What is Antigravity? A Complete Beginner Guide
Overview
Antigravity is Google's AI-powered code editor that transforms how developers build software. Unlike traditional IDEs, Antigravity features an intelligent Agent that can understand complex requirements, plan implementations, and execute multi-step tasks autonomously.
What Makes Antigravity Different?
1. Intelligent Agent System
Antigravity's core feature is its AI Agent that goes beyond simple code completion:
- Task Planning: Automatically breaks down complex requests into manageable subtasks
- Autonomous Execution: Implements features, refactors code, and fixes bugs with minimal guidance
- Multi-Model Support: Choose from leading frontier models including Gemini 3 Pro, Claude Sonnet 4.5, and GPT-OSS
2. Task Groups for Complex Work
When you request something complex, Antigravity organizes work into Task Groups:
- Modular Breakdown: Large tasks split into smaller, focused units
- Parallel Processing: Multiple subtasks executed simultaneously
- Progress Tracking: Real-time visibility into what the agent is doing
- File Change Audit: Quick review of all modified files
3. Browser Subagent
Antigravity includes a specialized browser automation system:
- Web Interaction: Click, scroll, type, and navigate automatically
- Visual Testing: Capture screenshots and recordings
- Console Monitoring: Read and respond to browser logs
- Multi-Tab Support: Works in background tabs without interrupting your work
4. MCP (Model Context Protocol) Integration
Connect Antigravity to your entire development ecosystem:
Supported Integrations:
- Databases: MongoDB, Neon, Supabase, Redis, Prisma
- Project Management: Linear, Notion, GitHub, Atlassian
- Deployment: Netlify, Heroku
- Analytics: SonarQube
- Payments: Stripe, PayPal
- AI Tools: Perplexity Ask, Sequential Thinking
- Design: Figma Dev Mode, Locofy
The agent can fetch database schemas, create issues, search documentation, and execute custom tools.
5. Smart Artifacts System
Antigravity generates structured artifacts throughout development:
Task List
- Live snapshot of agent progress
- Tracks research, implementation, and verification
- Updates in real-time
Implementation Plan
- Detailed technical architecture
- Reviewable before execution
- Comment and provide feedback
- Request revisions or proceed
Walkthrough
- Summary of completed changes
- Screenshots and recordings for UI work
- Perfect for code reviews
How Antigravity Works
1. Start a Conversation
Open Antigravity and describe what you want to build:
"Create a user dashboard with profile management,
activity feed, and settings page"
2. Agent Creates a Plan
The agent analyzes your request and generates an Implementation Plan artifact showing:
- Files to create or modify
- Technical approach
- Architecture decisions
3. Review and Approve
- Comment on the plan if adjustments needed
- Click "Proceed" to start implementation
- Set auto-approval for trusted tasks
4. Watch Task Groups Execute
Multiple subtasks run in parallel:
- Component creation
- API endpoint setup
- Database schema updates
- Styling and layout
5. Get a Walkthrough
When complete, review:
- Summary of all changes
- Screenshots of new features
- Testing recommendations
Workspace Management
Multiple Projects
Work across several codebases simultaneously:
- Switch between workspaces instantly
- Separate conversation history per workspace
- Independent agent state
New Conversations
Start fresh conversations within a workspace:
- Previous context preserved
- Shared file access
- Clean agent state
Model Selection
Choose the right model for your task:
Gemini 3 Pro (High)
- Most capable for complex architecture
- Best for large refactors
- Slower but more thorough
Gemini 3 Pro (Low)
- Faster for routine tasks
- Good for simple features
- Cost-effective
Claude Sonnet 4.5
- Excellent code quality
- Great for documentation
- Strong reasoning
Claude Sonnet 4.5 (Thinking)
- Advanced problem-solving
- Complex debugging
- Deep analysis
GPT-OSS
- Open-source specialized
- Community patterns
- Library integration
Specialized Models
Antigravity uses additional models behind the scenes:
- Nano Banana: Generates UI mockups and images
- Gemini 2.5 Pro UI Checkpoint: Powers browser automation
- Gemini 2.5 Flash: Handles checkpointing and summarization
- Gemini 2.5 Flash Lite: Semantic code search
Key Features
Real-Time Context

- Reads recent deployment logs
- Searches your Notion/GitHub for patterns
Safe Execution
- Review plans before changes
- Comment system for feedback
- Rollback support
Progress Visibility
- Expandable subtask details
- Pending step approvals

Browser Integration
- Visual overlay during automation
- Protection from accidental interference
- Background tab operation
Common Use Cases
Feature Development
"Add user authentication with email/password and OAuth"
Bug Fixing
"Fix the memory leak in the data processing pipeline"
Refactoring
"Migrate from REST API to GraphQL"
Testing
"Write comprehensive unit tests for the payment module"
Documentation
"Generate API documentation from the codebase"
Database Changes

Getting Started
- Open Antigravity Editor: Access through your Google account
- Select or Create Workspace: Choose your project folder
- Start a Conversation: Describe your development goal
- Pick a Model: Select based on task complexity
- Review Plans: Check implementation approach
- Monitor Progress: Watch task groups execute
- Test Results: Verify the agent's work
Best Practices
Clear Instructions
Be specific about requirements:
- "Create a responsive navbar with logo, menu, and user dropdown"
- Include constraints: "Use Tailwind CSS and shadcn/ui components"
Leverage MCP
Connect relevant services before starting:
- Database for schema awareness
- GitHub for pattern discovery
- Linear for automatic issue creation
Review Plans
Don't auto-approve until you trust the agent's patterns:
- Check architectural decisions
- Verify tech stack choices
- Ensure scope alignment
Iterative Development
Break large features into phases:
- Core functionality
- Error handling
- UI polish
- Testing
Use Comments
Provide inline feedback on implementation plans:
- Request different approaches
- Add missing requirements
- Reduce scope if needed
