How to Switch from Claude Code to Windsurf (2026 IDE Migration Guide)

Updated: June 2026 · How we test tools →

You're switching from Claude Code to Windsurf. Most likely reason: you want a visual IDE with inline autocomplete and you don't want to pay $20/month for a terminal tool that gives you neither. Windsurf at $15/month — $5 less than Claude Code Pro — gives you a full AI-powered IDE, inline autocomplete via Codeium's Supercomplete, and a capable agentic Cascade system. It also has a free tier, which Claude Code has never offered.

This guide walks you through the full migration in about an hour.

What You're Gaining and Losing

You'll gain:

$5/month savings vs Claude Code Pro (Windsurf at $15 vs Claude Code at $20)
Inline autocomplete as you type — Claude Code has none
Visual inline diffs — accept/reject changes directly in the editor
A free tier to fully evaluate before committing
VS Code-familiar interface — your muscle memory transfers
Cascade agent for autonomous multi-file tasks inside the IDE

You'll lose:

Terminal-first workflow — Windsurf is a GUI editor
Claude model exclusivity — Windsurf uses its own model stack (Claude models not directly accessible without API)
JetBrains support — Windsurf is VS Code fork only
Claude Code's depth on the very hardest autonomous reasoning tasks

If you're weighing Windsurf against Cursor at the same decision point, the main differences are: Cursor is $5 more per month ($20) but has broader multi-model support; Windsurf is cheaper with a free tier but fewer model options. See Claude Code vs Windsurf → if you want the full comparison.

Step 1: Download and Install Windsurf

Go to codeium.com/windsurf and download Windsurf for your OS
Run the installer — it takes 2–3 minutes
Launch Windsurf

On first launch, Windsurf asks: Import settings from VS Code?

Say yes if you use VS Code. This imports:

All VS Code extensions (most are compatible)
Your keybindings (Cmd+P, Cmd+Shift+P — all your shortcuts carry over)
Themes and fonts
Editor preferences

If you've been using Claude Code exclusively in the terminal (not VS Code): choose a fresh setup. Windsurf's defaults are sensible. You can always configure further in Settings.

Step 2: Create a Free Windsurf Account

Windsurf requires an account to use its AI features.

On launch, click Sign In or Create Account
Use email or Google/GitHub sign-in
The free tier activates automatically — no credit card needed

Free tier limits: Windsurf's free tier gives you a limited number of Cascade agent interactions and autocomplete per day. It's enough to evaluate the tool on a real project before deciding to pay.

Upgrade to Pro ($15/month) when you're ready for full access. The upgrade is in Settings → Account → Upgrade.

Step 3: Get Familiar with the Windsurf Interface

Windsurf looks and feels like VS Code. The key AI additions:

Cascade panel — opens on the right sidebar (icon looks like flowing lines). This is Windsurf's agentic AI — the equivalent of Claude Code's autonomous agent. You describe tasks here and Cascade executes them.

Supercomplete — autocomplete that appears inline as you type (like GitHub Copilot). It activates automatically — no setup needed. Just start writing code and suggestions appear as ghost text. Press Tab to accept.

AI Chat — press Cmd+L (macOS) or Ctrl+L (Windows/Linux) to open the inline chat panel. Ask questions about your code, request explanations, or trigger quick edits.

The tab bar, file explorer, terminal, and Source Control are all identical to VS Code. If you've ever used VS Code, you're already familiar with 90% of the interface.

Step 4: Port Your CLAUDE.md Configuration

Claude Code reads CLAUDE.md automatically. Windsurf uses a different system for persistent project instructions.

Find your CLAUDE.md files

find ~/projects -name "CLAUDE.md" -type f

Windsurf's project context system

Windsurf reads context from:

.windsurfrules file in your project root — project-specific instructions
Global Rules in Settings → AI → Rules — apply to all projects

Create a .windsurfrules file in your project:

touch .windsurfrules

Convert your CLAUDE.md content:

# Project Rules (migrated from CLAUDE.md)
# These instructions apply to all AI interactions in this project.

[Paste your CLAUDE.md content here]

# Windsurf-specific additions:
When showing diffs, highlight the changed section clearly.
Before touching database migration files, show the full migration plan first.
Prefer editing existing files over creating new ones unless a new file is clearly required.

Example before and after:

CLAUDE.md:

This is a Next.js 14 App Router project with TypeScript and PostgreSQL (via Prisma).
Use server components by default. Only add "use client" when strictly necessary.
All API routes use Zod validation. Tests use Vitest and Testing Library.
Database: never edit migration files — generate new ones with prisma migrate dev.

.windsurfrules:

This is a Next.js 14 App Router project with TypeScript and PostgreSQL (via Prisma).
Use server components by default. Only add "use client" when strictly necessary.
All API routes use Zod validation. Tests use Vitest and Testing Library.
Database: never edit migration files — generate new ones with prisma migrate dev.
In Cascade: show a plan before making database-related changes.
For component files: always include TypeScript interface for props.

Global rules (for conventions that apply across all your projects): Settings → AI → Global Rules → paste cross-project conventions.

Step 5: Run Your First Cascade Task

Cascade is Windsurf's autonomous agent — the equivalent of Claude Code's agentic mode. Unlike Claude Code's terminal prompts, Cascade runs inside the Windsurf panel and shows diffs inline in the editor.

Open Cascade: Click the Cascade icon in the sidebar (or Cmd+Shift+L / Ctrl+Shift+L)

Try a task similar to what you'd do in Claude Code:

Implement a user authentication API endpoint with:
- POST /api/auth/login accepting email + password
- JWT token generation with 7-day expiry
- Refresh token stored in httpOnly cookie
- Proper error responses for invalid credentials
- Zod validation on the request body
- Test coverage in Vitest

What Cascade does:

Reads your codebase to understand the existing patterns
Plans the implementation (it may describe the approach in the panel)
Creates/modifies files — diffs appear inline in the editor
Shows accept/reject controls per file change

Key difference from Claude Code: Claude Code approval prompts appear in the terminal. Windsurf shows all changes as inline diffs in the editor — you click the green checkmark or X on each file, directly where the code lives.

Step 6: Configure Supercomplete Autocomplete

Supercomplete is Windsurf's inline autocomplete — Codeium's model trained specifically on code. It's already active after installation. Here's how to tune it:

Settings → AI → Supercomplete:

Suggestion speed: Fast (lower latency) vs. Thoughtful (higher quality, slightly slower)
Multi-line suggestions: Enable for function-level completions
Trigger: Automatic (default) or manual (Tab to request)

Using autocomplete:

Start typing any code — ghost text appears
Tab to accept the full suggestion
Escape to dismiss
Alt+→ (or Option+→ on Mac) to accept word by word

The next-edit prediction: Windsurf's Supercomplete predicts where your next edit should happen (similar to Cursor's tab-jump feature). After accepting a suggestion, press Tab again — it may jump to the next logically related edit location.

Autocomplete quality for common scenarios:

TypeScript interfaces and types: excellent
Framework idioms (Next.js, Express, FastAPI): strong
Test file generation: good
Complex generic types: adequate

Step 7: Workflow Mapping — Claude Code to Windsurf

Claude Code (terminal)	Windsurf equivalent
`claude "implement X"`	Cascade panel → describe task
Approval prompt in terminal	Inline diff in editor → click ✓ or ✗
`git diff` to review	Source Control panel (identical to VS Code)
CLAUDE.md project context	`.windsurfrules` file
`/clear` to reset session	New Cascade conversation (+ button in panel)
Long autonomous session	Cascade continues in background while you type
No autocomplete	Supercomplete works automatically as you type
Rate limit → pause	Windsurf Pro has generous limits at $15/month

The biggest shift: In Claude Code, you watch the terminal for progress. In Windsurf, you work in the editor normally — Cascade updates appear as inline diffs while you keep coding. Many developers find this less disruptive than watching a terminal scroll.

Step 8: Cost Comparison

	Claude Code	Windsurf
Monthly cost	$20 (Pro) — $100–200 (Max)	$15 (Pro)
Free tier	None	✅ Available
Autocomplete	No	Included
Rate limits	Hit after 3–5h on Pro	More headroom at $15
Models	Claude Sonnet/Opus	Windsurf's model stack

The $5/month saving is real. Over a year that's $60. More meaningfully: you get autocomplete included that Claude Code doesn't offer at any price.

If Claude Code's rate limits were your primary frustration, Windsurf Pro at $15/month with its Cascade agent plus Supercomplete often resolves both issues at a lower price. See Claude Code Rate Limits → and Claude Code Too Expensive? → for the full context.

What to Expect in Your First Week

Day 1: Open your main project, run Cascade on a small task you know well (write tests for a single function, refactor a small module). Compare the output to what you'd expect from Claude Code. Windsurf's Cascade is slightly less deep on hard reasoning but more visible in execution.

Day 2–3: Supercomplete autocomplete starts feeling essential. Tasks you were typing manually will start completing automatically. This is the biggest daily productivity gain over Claude Code.

Day 4–5: Configure .windsurfrules for each of your main projects. Once the project context is set, Cascade understands your conventions without re-prompting.

Week 1 end: Evaluate whether Windsurf's model depth is sufficient for your hardest tasks. For most everyday work — feature implementation, test writing, refactoring — it handles things well. For the most complex open-ended architectural tasks, Cascade's reasoning is somewhat shallower than Claude Code's best sessions.

If You Need More Model Depth

Windsurf's model stack is capable but not identical to Claude's reasoning quality on the hardest tasks. If you find specific complex tasks unsatisfactory:

Option A: Keep Claude Code for hard tasks only. Use Windsurf for daily work, open Claude Code in a terminal for specific complex sessions. Windsurf and Claude Code don't conflict.

Option B: Switch to Cursor instead. At $20/month (same as Claude Code), Cursor provides direct access to Claude Sonnet 4.5 and Opus, plus GPT-5 and Gemini. If model quality is critical, Cursor's multi-model access gives you more control than Windsurf. See our Cursor migration guide →.

Option C: Supplement with Aider. Keep Windsurf for IDE work + run Aider with Claude API in a terminal for hard reasoning tasks.

FAQ

Is Windsurf cheaper than Claude Code? Yes. Windsurf Pro is $15/month vs Claude Code Pro at $20/month — $5 less, with autocomplete included that Claude Code doesn't offer. The free tier also lets you evaluate properly before paying, which Claude Code has never allowed.

Does Windsurf use Claude's models? Windsurf uses Codeium's proprietary model stack, not Claude's models directly. If you want Claude models in a visual IDE, Cursor ($20/month) provides direct access to Claude Sonnet 4.5 via Anthropic. See Claude Code vs Cursor →.

Can Windsurf handle the same agentic tasks as Claude Code? For most everyday autonomous tasks — implement a feature, write tests, refactor a module — yes. For the hardest open-ended reasoning tasks on very large codebases, Claude Code's agent loop has a depth advantage. This matters for a minority of tasks.

Will my VS Code extensions work in Windsurf? Most do. Windsurf is a VS Code fork and imports extensions from your existing installation. A small number of proprietary extensions may not be compatible — check codeium.com/windsurf/extensions for the compatibility list.

How do I keep my project context across sessions? Create a .windsurfrules file in your project root with your conventions. Windsurf reads this automatically for every session — equivalent to Claude Code's automatic CLAUDE.md reading.

Can I use Claude Code and Windsurf at the same time? Yes. Many developers use Windsurf for daily IDE work and keep Claude Code installed for specific terminal-native tasks that benefit from its deeper reasoning. They don't conflict since they operate in different environments.
