Andrej Karpathy coined “vibe coding” in February 2025: describe what you want, let the AI write the code, accept everything, and fix what breaks. Cursor is the most popular IDE for this workflow. This guide covers how to set it up, what works, what doesn't, and when you should use something else.
What Is Vibe Coding?
Vibe coding means telling an AI what to build in plain language and letting it handle the implementation. You describe features, accept the generated code without reading every diff, copy-paste error messages back when things break, and iterate until the result works. Karpathy's original description: “fully give in to the vibes, embrace exponentials, and forget that the code even exists.”
The term was significant enough that Collins English Dictionary named it Word of the Year for 2025. It works well for prototypes, weekend projects, and internal tools. For production software, you still need to understand the code your AI writes, but the starting point is fundamentally different from writing it yourself line by line.
Vibe Coding vs. AI-Assisted Coding
They are not the same thing. AI-assisted coding means you write code and the AI helps (autocomplete, suggestions, refactoring). Vibe coding means the AI writes the code and you steer. Cursor supports both: Tab completions for AI-assisted coding, Agent mode for vibe coding.
How Cursor Enables Vibe Coding
Cursor has four features that make it the tool most developers reach for when vibe coding. Each removes a different friction point between “describe what you want” and “see it working.”
Agent Mode
The default mode in Cursor. It reads your codebase, edits files across your project, runs terminal commands, browses documentation, and installs packages. You describe a feature; it figures out which files to touch and what to change.
Background Agents
Triggered with Ctrl+E. The agent runs in a cloud sandbox and auto-executes all commands without waiting for your approval. You can close the tab and come back when it is done. Useful for long-running tasks like test suites or large refactors.
Subagents
Introduced in Cursor 2.4 (January 2026). Independent parallel workers that each handle a discrete part of a task. A refactor that would take one agent 10 minutes can finish in 2-3 minutes with multiple subagents working simultaneously.
YOLO Mode
Removes all confirmation dialogs. The agent runs terminal commands, deletes files, and installs packages without asking. Fastest iteration speed, but no safety net. Best for sandboxed environments or throwaway prototypes.
Together, these features let you describe a full feature in natural language and watch Cursor build it across multiple files, running tests and fixing errors as it goes. That is the core vibe coding loop.
Setup Guide: How to Start Vibe Coding with Cursor
1. Install Cursor
Download from cursor.com. It runs on macOS, Windows, and Linux. Cursor is a VS Code fork, so your extensions, themes, and keybindings carry over.
2. Open Your Project and Select Agent Mode
Open any project folder. Press Cmd+L (Mac) or Ctrl+L (Windows/Linux) to open the chat panel. In the mode dropdown at the top, select Agent. This is the mode you want for vibe coding. The other modes (Ask, Manual, Edit) are for more targeted work.
3. Configure Rules for AI
Go to Settings > Features > Chat & Composer > Rules for AI. Add project-specific instructions that persist across sessions. This is where you set coding style, framework preferences, and architectural constraints.
Example .cursorrules file
# Project Rules
- Use TypeScript strict mode
- React functional components only
- Tailwind CSS for styling, no inline styles
- All API calls go through src/lib/api.ts
- Run "npm test" after any code change
- Commit messages use conventional commits format4. Add a .cursorignore File
Create a .cursorignore file in your project root. Excluding node_modules, build artifacts, and large binary files gives you a 30%+ speed boost because the agent indexes less.
.cursorignore
node_modules/
.next/
dist/
build/
*.lock
*.png
*.jpg
*.mp45. Enable YOLO Mode (Optional)
For maximum vibe coding speed: Settings > Features > Chat & Composer > Enable YOLO mode. The agent will execute commands without confirmation. Only do this in sandboxed environments or projects where you can easily roll back with Git.
6. Start Building
Type your first prompt. Be specific about what you want. “Build a dashboard page with a sidebar, a chart showing monthly revenue, and a table of recent orders using shadcn/ui components” works much better than “make a dashboard.”
Tips and Best Practices for Vibe Coding in Cursor
Commit before every agent run
Git is your undo button. If the agent makes a mess, you can reset to the last good state in seconds. Without commits, you are stuck trying to untangle the AI's changes from your own.
Keep tasks to 3-5 files
Large tasks degrade agent performance. Split 'build the entire auth system' into 'create the login form,' 'add the JWT middleware,' and 'wire up the protected routes.' Smaller tasks get better results.
Start new chat sessions often
Cursor's context window fills up as the session grows. Long sessions cause the AI to lose track of earlier context, repeat itself, or contradict previous work. Start fresh when you switch tasks.
Use @-mentions for context
Type @filename to pull specific files into context. Type @docs to reference documentation. Type @web to let the agent search the web. Targeted context beats dumping everything into the window.
Plan with a reasoning model, build with Composer
Use Claude or o3 for high-level planning (architecture, data models, API design). Then switch to Cursor's fast Composer model for execution. This two-model pattern is explicitly supported in Cursor.
Review aggregated diffs before accepting
Even in vibe coding mode, glance at the aggregated multi-file diff before hitting Accept All. Catching a wrong file edit takes 5 seconds here vs. 30 minutes of debugging later.
Execution Mode Strategy
| Mode | What It Does | Best For |
|---|---|---|
| Agent (default) | Reads codebase, edits files, runs commands with your approval | Most vibe coding tasks |
| YOLO | Agent mode without any confirmation dialogs | Prototyping, sandboxed projects |
| Background Agent | Runs in cloud sandbox, auto-executes everything | Long tasks (test suites, big refactors) |
| Manual | You control every edit, agent only suggests | Production code, sensitive files |
| Ask | Agent answers questions without editing files | Understanding code, planning |
Where Cursor Falls Short for Vibe Coding
Cursor is the best general-purpose vibe coding tool in 2026. But it has real limitations, and knowing them upfront saves you from hitting walls mid-project.
Context window degradation
As your session grows (more files, more history, more rules), the AI's performance drops. It misses dependencies, produces inconsistent code, and starts ignoring earlier instructions. You have to start new sessions to reset this.
Wrong file edits
The agent sometimes modifies files you did not ask it to touch. In large codebases with similar file names or patterns, it picks the wrong target. Always review the file list in diffs before accepting.
Security vulnerabilities in generated code
CodeRabbit research found approximately 45% of AI-generated code contains vulnerabilities. SQL injection, XSS, improper auth handling. Vibe coding makes this worse because the whole point is not reviewing every line.
Cost creep beyond $20/mo
Cursor switched to credit-based billing in 2025. Your $20/mo Pro plan includes a $20 credit pool. Every premium model call deducts from it. Heavy vibe coding sessions burn through credits fast, pushing real costs to $40-60/mo.
The 70/30 gap
Cursor gets you about 70% of the way to a working app. The last 30% (edge cases, error handling, performance, deployment) still requires real development skills. Vibe coding is not a replacement for knowing how to code.
VS Code fork lock-in
Cursor is a proprietary VS Code fork. Your settings, extensions, and workflows are tied to Cursor's release schedule. If you want to switch to JetBrains, Neovim, or standard VS Code, your AI features do not come with you.

Cursor vs Lovable vs Bolt vs Replit for Vibe Coding
These four tools represent different approaches to vibe coding. Cursor is a professional IDE with AI agents. Lovable and Bolt are browser-based app builders. Replit is a cloud development environment. Each fits a different use case.
| Feature | Cursor | Lovable | Bolt.new | Replit |
|---|---|---|---|---|
| Type | Desktop IDE (VS Code fork) | Browser app builder | Browser app builder | Cloud IDE |
| Time to first prototype | ~65 min | ~35 min | ~28 min | ~45 min |
| Max project complexity | Hundreds of files | ~15-20 components | ~15-20 components | ~30-40 components |
| Code quality | Production-ready | Needs cleanup | Needs significant cleanup | Moderate |
| Git integration | Full (local Git) | Basic export | Basic export | Built-in |
| Custom backend/DB | Yes (any stack) | Supabase only | Limited | Yes (many languages) |
| Deployment | You handle it | One-click | One-click | Built-in hosting |
| Starting price | $20/mo | $20/mo | $15/mo | $0 (free tier) |
When to Use Each Tool
- Cursor: You know how to code (or are learning) and need something that scales past a prototype. Multi-file edits, Git, testing, deployment pipelines. This is where you build things that need to survive real users.
- Lovable: You are non-technical and want to validate a product idea with a working demo. Good for landing pages, simple CRUD apps, and MVPs that talk to Supabase.
- Bolt.new: You need a throwaway prototype by tomorrow. Fastest to first working version, but the code quality makes it hard to iterate beyond the initial demo.
- Replit: You are learning to code or want a cloud environment for experimentation. Good for trying different languages and frameworks without local setup.

Cursor Pricing for Vibe Coding (2026)
Cursor switched to credit-based billing in mid-2025. The plan you need depends on how heavily you vibe code.
| Plan | Price | What You Get | Vibe Coding Fit |
|---|---|---|---|
| Hobby | Free | Limited agent requests, limited tab completions | Testing only |
| Pro | $20/mo | $20 credit pool, unlimited tabs, background agents | Light to moderate vibe coding |
| Pro+ | $60/mo | 3x usage of premium models | Daily vibe coding sessions |
| Ultra | $200/mo | 20x usage, priority access | All-day heavy vibe coding |
Most developers who vibe code regularly land on Pro ($20/mo) or Pro+ ($60/mo). The free Hobby tier is too limited for real vibe coding because agent requests run out quickly. If you hit credit limits on Pro, the $60 Pro+ tier is a better deal than paying overages.
Annual billing saves 20% across all paid tiers. Teams start at $40/user/month.
Frequently Asked Questions
What is vibe coding in Cursor?
Vibe coding is a style of AI-assisted development where you describe what you want in natural language and let Cursor's agent mode generate, edit, and run code autonomously. The term was coined by Andrej Karpathy in February 2025. In Cursor, you use Agent mode, Composer, and YOLO mode to build features without manually writing most of the code.
How do I start vibe coding with Cursor?
Download Cursor from cursor.com, open your project, and press Cmd+L (Mac) or Ctrl+L (Windows) to open the chat panel. Select Agent mode from the dropdown. Describe what you want to build in plain English. For faster iteration, enable YOLO mode in Settings so the agent runs commands without asking for confirmation each time.
Is Cursor good for vibe coding?
Cursor is the most popular IDE for vibe coding because of Agent mode, subagents for parallel work, background agents for cloud execution, and deep codebase understanding. It handles complex multi-file projects better than browser tools like Lovable or Bolt. The main downsides are context window limits on large projects and pricing that can exceed $20/mo with heavy usage.
What is YOLO mode in Cursor?
YOLO mode lets Cursor's Agent mode execute terminal commands and delete files without asking for confirmation. Enable it in Settings > Features > Chat & Composer. Useful for rapid prototyping and sandboxed environments, but risky for production code since the agent can make destructive changes without a safety net.
How does Cursor compare to Lovable and Bolt for vibe coding?
Bolt reaches a working prototype fastest (under 30 minutes) and Lovable works best for non-technical users validating ideas. Both tools hit a complexity wall around 15-20 components where the AI loses context. Cursor handles much larger codebases and produces more production-ready code because you work in a full development environment with Git, linting, and testing. See our full vibe coding tools comparison.
What are the limitations of vibe coding with Cursor?
The main limitations: context window degradation on long sessions, the AI modifying wrong files, approximately 45% of AI-generated code containing vulnerabilities (per CodeRabbit research), pricing overages beyond the base $20/mo plan, and the fact that you still need development skills to ship the last 30% of any non-trivial project to production.
Better Code Search for Better Vibe Coding
WarpGrep is a semantic code search MCP server that improves any AI coding agent's performance by ~4% on SWE-bench. It works inside Cursor, Claude Code, Windsurf, and any tool that supports MCP. Better search means your agent finds the right context faster and writes better code.
