Overview
Google Antigravity is an AI-powered integrated development environment introduced by Google on November 18, 2025, alongside its advanced AI model Gemini 3. Built as a fork of Visual Studio Code, Antigravity represents a fundamental shift in software development by enabling developers to delegate complex coding tasks to autonomous AI agents that can plan, execute, and validate entire development workflows.
The platform is designed for developers who want to accelerate their coding productivity through intelligent automation. Rather than providing simple code suggestions, Antigravity allows AI agents to autonomously handle multi-step tasks across the editor, terminal, and integrated browser while maintaining full transparency through generated artifacts.
Antigravity is currently available in public preview at no cost for individual developers using personal Gmail accounts, with desktop builds for macOS, Windows, and supported 64-bit Linux distributions. It supports multiple AI models including Gemini 3 Pro, Anthropic's Claude Sonnet 4.5, and OpenAI's GPT-OSS open-weight models, giving developers flexibility in choosing the right model for each task.
Key Features
Agent-First Architecture — Shifts from traditional AI code completion to autonomous agents that plan, execute, and validate entire development tasks, allowing developers to focus on higher-level design and decision-making.
Dual Interface System — Combines a familiar VS Code-style Editor View for coding with an Agent Manager Dashboard for orchestrating multiple AI agents working simultaneously across different projects and workspaces.
Smart Artifacts Generation — Automatically creates comprehensive Markdown artifacts including task lists, implementation plans, code diffs, screenshots, and browser recordings, providing transparent insights into agent activities and enabling verification before changes are applied.
Cross-Surface Integration — Provides agents with direct access to the code editor, terminal, and an integrated browser surface powered by Chrome, enabling agents to test and validate web applications end-to-end.
Multi-Agent Orchestration — Manages multiple agents working asynchronously across different projects, enabling efficient handling of large codebases and parallel task execution.
Multi-Model Support — Supports Google's Gemini 3 Pro alongside Anthropic's Claude Sonnet 4.5 and OpenAI's GPT-OSS open-weight models, allowing developers to select the optimal model for specific tasks.
Pricing & Plans
Google Antigravity is currently in public preview and available free of charge for individual developers using personal Gmail accounts. This free access includes:
- Multi-agent support within generous per-window rate limits
- Integrated Gemini 3 Pro access in the IDE
- Complete integration with all development surfaces (editor, terminal, browser)
- Support for Windows, macOS, and supported Linux distributions
During the preview, Antigravity enforces fixed rate limits for Gemini 3 Pro usage that reset every few hours. Google expects most individual developers not to hit these quotas in typical workflows, but heavy multi-agent runs can and do reach the caps.
Future Pricing: Google has defined an Individual plan at $0/month during the public preview and signaled upcoming Team and Enterprise plans, but hasn't shared concrete pricing, feature tiers, or which capabilities will remain free once the preview ends.
Note: While Antigravity IDE is free during preview, developers using the Gemini 3 Pro API separately are charged $2 per million input tokens and $12 per million output tokens for prompts up to 200,000 tokens.
Pros & Cons

- Projects that benefit from parallel task execution across multiple codebases
- Developers seeking transparent AI assistance with verifiable artifacts and decision trails
- Early adopters willing to explore cutting-edge AI development tools during public preview
FAQ
Who can use Antigravity during the preview?
Antigravity is currently available as a desktop IDE for users with personal Gmail accounts, on macOS, Windows, and selected 64-bit Linux distributions. Google Workspace and some managed enterprise accounts are not yet supported in the public preview.
Is Google Antigravity free to use?
Yes, Antigravity is currently free during its public preview phase for individual developers using personal Gmail accounts. All core features are available at no cost, with generous — but not unlimited — rate limits on Gemini 3 Pro-powered agent runs. Google has signaled upcoming Team and Enterprise plans but hasn't disclosed when the preview will end or what the final pricing structure will be.
What operating systems does Antigravity support?
Antigravity is available for Windows, macOS, and Linux platforms. The IDE is built as a fork of Visual Studio Code, ensuring broad compatibility across operating systems.
Which AI models does Antigravity support?
Antigravity primarily uses Google's Gemini 3 Pro model but also supports Anthropic's Claude Sonnet 4.5 and OpenAI's GPT-OSS open-weight models. This multi-model approach allows developers to choose the most suitable model for specific tasks.
How does Antigravity differ from traditional AI coding assistants?
Unlike traditional AI tools that provide code suggestions or completions, Antigravity uses autonomous agents that can plan, execute, and validate entire development tasks. Agents have access to the editor, terminal, and browser, enabling them to handle complex multi-step workflows independently while generating transparent artifacts for developer review.
Are there rate limits during the public preview?
Yes. Antigravity applies time-windowed rate limits to Gemini 3 Pro usage that reset every few hours. Under normal individual workloads you're unlikely to hit them, but intensive multi-agent tasks can exhaust the quota until it resets.
Is my code and data secure with Antigravity?
Antigravity is currently a public preview and Google's own terms acknowledge known security limitations, including potential risks around data exfiltration and code execution. Recent security disclosures also showed that early builds were vulnerable before patches were released. Treat it as an experimental IDE: review the Antigravity Terms and Generative AI Terms of Service, configure data-sharing settings carefully, and avoid using it with highly sensitive or proprietary codebases until security guidance matures.
Can Antigravity agents work on multiple projects simultaneously?
Yes, the Agent Manager Dashboard allows developers to orchestrate and monitor multiple agents working across different projects and workspaces simultaneously. This enables asynchronous task execution and efficient handling of large codebases.
Does Antigravity work with existing VS Code extensions?
Antigravity is based on the open-source VS Code core and uses the OpenVSX registry by default. Many popular VS Code extensions work out of the box or via manual VSIX installation, but not every Marketplace extension is visible or fully compatible. You should test mission-critical plugins during the public preview to ensure they work as expected.
