Manager (Mission Control): A centralized interface, sometimes referred to as Mission Control, allows developers to monitor, manage, and assign tasks simultaneously to multiple autonomous agents, increasing traceability and control over development progress.
- Custom Rules and Workflows: Developers can define explicit Rules and Workflows at both the global and workspace levels to shape the agent’s behavior, enforce coding standards, and delegate long-running maintenance tasks asynchronously.
- Secure Mode: An optional Secure Mode enforces specific settings to prevent the agent from autonomously running targeted exploits and requires human review for all agent actions, enhancing security for sensitive projects.
Setup Instructions
Installation Steps
- Step 1: Click the download button above to get the installer for your operating system (Windows x64 is the primary target).
- Step 2: Locate the downloaded .exe file and double-click to run the installer; you may need to allow the app through Windows Defender SmartScreen.
- Step 3: Follow the on-screen installation wizard, accept the agreement, and select the destination location (the installation may require up to 701 MB of disk space).
- Step 4: Launch Google Antigravity and sign in with your personal Gmail account to begin using the agentic development platform.
Compatibility: Requires a 64-bit version of Windows 10 or later and a personal Gmail account for the public preview.
Fix Common Problems
- Issue: Agent fails to run terminal commands → Solution: Check the Auto Execution setting in Antigravity Settings and ensure it is not set to Request Review for every command.
- Issue: Rate limit exceeded error → Solution: The free preview is rate-limited; try slicing your work into smaller, more scoped tasks and use Rules to reduce back-and-forth agent loops.
Common Questions
Is Google Antigravity free to download and use?
Yes, Google Antigravity is currently available at no cost during its public preview phase for individuals with a personal Gmail account.
Do I need an API key for the AI models?
No API keys are required for Google’s Gemini 3 Pro model, as it is pre-integrated with the platform. However, using third-party models like Claude or GPT-OSS requires providing your own API keys.
What are Artifacts in Google Antigravity?
Artifacts are tangible deliverables, such as implementation plans, screenshots, and browser recordings, that the AI agent generates to communicate its work and allow the user to verify its logic at a glance.
