Cursor
Cursor is an AI-powered code editor built on top of VS Code that lets you write, edit, and debug code through natural language conversations. It's one of the most popular tools for vibe coding — combining a familiar editor interface with deep AI integration that understands your entire codebase.
Example
You open your Next.js project in Cursor, select a component, and press Cmd+K to tell the AI 'add a loading skeleton that matches the layout of this card.' Cursor reads the existing code, understands the structure, and generates a matching skeleton component in seconds.
Cursor has become the go-to editor for vibe coders. It takes the VS Code experience developers already know and adds AI capabilities that fundamentally change how you write code.
Key Features
- Chat — Ask questions about your codebase, get explanations, and request changes
- Cmd+K (Inline Edit) — Select code and describe what you want changed
- Composer — Multi-file editing mode for larger changes across your project
- Codebase awareness — AI reads and understands your entire project, not just the open file
- Cursor Rules — Custom instructions that shape how AI generates code for your project
Cursor vs Traditional Coding
| Traditional | With Cursor |
|---|---|
| Type every line manually | Describe what you want, AI writes it |
| Search Stack Overflow for solutions | Ask Cursor about your specific code |
| Debug by reading logs line by line | Paste the error, AI explains and fixes |
| Refactor file by file | Composer edits across multiple files at once |
Cursor Rules
One of Cursor's most powerful features. A .cursorrules file in your project root tells the AI:
- What frameworks and libraries to use
- Coding conventions to follow
- Patterns to prefer or avoid
- Project-specific context
This turns generic AI suggestions into code that matches your project perfectly.
