Antigravity: AI Programming Tool by Google DeepMind

Antigravity is an AI-assisted programming tool developed by the Google DeepMind team, integrating Google's advanced Gemini AI model series. It is designed specifically for autonomously completing complex programming tasks, capable of understanding your entire codebase and completing multi-step development tasks as an Agent.

What is Antigravity?

Antigravity's positioning is slightly different from Cursor—it is not just a "code completion assistant" but an autonomously working AI code agent:

Feature	Description
Agentic Workflow	Can autonomously plan and execute multi-step tasks without step-by-step guidance.
Full Codebase Understanding	Understands the code structure and context of the entire project, not just a single file.
Skills Packages	Inject professional knowledge into AI via Skill packages to generate code for specific domains accurately.
Task Tracking	Automatically records task progress, ensuring even complex tasks are completed methodically.
Multi-model Support	Natively integrates Gemini 3 series, while supporting switching between mainstream models like Claude 4.x and GPT-OSS.

Download and Installation

NOTE

Antigravity is typically provided as a VS Code extension or a standalone desktop application via the official website.

Method 1: VS Code Extension Installation

1. Open VS Code (if not installed, download from code.visualstudio.com).
2. Press Ctrl + Shift + X to open the Extensions marketplace.
3. Search for "Antigravity" in the search bar.
4. Click the Antigravity extension in the results and click Install.
5. Once installed, the Antigravity icon will appear in the left-hand sidebar.

Method 2: Download Desktop Version from Official Site

1. Visit the Antigravity official website and download the version for your OS.
2. Double-click the installer to complete the installation.
3. Log in with your Google account.

Registration and Activation

1. Click the Antigravity icon to bring up the login interface.
2. Select "Sign in with Google".
3. Use it immediately after authorization.

Pricing

Plan	Price	Includes
Free	$0/month	Limited AI chat requests; supports base models.
Personal Pro	~ $19/month	Unlimited AI usage; access to advanced models like Gemini 2.0/2.5 Pro.
Team	Custom Pricing	Team sharing; centralized administrative account management.

TIP

Recommended for Mbbrowser users: The Free version provides the full experience, and for Mbbrowser script generation, the free quota is usually sufficient for daily use. Upgrade to the Pro version for a better experience if you need to generate scripts frequently.

Core Usage Modes

1. Task-Driven (Recommended!)

The most powerful way to use Antigravity is to describe the task goal directly and let the AI autonomously complete the entire task:

1. Open the Antigravity panel (Ctrl + Shift + P → search for "Antigravity").
2. Click "New Task".
3. Enter your task description:

Using Mbbrowser Fingerprint Browser ApiServer, write a complete Python script to:
1. Read 10 Session_IDs from a configuration file.
2. Batch open these 10 Mbbrowser environments (concurrently).
3. Use Playwright to log in to https://shop.example.com in each environment.
4. Take a screenshot and save it, writing results (account/login success/screenshot path) to results.csv.
5. Close all environments upon completion.

Antigravity will:

• Autonomously analyze the task and formulate an execution plan.
• Create the necessary files in sequence.
• Adjust strategies automatically if issues arise.
• Present the final result to you upon completion.

2. Chat Mode

Similar to Cursor's Chat, enter your requirements in the dialog box, and AI provides the code.

Find the Antigravity Chat icon in the sidebar and enter:

Help me use Mbbrowser + Selenium to write a script for batch importing Cookies.

3. Inline Assistant

In a code file, select code, right-click → "Antigravity: Explain / Modify" to explain or rewrite the selected code.

Loading Mbbrowser Skills Packages (Crucial!)

Antigravity injects professional knowledge via Skills—this is similar to Cursor's Rules function but better suited for agentic workflow scenarios.

How to Configure Skills

1. Create a folder named .agent/skills/ in your Mbbrowser script project root.
2. Place the Mbbrowser Skills knowledge package file into this folder.
3. Antigravity will automatically recognize and load these skills.

TIP

For the complete content of the Mbbrowser Skills package, refer to the Skills & Prompt Templates chapter.

IMPORTANT

Dual-Package Synergy Principle: When configuring in Antigravity, ensure you provide both the Rules Package in the project context (or .cursor/rules/) and the Skills package. Rules provide API definitions, while Skills provide logic patterns; the two work together for 100% accurate code generation.

Supported AI Models (Latest as of Feb 2026)

Antigravity is an agent-first platform, deeply integrating the Google Gemini model series while supporting multi-model switching:

Model	Provider	Recommendation	Best For
Gemini 3 Pro / 3.1 Pro	Google	⭐⭐⭐⭐⭐ Most Popular	Default flagship model; generous free quota, strongest multimodal + Agent orchestration capabilities, leads SWE-bench benchmarks.
Claude Sonnet 4.6 / Opus 4.6	Anthropic	⭐⭐⭐⭐⭐ Second choice	Switch when strong reasoning or extreme code quality is required; many developers use Claude to supplement Gemini in Antigravity.
GPT-OSS-120B	OpenAI Variant	⭐⭐⭐	Privacy-sensitive or localized scenarios; open-source option.
Gemini 3 Flash	Google	⭐⭐⭐⭐	Lightweight and fast tasks; first choice within free quota.
Claude Legacy (4.5, etc.)	Anthropic	⭐⭐⭐	A stable fallback option.

TIP

Gemini 3 Pro is the absolute mainstream model in Antigravity (best optimized for free quota + Agent workflow). Claude Sonnet 4.6 is the runner-up—many developers manually switch to Claude when handling complex multi-step scripts for more rigorous logic.
