What is Google Antigravity?

Google Antigravity explained: Antigravity is Google’s agentic development platform. AI agents plan programming tasks, write code, run terminal commands, and test web apps in a built-in browser. It consists of the Antigravity 2.0 desktop app, the Antigravity IDE, a command-line tool (CLI), and a Python SDK. It is free for individuals, with a weekly quota for agent work.

This guide covers what each component does, what Antigravity costs, how it compares with Cursor and Claude Code, and what businesses should check on data protection. It has nothing to do with the browser trick “Google Gravity” or with physics searches for “anti gravity”.

What’s New

• Antigravity 2.0 has arrived: The desktop app runs several agents in parallel, schedules background tasks, and accepts voice commands. 

• The CLI and SDK: A new CLI built in Go and an SDK for custom agent building (The Next Web).

• A new model: Google names Gemini 3.8 Flash as the engine of the platform and says it beats Gemini 3.1 Pro on coding and agent benchmarks.

• New subscription tiers: Google added a $100-per-month AI Ultra tier with five times the Pro limits, and the top tier dropped from $250 to $200/month (The Next Web).

• CLI Phasing Out: The legacy consumer Gemini CLI is officially being discontinued, and the Antigravity CLI GitHub repository has completely taken over its role.

Google Antigravity at a Glance

What Is Google Antigravity?

Antigravity answers a simple question: what does software development look like when agents, not people, do most of the typing? You describe a goal in plain language, for example, “build a sign-up page with email validation and test it”. The agent writes a plan, builds the code, starts the app, clicks through the interface, and fixes errors.

The key idea is “agent-first”. A classic editor assistant reacts to what you type. Antigravity agents work on their own for longer stretches and show their work as artifacts: an implementation plan, a task list, screenshots, and test results. You can comment on plans and results without touching the code. For the wider background, see our article on generative AI vs agentic AI and on agentic AI in software development.

Antigravity 2.0, IDE, CLI and SDK: The Components

Antigravity 2.0 and the Manager

Antigravity 2.0 replaces the editor with an overview where you start, watch, and approve several agents at once. This is the Manager view: one agent writes tests, another refactors, a third checks the layout in the browser. 

For multi-agent work in practice, read about multi-agent code review with Claude Code.

Antigravity IDE

The IDE is the classic editor with an agent side panel: tab completion, inline commands, and an agent for bigger tasks. If you prefer working in the code yourself, this is the one.

Antigravity CLI

The CLI brings the same agents to the terminal and replaces the Gemini CLI. For a primer on this tool class, see Gemini CLI vs Claude Code.

Key Features:

• Autonomous agents: Plan tasks, write code, run commands, and adjust the plan.

• Built-in browser: The agent launches your web app, fills in forms and checks the interface.

• Artifacts: Plan, task list and screenshots show what the agent did.

• Parallel agents: Several tasks run side by side in Antigravity 2.0.

• Tab completion and commands: Unlimited on the free plan.

• Scheduled tasks: Recurring work can be automated.

• Safety levels: Depending on the setting, the agent asks before running commands or works alone.

Which Models Does Google Antigravity Use?

Antigravity runs on Google’s Gemini models, currently working with Gemini 3.5 Flash and Gemini 3.1 Pro. It has also been working with the newest additions to the Gemini family, that is Gemini 3.8 Flash and Gemini 4 Argon (which is explicitly available for Google AI Pro and Ultra subscribers). Depending on the plan, third-party models such as Anthropic’s Claude and the open GPT-OSS are also available. You cannot bring your own API key or endpoint (Data Studios). For the differences between the Gemini models, see Gemini 3 vs Gemini Pro vs Deep Think and our article on Gemini 3 Flash. The model list changes quickly, so check the current one in the app.

Google Antigravity Pricing: Is It Free?

Yes, for individuals. The free plan includes unlimited tab completions and commands. Agent work is limited by a quota that refills every five hours until a weekly ceiling is reached. More capacity comes with Google’s AI plans.

The official Antigravity pricing page is the authoritative source. Google doesn’t publish fixed request counts: limits follow how much work the agent does, not how many prompts you send. The free quota has been reduced several times in the past (Vibecoding.app). If you run agents heavily, expect to need a higher plan or extra credits.

How to Install Antigravity in 5 Steps

1. Check requirements: Windows 10 (64-bit), macOS 12 or later, or 64-bit Linux. It runs on Mac and Windows alike.

2. Download: Get the desktop app or the IDE from antigravity.google.

3. Sign in: With a personal Google account. Workspace accounts often need a personal Gmail address.

4. Create a project: Grant access to one folder or repository. The agent works only inside it.

5. Give a first task: Describe the goal, review the plan in the artifact, and approve it.

Data collection is on by default, so review the privacy settings right after installing.

Testing Antigravity: What to Look For

A short test with four tasks shows whether it fits your work:

Antigravity vs Cursor vs Claude Code

For more information, read our articles on Cursor Composer 2.5 and GPT-5.2 Codex vs Claude Code.

Pick Antigravity if you want a free start and several agents in parallel. Pick Cursor when model choice and a mature editor matter. Pick Claude Code for terminal work with the newest Claude models.

Antigravity Alternatives

• Cursor: AI editor with wide model choice.

• Claude Code: Anthropic’s terminal agent.

• GitHub Copilot Workspace: Microsoft/GitHub's agentic environment for planning and building.

• Local models: When code must not leave your machine (see Ollama vs LM Studio).

Security and Data Protection (GDPR) for Businesses

Agents with access to a terminal, files and a browser are powerful, and that makes them a risk. Clarify three points before rollout:

1. Approvals: Use the strict setting with approval steps until the agent works reliably in your project. In the unchecked mode it runs commands without asking.

2. Prompt injection: Agents read web pages and documents, and crafted content can slip instructions to them. See our guide to prompt injection.

3. Data handling: Data collection is on by default. For individual accounts, no EU data residency is documented and no data processing agreement is offered. For business code, access through Google Cloud or a local setup is the safer choice. This is not legal advice.

Who Should Use Google Antigravity?

• Beginners and hobby developers: yes, thanks to the free plan.

• Development teams: yes, if you want to delegate tasks in parallel. Test limits and costs first.

• Companies with sensitive code: only with business access and a privacy review.

• Anyone who wants fixed prices and their own API keys: Cursor or Claude Code fit better.

Conclusion

Google Antigravity is one of the strongest free entry points into agentic software development. The multi-agent app Antigravity 2.0 is the biggest difference from classic editors. The weak spots are opaque limits and open data protection questions for business use. To see which models sit behind tools like this, read our overview of the best AI reasoning models in 2026.
