Cursor vs Claude Code: When to Use Which

People ask me which AI coding tool is the best as if there is one answer. There is not. Cursor and Claude Code solve different problems in different contexts. Here is when I use each one, and why using both is not redundant.

Claude Code: The Terminal Agent

Claude Code lives in your terminal. You give it access to your entire project directory and direct it with natural language. It reads files, writes code, runs commands, installs packages, and commits changes. You never leave the terminal.

Best for:

• Greenfield projects: 'Build me a FastAPI app with CRUD endpoints for blog posts'
• Large refactors: 'Rename this module across the entire codebase and update all imports'
• Multi-file changes: 'Add error handling to every endpoint in the routers directory'
• Git workflows: Staging, committing, branch management, PR descriptions
• Exploration: 'Read the codebase and explain the database schema'

# Start a Claude Code session
cd my-project
claude
> 'Add a health check endpoint that returns the app version and uptime'

Cursor: The IDE Agent

Cursor is VS Code with AI built into every interaction. You highlight code, press a keyboard shortcut, and get context-aware suggestions. It sees your open files, your cursor position, and your recent edits.

Best for:

• Editing existing code: 'Refactor this function to use async/await'
• Inline completions: Tab-complete that understands your project's patterns
• Single-file work: Writing a complex algorithm, component, or data transformation
• Visual feedback: Seeing inline diffs before accepting changes
• Quick fixes: 'Fix the TypeScript error on line 42'

My Daily Split

A typical day looks like this:

| Time | Tool | Task | |------|------|------| | Morning | Claude Code | Scaffold new features, run full test suites | | Midday | Cursor | Fine-tune implementations, review and edit code | | Afternoon | Claude Code | Deploy, commit, create PRs, update docs |

The Key Difference

Claude Code is a project manager. You tell it what to build, and it figures out which files to create, what order to work in, and how to verify the result. It thinks at the project level.

Cursor is a pair programmer. You work together in real-time, line by line, file by file. It thinks at the code level, suggesting completions and edits based on immediate context.

When They Overlap

Both tools can write code. The difference is workflow:

• If you know which file to edit and roughly what to change, use Cursor
• If you know what you want but not where or how to implement it, use Claude Code
• If you need to understand a codebase before making changes, use Claude Code
• If you need precise control over a single function, use Cursor

My Recommendation

Start with Claude Code for project scaffolding and multi-file tasks. Use Cursor for daily editing and inline completions. Using both is the optimal setup for professional development work.
