Switch from Cursor to Claude Code: Migration Guide

Why developers switch from Cursor to Claude Code

The decision to switch from Cursor to Claude Code usually starts with a specific frustration rather than a general desire for something new.

You hit a task where Cursor runs out of steam. A large-scale refactor that requires understanding 40 files at once. A CI pipeline you need fixed without copy-pasting error logs back and forth. A migration where the approach keeps changing based on what the tests actually reveal. You find yourself doing most of the work yourself, with Cursor offering suggestions rather than executing.

That is the signal. Cursor is an accelerator. Claude Code is a delegator. When your work shifts from "I want to write code faster" to "I want to stop executing and start directing," the migration makes sense.

This guide walks through the exact steps: what to install, what to port from Cursor, how your daily workflow changes, and the specific situations where switching is the wrong call.

For a broader feature comparison before committing, read the full Claude Code vs Cursor breakdown first.

What is actually different

Cursor is VS Code with AI embedded. It lives inside your editor, completes as you type, and offers a chat panel for multi-file edits. Everything stays visual. You review diffs, accept or reject changes, stay in the GUI flow.

Claude Code lives in your terminal. You describe a goal, it reads your entire codebase, plans the work, edits files, runs commands, checks output, and iterates until the task is done. There is no visual diff review by default. There is no inline autocomplete. The interface is a conversation in a terminal window.

This changes your relationship with the work:

Cursor	Claude Code
You stay in the editor	You move between editor and terminal
AI proposes, you review, you accept	You describe, AI executes, you verify
Diffs are visual and interactive	Changes land in your files, reviewed via git diff
Task scope is often single-file	Task scope can span the entire codebase
Works without a CLAUDE.md equivalent	Configuration compounds significantly over time

The learning curve is real. Developers who get frustrated with Claude Code in the first week are usually expecting Cursor in a terminal. It is not that. Once you internalise the delegation model, the experience is different in kind, not just in interface.

What to install

Start here. Everything else builds on a working installation.

npm install -g @anthropic-ai/claude-code

You need Node.js 18 or later. Check with node --version.

Authentication happens on first run. You have two options:

Anthropic API key. Go to console.anthropic.com, create a key, paste it when Claude Code prompts you. You pay per token. This is fine for light use and evaluation.

Claude Max subscription. $100/month for the 5x tier. This is the right choice if you plan to run autonomous sessions daily. The Max tier includes higher rate limits and Opus model access. Claude Code Pro at $20/month exists but is rate-limited for heavy agentic work.

Verify the install works by running claude in any project directory. It should read your codebase and respond to a basic question about the project structure.

The complete installation steps, including Node version management and authentication troubleshooting, are in the Claude Code setup guide.

What to port from Cursor

The most important migration task is converting your Cursor Rules into a CLAUDE.md file.

Converting Cursor Rules to CLAUDE.md

Cursor Rules live in .cursorrules or .cursor/rules/. They define your coding standards, project conventions, and model instructions. Claude Code uses CLAUDE.md for exactly the same purpose.

Open your rules file and copy the content into a new CLAUDE.md at your project root. Then rewrite for Claude Code conventions:

Cursor Rules style:

You are a TypeScript expert. Always use strict typing.
Never use `any`. Prefer functional patterns.

CLAUDE.md style:

## Tech stack
TypeScript (strict mode), React 18, Next.js 14 App Router, Drizzle ORM

## Code rules
- Never use `any`. Use `unknown` with type guards or explicit generics
- Prefer functional components with explicit prop types
- All async functions must handle errors explicitly. No swallowed promises

## Project structure
- Components: /src/components
- API routes: /src/app/api
- Database: /src/lib/db

Claude reads CLAUDE.md at the start of every session. More specific instructions produce more consistent output. Vague instructions produce vague behaviour.

For multi-project setups, you can also create a global CLAUDE.md at ~/.claude/CLAUDE.md for instructions that apply everywhere (your preferred git commit format, your style preferences, your debugging approach).

What does not migrate

Inline autocomplete. Claude Code does not do keystroke-level autocomplete. If you depend on Cursor's tab completion for writing code quickly, you will miss it. Many developers keep Cursor open for this purpose while using Claude Code for delegated tasks in a terminal alongside it.

Visual diff review. Claude Code's changes land directly in your files. You review them with git diff or by opening the files. If you rely heavily on Cursor's inline diff accept/reject flow, plan for an adjustment period.

Multi-model routing. Cursor lets you switch between GPT-5, Gemini, and Claude models mid-session. Claude Code runs on Anthropic models only.

How the workflow changes day to day

The biggest shift is in how you initiate and monitor work.

The old Cursor pattern

1. Open file in editor
2. Select code or type in chat
3. Describe what you want
4. Review diff, accept/reject changes
5. Repeat until done

The Claude Code pattern

1. Open terminal
2. Start a session with claude in the project directory
3. Describe the task at goal level, not step level
4. Let Claude execute, observe output, verify result
5. Use git diff to review all changes before committing

The key shift: Cursor tasks are scoped to what you can review inline. Claude Code tasks are scoped to what the codebase needs. You stop describing individual edits and start describing outcomes.

Refactoring: how it changes

Cursor workflow. Select the component, describe the refactor, review the diff per file. Good for single-component or single-concern refactors. You control each file change.

Claude Code workflow. Describe the refactor goal. Claude Code reads the full dependency graph, identifies all affected files, executes the changes across the codebase, runs your test suite, and fixes test failures that surface from the refactor.

For a rename-a-concept-across-30-files operation, this is not a marginal improvement. It is a different category of work.

Debugging: how it changes

Cursor workflow. Paste the error, get suggestions, apply manually, re-run, repeat. You are the test runner.

Claude Code workflow. Describe the symptom. Claude Code reads the relevant stack, identifies candidates, makes changes, runs your tests or the specific failing command, reads the output, and iterates. You watch the loop rather than driving it.

Multi-file edits: how it changes

Cursor workflow. Composer mode handles multi-file changes. Works well for feature additions where the scope is clear upfront. Less effective when the approach changes based on what the code reveals during execution.

Claude Code workflow. Multi-file edits are the native mode. Claude Code plans the full approach, adapts mid-execution when it discovers something unexpected, and runs verification automatically. The autonomy is the feature.

The migration checklist

Work through this in order. Each step takes 10-30 minutes.

Step 1: Install and authenticate (10 min)

• Install Claude Code via npm
• Authenticate with API key or Max subscription
• Run claude in one project directory to verify

Step 2: Create CLAUDE.md (20-30 min per project)

• Copy content from .cursorrules or .cursor/rules/ as a starting point
• Rewrite in imperative voice with specific project context
• Add tech stack, file structure, code conventions, testing instructions
• Add git workflow (branch naming, commit style, PR process)

Step 3: Set up global preferences (10 min)

• Create ~/.claude/CLAUDE.md for cross-project preferences
• Add your preferred coding style, debugging approach, commit format

Step 4: Install Claude Code skills (5-30 min depending on approach)

• Skills extend Claude Code with domain-specific knowledge for your stack
• The Claude Code skills library covers how to install and configure them
• For TypeScript, React, and Next.js projects, relevant skills provide significant quality uplift

Step 5: Run one real task (your first delegation)

• Pick a task you would normally handle in Cursor: a medium-complexity refactor, a debugging session, or a test backfill
• Describe it at goal level, not step level
• Observe how Claude Code approaches it and where it needs clarification
• This first session calibrates your expectations more than any documentation

Step 6: Set up git review habits

• Get comfortable using git diff and git status after Claude Code sessions
• Or use git add -p to review changes chunk by chunk before committing
• Claude Code can commit automatically if you ask it to, or you can keep commits manual

Common gotchas during migration

Gotcha 1: Prompting like Cursor chat. Cursor chat is designed for interactive back-and-forth where you refine the approach incrementally. Claude Code works better with goal-level descriptions upfront. "Fix the failing payments test" is better than "look at this test file and tell me what's wrong." Give it the whole picture, not a partial view.

Gotcha 2: Not reading the output. Claude Code narrates its reasoning as it works. Reading this output helps you catch wrong assumptions before they compound. Treat the terminal output as a conversation, not a spinner you ignore until it finishes.

Gotcha 3: Missing context in CLAUDE.md. Claude Code behaves as well as its context. A thin CLAUDE.md produces generic behaviour. If Claude Code keeps making choices you would not make, the fix is almost always more specific context in CLAUDE.md, not a better prompt.

Gotcha 4: Treating it as a fancier autocomplete. The delegation model requires a different mental frame. You are a technical director describing outcomes, not a developer directing every keypress. It takes a week or two to internalise. Resist the urge to give overly detailed step-by-step instructions.

Gotcha 5: Forgetting to verify. Claude Code's autonomous mode can produce large changes. Build a habit of reviewing with git diff before committing. The changes are usually correct, but autonomous execution without verification is how mistakes reach main.

Claude Code's hooks system lets you add automated verification gates to enforce this review step automatically.

When NOT to switch from Cursor to Claude Code

Switching is the wrong move in several common situations.

You write mostly new code. Feature development with fresh files is where Cursor's autocomplete shines. If most of your day is green-field work where the challenge is implementing something new, Cursor's flow-state support is a better fit than autonomous task delegation.

You need inline suggestions. If you want AI to complete your thoughts as you type, Claude Code is not the right tool. It is not designed for keystroke-level assistance.

Your team is not ready. Claude Code's autonomous execution produces large diffs. If your team reviews every AI-generated change carefully and relies on visual diff review in PR workflows, the switch requires changing review habits across the team, not just your local setup.

You primarily use a non-terminal editor. Vim, Emacs, or heavily customised editor setups that do not benefit from an adjacent terminal are less natural companions to Claude Code's workflow.

You are on the $20/month Pro tier and do heavy usage. The Pro tier's rate limits make long autonomous sessions impractical. Either the Max tier or careful task scoping is required.

The smartest use of both tools is keeping Cursor for flow-state coding and inline edits, and using Claude Code for complex delegated tasks. This is not hedging. It is matching each tool to what it is actually best at.

Setting up the hybrid: Cursor plus Claude Code

Most experienced developers land here. Cursor handles the daily editor experience. Claude Code handles the work you would rather delegate.

The practical setup:

• Cursor runs as your editor for writing and reviewing code
• Claude Code runs in a separate terminal window (iTerm split pane or Warp tab)
• Keyboard shortcut to switch focus between editor and terminal
• CLAUDE.md in every active project
• git diff reviewed before every Claude Code commit

This hybrid approach lets you migrate at your own pace. Start using Claude Code for one class of tasks (debugging, or test writing, or infrastructure setup) and expand from there as you build trust in the delegation model.

Claudify ships a complete Claude Code configuration stack: over 1,700 skills, persistent memory, and specialist agents pre-built. Instead of spending weeks building your CLAUDE.md library and skill configuration from scratch, you install one package and start with a battle-tested setup immediately.

The gap between a bare Claude Code installation and a properly configured one is large. The configuration work compounds over time, but there is a meaningful upfront investment in getting the setup right. The Claude Code best practices guide covers the full configuration surface and where to focus first.

Whether you build your own or use Claudify, the configuration layer is what separates occasional users from developers who treat Claude Code as essential infrastructure.
