Cursor for Vibe Coding: Complete Guide to AI-Powered Development

Why Cursor Is Central to Vibe Coding

Cursor is the tool that started the vibe coding movement. When Andrej Karpathy described vibe coding in February 2025, he was using Cursor with Claude. It is a fork of VS Code rebuilt around AI, and it has become the default code editor for anyone doing AI-assisted development.

Over 1 million developers use Cursor. It is the top AI code editor by market share and the one most commonly mentioned in vibe coding discussions. If you write code (or want to), Cursor should be your first stop.

How Cursor Works

Cursor looks and feels like VS Code. All your VS Code extensions, settings, and keyboard shortcuts work. The difference is three AI-powered features layered on top:

1. Tab (Autocomplete)

As you type, Cursor predicts what you are going to write next. Not just the current line, but entire functions, classes, and code blocks. It reads your project context (other files, imports, patterns) to make accurate predictions.

This is similar to GitHub Copilot but notably better at understanding project context.

2. Chat (Cmd+L / Ctrl+L)

Open the chat panel, ask a question or describe what you want, and Cursor responds with code. It reads your current file, selected code, and project context. You can ask things like:

• "Add error handling to this function"
• "Write tests for the UserService class"
• "Why is this component re-rendering?"
• "Refactor this to use the repository pattern"

Chat is great for targeted changes to specific files.

3. Composer (Cmd+I / Ctrl+I)

Composer is Cursor's multi-file editing tool. It is where vibe coding really happens. You describe a change that spans multiple files, and Cursor plans and executes it:

"Add a notification system. Create a notifications table in the database, a NotificationService with methods for creating and reading notifications, a REST endpoint at /api/notifications, and a bell icon in the header that shows unread count with a dropdown."

Composer creates all the files, writes the code, and shows you a diff of every change. You review and accept.

4. Agent Mode (the game changer)

Agent mode takes Composer to the next level. Instead of just generating code, the Agent can:

• Read and analyze your codebase
• Plan multi-step changes
• Execute terminal commands (install packages, run builds, execute tests)
• Fix errors automatically (reads error output, generates fix, retries)
• Make changes across dozens of files in a single task

This is the closest thing to having an AI developer working alongside you. You describe what you want, and the Agent figures out how to make it happen.

Practical Vibe Coding Workflow with Cursor

Here is how experienced vibe coders use Cursor:

Starting a New Project

1. Create a new folder and open it in Cursor
2. Open Composer (Cmd+I) in Agent mode
3. Describe your entire application:

"Create a Next.js 14 app with TypeScript, Tailwind CSS, and Prisma/PostgreSQL. The app is a freelancer invoicing tool. Features: create clients (name, email, company), create invoices (line items with description, quantity, rate), send invoices via email, mark invoices as paid, dashboard showing total revenue, outstanding invoices, and monthly chart. Use NextAuth for authentication with Google login. Deploy-ready for Vercel."

4. The Agent creates 30-50 files: pages, components, API routes, database schema, authentication config, everything.
5. Run npm install and npm run dev to see the result.

Iterating on Features

Use Chat (Cmd+L) for small changes:

• "Make the invoice PDF export include the company logo"
• "Add a due date field to invoices with a date picker"

Use Composer for larger changes:

• "Add a recurring invoices feature. Users can set an invoice to repeat monthly, quarterly, or annually. Create a cron job that generates new invoices from recurring templates."

Use Agent mode for complex cross-cutting changes:

• "Implement multi-currency support. Add a currency field to clients, convert all monetary values based on current exchange rates, update the dashboard to show totals in the user's default currency."

Debugging

When something breaks, paste the error into Chat:

"I am getting this error when trying to save an invoice: 'PrismaClientKnownRequestError: Foreign key constraint failed on the field: clientId'. Here is the relevant code [Cursor automatically includes the file context]."

Cursor reads the error, your schema, and your code, then tells you exactly what is wrong and generates the fix.

Cursor Settings That Matter

Model Selection

Cursor supports multiple AI models. For vibe coding:

• Claude 3.5 Sonnet / Claude 3 Opus: Best overall for code generation. Use this as your default.
• GPT-4o: Good alternative, slightly better at some frontend tasks.
• Cursor's own model: Fast for autocomplete, less capable for complex generation.

Set Claude as your default model for Chat and Composer. Use GPT-4o as a fallback when Claude's style does not match what you want.

Rules for AI

Cursor lets you define project-specific rules (in a .cursorrules file). This is powerful:

You are working on a Next.js 14 application using the App Router.
Use TypeScript strict mode.
Use Tailwind CSS for all styling, no CSS files.
Use Prisma for database access.
Follow the existing project structure.
Write tests for all new API routes using Vitest.
Never use any or unknown types.

These rules ensure every generation follows your project's conventions.

Context Configuration

Tell Cursor which files to index and which to ignore. In .cursorignore:

node_modules/
.next/
dist/
*.lock

This speeds up context loading and prevents the AI from getting confused by generated files.

Cursor vs. Other Vibe Coding Tools

Cursor vs. Spawned

Different tools for different stages. Spawned is better for initial generation (going from zero to working app). Cursor is better for refinement (taking an existing app and making it better). Many builders use Spawned to generate the initial app, export the code, and continue in Cursor.

Cursor vs. Windsurf

Windsurf is Cursor's main competitor. It is cheaper ($15/month vs $20/month) and has unique "Flows" feature. Cursor has better Agent mode and a larger community. For most users, Cursor is the safer bet, but Windsurf is worth trying if budget matters.

Cursor vs. GitHub Copilot

Copilot is primarily an autocomplete tool. Cursor's Chat, Composer, and Agent mode make it far more capable for vibe coding. Copilot is catching up with its agent features, but Cursor is ahead.

Cursor vs. Claude Code

Claude Code is a CLI tool that runs in the terminal. It has deeper codebase understanding and can execute commands directly. But it has no visual interface. If you are comfortable with terminals, Claude Code is more powerful. If you want a visual editor, Cursor wins.

Tips for Better Vibe Coding with Cursor

1. Start with Agent Mode for Big Tasks

For any task that touches more than 2-3 files, use Agent mode instead of Chat. Agent mode plans the changes holistically instead of file-by-file.

2. Be Explicit About What Not to Change

"Add a search feature to the dashboard. Do not modify the existing filter logic or change the data fetching approach." This prevents the AI from "helpfully" refactoring code you did not ask it to touch.

3. Review Diffs Carefully

Cursor shows diffs for every change. Actually read them. The AI is good but not perfect. Catch issues before they compound.

4. Use @mentions for Context

In Chat and Composer, use @ to reference specific files, folders, or documentation:

• "@schema.prisma" to include your database schema
• "@components/" to reference your component library
• "@docs" to reference project documentation

5. Keep a .cursorrules File Updated

As your project evolves, update your rules. If you adopt a new pattern, add it to .cursorrules so all future generations follow it.

Getting Started with Cursor

1. Download Cursor from cursor.sh
2. Import your VS Code settings and extensions
3. Open any project folder
4. Press Cmd+I to open Composer and start describing what you want
5. Start with a small change to get comfortable with the workflow

For complete beginners who do not have a project yet, start with Spawned to generate your initial app, then open it in Cursor for refinement.
