Problem: You Want AI-Native Coding Without Losing Your VS Code Setup
You've heard about Cursor's AI agents that write entire features while you sleep, but migrating your perfectly-tuned VS Code environment sounds painful.
You'll learn:
- How to import all VS Code settings in one click
- Which extensions transfer automatically vs. need alternatives
- How to start using Cursor's AI features immediately
- Common migration gotchas and fixes
Time: 30 min | Level: Beginner
Why Migrate to Cursor
Cursor is a VS Code fork built for AI-first development. Unlike GitHub Copilot (which adds AI to VS Code), Cursor rebuilt the entire editor around agents.
Key differences from VS Code + Copilot:
- Composer Mode: Describe a feature, AI builds it across multiple files
- Agent Workflows: AI runs Terminal commands, fixes errors autonomously
- Context Awareness: Understands your entire codebase, not just open files
- Plan Mode: AI creates implementation plans before coding
When to migrate:
- Working on complex refactors across many files
- Need AI to handle repetitive setup (APIs, boilerplate)
- Want agents that can debug and test independently
Pre-Migration Checklist
Step 0: Backup Your Current Setup
# Export VS Code settings
code --list-extensions > ~/vscode-extensions.txt
# Backup settings (optional)
cp ~/Library/Application\ Support/Code/User/settings.json ~/vscode-settings-backup.json
cp ~/Library/Application\ Support/Code/User/keybindings.json ~/vscode-keybindings-backup.json
Why this matters: Cursor uses a separate config directory — VS Code and Cursor can coexist without conflicts.
Location differences:
- VS Code config:
~/Library/Application Support/Code/ - Cursor config:
~/Library/Application Support/Cursor/
Solution
Step 1: Install Cursor
Download:
# Visit https://cursor.com and download
# Or use Homebrew (macOS)
brew install --cask cursor
First launch:
- Cursor detects existing VS Code installation
- Prompts: "Import VS Code extensions and settings?"
- Click "Import" — this copies 80% of your setup instantly
Expected: Welcome screen with import checklist completed
If it fails:
- VS Code Insiders: Cursor looks for stable VS Code first
- Remote extensions: SSH/DevContainer extensions don't auto-import
- Fix: Manually install from Open VSX (next step)
Step 2: Handle Extension Marketplace Differences
Critical detail: Cursor cannot use Microsoft's VS Code Marketplace due to licensing. It uses Open VSX Registry instead.
What transfers automatically:
- Open-source themes (Dracula, Material Theme)
- Language extensions (Python, Go, Rust)
- Formatters (Prettier, ESLint)
What needs alternatives:
| VS Code Extension | Cursor Alternative | Notes |
|---|---|---|
| C# Dev Kit (Microsoft) | Muon or OmniSharp | Proprietary to Microsoft |
| Remote - SSH | Built-in SSH support | Different config path |
| Live Share | Cursor Live Collab | Native feature in Cursor 2.0 |
| GitHub Copilot | Cursor AI (built-in) | No need to install |
How to find alternatives:
# Search Open VSX directly in Cursor
Cmd/Ctrl + Shift + X → Search "python"
Expected: Most extensions install identically
If missing:
- Search Open VSX at https://open-vsx.org
- Check Cursor community for recommended alternatives
Step 3: Configure Settings
Cursor uses the same settings.json format as VS Code.
Transfer custom settings:
Option A (recommended): Import during first launch Option B (manual):
# Copy your VS Code settings to Cursor
cp ~/Library/Application\ Support/Code/User/settings.json \
~/Library/Application\ Support/Cursor/User/settings.json
Key settings to verify:
{
// Editor preferences transfer directly
"editor.fontSize": 14,
"editor.tabSize": 2,
"workbench.colorTheme": "Dracula",
// Cursor-specific AI settings
"cursor.aiModel": "claude-sonnet-4-5", // or gpt-5-2, composer
"cursor.chat.enabled": true,
"cursor.tab.enabled": true // Advanced autocomplete
}
Cursor-specific additions:
{
// Enable Composer mode (AI builds multi-file features)
"cursor.composer.enabled": true,
// Agent can run terminal commands
"cursor.agent.terminalAccess": true,
// Codebase indexing for better context
"cursor.codebaseIndexing": "auto"
}
Expected: Settings UI looks identical to VS Code
Step 4: Set Up Cursor's AI Features
Choose your AI model:
Cursor supports multiple models:
- Composer (default): Fast, built for Cursor (4x speed vs GPT-4)
- Claude Sonnet 4.5: Best reasoning, great for refactors
- GPT-5.2: Good for creative solutions
- Local models: LLaMA, DeepSeek (privacy-focused)
Configure in Settings:
Cmd/Ctrl + , → Search "AI Model" → Select model
Set up API keys (if using Claude/GPT):
// settings.json
{
"cursor.anthropicApiKey": "sk-ant-...",
"cursor.openaiApiKey": "sk-..."
}
Or use Cursor's hosted API (easier):
- Sign up at cursor.com
- Billing based on usage (starts free)
Step 5: Learn Key Cursor Workflows
Basic AI interactions:
| Action | Shortcut | Use Case |
|---|---|---|
| Chat | Cmd/Ctrl + L | Ask questions about code |
| Inline Edit | Cmd/Ctrl + K | Edit selected code |
| Composer | Cmd/Ctrl + I | Build features across files |
| Agent Mode | Type /agent in chat | Autonomous debugging/testing |
Example Composer workflow:
1. Press Cmd/Ctrl + I
2. Type: "Add user authentication with JWT tokens"
3. Cursor:
- Creates auth.ts, middleware.ts
- Updates routes.ts
- Adds tests
- Shows plan before executing
4. Review diffs, merge changes
Agent Mode example:
Type in chat: /agent Fix all TypeScript errors in this project
Agent:
- Scans all .ts files
- Identifies type mismatches
- Runs `tsc` to verify fixes
- Opens PRs for review
Step 6: Set Up Cursor Rules (Optional but Powerful)
Cursor Rules = persistent instructions for AI across your project.
Create .cursorrules in project root:
# .cursorrules
language: typescript
framework: react
style: functional-components
guidelines:
- Always use TypeScript strict mode
- Prefer composition over inheritance
- Write tests for all new features
- Use Tailwind for styling
context:
- This is a Next.js 15 app
- We use tRPC for API routes
- Database: PostgreSQL with Prisma
Why this helps: AI follows your project conventions automatically
Load rules:
Cursor > Settings > Rules > Import .cursorrules
Step 7: Migrate Keyboard Shortcuts (If Customized)
Copy keybindings:
cp ~/Library/Application\ Support/Code/User/keybindings.json \
~/Library/Application\ Support/Cursor/User/keybindings.json
Default VS Code shortcuts work identically:
Cmd/Ctrl + P— Quick OpenCmd/Ctrl + Shift + F— Global SearchCmd/Ctrl + B— Toggle Sidebar
New Cursor-specific shortcuts:
Cmd/Ctrl + L— Open AI ChatCmd/Ctrl + I— Composer ModeCmd/Ctrl + Shift + L— Agent Mode
Step 8: Handle Edge Cases
Remote Development (SSH/DevContainers):
Cursor has built-in remote support:
File > Connect to Remote > SSH
Host: user@server.com
Extension not migrating?
Check Open VSX availability:
# Search on https://open-vsx.org
# If unavailable, check Cursor forums for alternatives
Performance issues with large repos?
// settings.json
{
"cursor.codebaseIndexing": "manual", // Disable auto-indexing
"cursor.maxFileSizeMB": 50 // Skip large files
}
Verification
Test your setup:
Open existing project:
cursor /path/to/your/projectTry AI chat:
Cmd/Ctrl + L Type: "Explain this file"Test Composer:
Cmd/Ctrl + I Type: "Add a logger utility function"
You should see:
- Extensions loaded correctly
- Theme applied
- AI responds to queries
- File explorer works identically to VS Code
If something's off:
- Check extension compatibility on Open VSX
- Verify API keys in settings
- Restart Cursor after importing settings
What You Learned
- Cursor is a VS Code fork — settings/shortcuts transfer directly
- Use Open VSX for extensions (not Microsoft Marketplace)
- Composer Mode builds multi-file features autonomously
.cursorruleskeeps AI aligned with your conventions
Limitations to know:
- Proprietary Microsoft extensions (C# Dev Kit) won't work
- First-time indexing can take 2-5 minutes on large codebases
- AI usage has costs (hosted API) or latency (local models)
When NOT to migrate:
- You only need basic autocomplete (stick with Copilot)
- Working on C#/.NET projects heavily tied to Microsoft tooling
- Offline-only development (Cursor's best features need internet)
Advanced Tips
Run Multiple Agents in Parallel
Cursor 2.0 supports parallel agents:
1. Open Agent Panel (View > Agents)
2. Create Agent 1: "Refactor authentication"
3. Create Agent 2: "Write tests for API routes"
4. Both run simultaneously in separate git worktrees
Use Cursor CLI for Automation
# Install Cursor CLI
npm install -g cursor-cli
# Run agent from terminal
cursor agent --task "Fix all ESLint errors" --auto-approve
# Generate code from command line
cursor generate --prompt "Create a login component"

Common Migration Issues
Issue 1: "Extension XYZ not found"
Cause: Extension only on Microsoft Marketplace
Fix:
# Search Open VSX alternative
https://open-vsx.org/search?query=extension-name
# Or ask Cursor AI
Chat: "What's the Cursor alternative to VS Code extension XYZ?"
Issue 2: Keybindings conflict with Cursor defaults
Fix:
// keybindings.json
[
{
"key": "cmd+l",
"command": "-cursor.chat.open", // Disable Cursor default
"when": "editorTextFocus"
},
{
"key": "cmd+l",
"command": "editor.action.selectLine" // Use your custom binding
}
]
Issue 3: Slow AI responses
Causes:
- Using remote models over slow connection
- Large codebase indexing incomplete
Fix:
{
"cursor.aiModel": "composer", // Switch to faster model
"cursor.codebaseIndexing": "manual",
"cursor.contextWindow": "medium" // Reduce context size
}
Cost Considerations
Cursor pricing (as of Feb 2026):
- Free tier: 50 AI requests/month
- Pro ($20/month): Unlimited AI, priority models
- Business ($40/user/month): Team features, custom models
Cost optimization tips:
{
// Use cheaper models for simple tasks
"cursor.autocompleteSuggestions": "composer", // Fast, free
// Reserve premium models for complex work
"cursor.agentModel": "claude-sonnet-4-5" // Only for /agent mode
}
Final Checklist
- Cursor installed and launched
- Extensions imported from VS Code
- Settings transferred
- AI model configured
- Test project opened successfully
- AI chat responds correctly
- Composer mode creates files
- Keyboard shortcuts work
You're ready to code with AI agents!
