The Agentic Paradigm
Understanding the shift from tools to partners.
Antigravity is built on three core pillars that define the "Agent-First" experience. This is not just about smarter autocomplete; it's about autonomy.
1. Mission Control & Asynchronous Orchestration
Instead of a single cursor, you have a Manager Surface. This allows you to spawn multiple specialized agents working in parallel. You might have one agent refactoring a legacy module, another writing unit tests for it, and a third researching a new library—all asynchronously. You act as the architect, reviewing their plans and outputs.
2. Verifiable Artifacts
Trust is the biggest barrier to AI adoption. Antigravity solves this with Artifacts—deliverables that are easier to validate than raw code.
- Task Lists: Agents break down high-level prompts into actionable steps.
- Implementation Plans: Detailed architectural roadmaps you approve before code is written.
- Browser Recordings: Video proof that the agent tested the feature and it works.
3. Self-Validation via Browser Control
Agents don't just write code; they run it. Using a dedicated Chrome extension and Gemini 2.5 Computer Use, agents can launch your app on localhost, click through the UI, fill out forms, and verify the actual user experience. If they encounter an error, they read the console logs, debug, and retry—without your intervention.
Antigravity Browser Control
Step-by-Step Details on how the agent interacts with the web.
1. Standalone Chrome Browser Automation
Antigravity can open, read, and fully control a Chrome browser to automate development tasks, test websites, and ingest internet data sources.
2. Subagent Structure
Managed via a dedicated Browser Subagent operating in its own window. Capable of:
- Navigating URLs
- Running automated tasks
- Extracting DOM content
- Triggering clicks & form submissions
3. Artifact Creation
The agent records actions as videos and captures screenshots. These are automatically attached to task lists and implementation plans for auditing.
4. Workspace Isolation
Runs in a Separate Chrome Profile to prevent security leakage. No account data, cookies, or history from your main browser are accessed. It appears as a distinct application in your dock.
5. Chrome Extension
Uses a specialized extension for secure control and recording. If Chrome isn't installed, you'll be prompted to download it.
6. Configuration
Enable/disable in project settings. You can manually specify the Chrome executable path if needed.
7. Security Controls
Manage access via Allowlists/Denylists to restrict which sites the agent can visit and interact with.
8. Usage Example
"Test the new login workflow in Chrome..."
- Opens isolated Chrome browser
- Navigates to target page
- Fills forms & clicks buttons
- Uploads visual artifacts for review
Model Context Protocol (MCP)
Stop the "Alt-Tab Dance". Connect your agent to your actual tools.
MCP is the open standard that powers AntiGravity's ability to understand your world. Instead of pasting code snippets into a chat window, you give the agent a direct, secure line to your Postgres database, your Vercel logs, or your GitHub issues.
Live Data
Agent queries your Supabase or Postgres DB to write accurate SQL.
Real Logs
Agent reads Vercel or Cloudflare logs to debug production errors instantly.
Action
Agent creates Linear tickets or opens GitHub PRs without leaving the IDE.
🔌 The Universal Connector
Connect any tool in minutes. Build your own server in TypeScript or Python.

Read Guide →Core Capabilities
Reimagining the entire developer experience.
Agent-First Paradigm
A dual-interface experience: A synchronous AI-powered Editor View for coding, and an asynchronous Manager Surface where you spawn and orchestrate agents.
Multi-Model Support
Powered by Gemini 3 Pro (54.2% on Terminal-Bench 2.0). Also supports Claude Sonnet 4.5 and OpenAI's GPT-OSS. Choose between "High" and "Low" reasoning tiers based on task complexity.
Verifiable Artifacts
Build trust with verifiable deliverables. Agents produce Implementation Plans, Task Lists, and Browser Recordings so you can verify their work before merging.
Interactive Feedback
Guide agents with Google-doc-style comments. Leave feedback directly on artifacts or screenshots to steer the agent's direction without restarting the task.
Self-Improving Agents
Agents maintain a persistent Knowledge Base. They remember successful snippets, architectural patterns, and your preferences from previous tasks.
1M+ Context Window
Understand and refactor entire monorepos. With Gemini 3's massive context, agents can read every file in your project to ensure global consistency during refactors.
Our Philosophy
Built on four core tenets to enable true agentic development.
Trust
We believe AI should be verifiable. Antigravity exposes the "thought process" of agents through artifacts.
Autonomy
Agents are not just chatbots. They have full access to the editor, terminal, and browser.
Feedback
Steering an agent should be as natural as code review. Provide feedback directly on artifacts.
Self-Improvement
Your agents get smarter with every task. By maintaining a persistent knowledge base.
Agent-First Architecture
Three interconnected surfaces working in perfect synchronization.
1. Agent Manager
Mission Control. The central command center for orchestrating multiple AI agents.
2. Editor View
Familiar & Fast. A VS Code-based interface enhanced for agent collaboration.
3. Browser Control
Verification Surface. The killer feature. Agents use a dedicated Chrome extension.
Trust Through Transparency
Building confidence with the Artifacts System.
Most AI tools are black boxes. Antigravity changes this with Artifacts.
📋 Task Lists
Agents break down high-level prompts into actionable subtasks.
📝 Implementation Plans
Detailed roadmaps and architectural decisions.
📸 Verification
Screenshots and browser recordings proving the feature works.
Model Context Protocol (MCP)
The universal standard for connecting AI to your world.
1. MCP Host
The AI application (Antigravity) that initiates connections. It discovers available tools and resources.
2. MCP Client
The translator inside the host that maintains 1:1 connections with servers, handling the protocol handshake.
3. MCP Server
External services (GitHub, Postgres, Local Files) that expose "Resources", "Prompts", and "Tools" to the AI.
4. Transport Layer
The communication pipe. Antigravity supports standard input/output (STDIO) for local processes and HTTP/SSE for remote servers.
Building Custom MCP Servers
from mcp import Server
# Create an MCP server
mcp = Server("Hello World")
@mcp.tool()
def greet_user(name: str) -> str:
"""Greet a user by name"""
return f"Hello, {name}! Welcome to MCP."
if __name__ == "__main__":
mcp.run(transport="stdio")Real-World Agent Workflows
From prompt to production: How an agent builds a Flight Tracker App.
1. Planning Phase
The agent generates a task list, creates an implementation plan with architecture decisions, and identifies necessary dependencies.
2. Development Phase
It writes the backend API code, creates frontend components, sets up database schemas, and even generates visual assets using Nano Banana.
3. Testing Phase
Autonomous Verification: The agent launches localhost, opens a Chrome browser, tests features, and takes screenshots of the working app.
4. Verification Phase
Finally, it generates a walkthrough document and records a video demonstration for your review.

Best Practices
How to get the most out of your agentic workflow.
1. Start with Clear Goals
Provide clear project goals rather than step-by-step instructions.
2. Review Artifacts
Always review task lists and implementation plans before allowing agents to proceed.
3. Use Multiple Agents
Spawn one for frontend, one for backend, and one for research—all running in parallel.
4. Leverage Browser Verification
Let agents use the browser to validate their own work.
