Windsurf Setup Guide: Configure Your AI Coding Assistant in 2026

What Is Windsurf?

Windsurf is Codeium's AI-powered IDE built on VS Code, featuring Cascade — an agentic AI that can autonomously navigate your codebase, run terminal commands, and make multi-file edits. Think of it as having a senior developer pair programming with you, but one that never gets tired.

Installation & Initial Setup

Step 1: Download and Install

1. Visit windsurf.com and download for your OS
2. Install and launch — it imports your VS Code settings automatically
3. Sign in with your Codeium account (free tier available)

Step 2: Import Your Extensions

Windsurf supports most VS Code extensions. Your favorites likely work out of the box:

• ESLint, Prettier — ✅ works
• GitLens — ✅ works
• Tailwind CSS IntelliSense — ✅ works
• Language-specific extensions — ✅ generally compatible

Step 3: Configure AI Settings

Open Settings (Cmd+, / Ctrl+,) and search for "Cascade":

{
  "cascade.model": "claude-3.5-sonnet",
  "cascade.autoContext": true,
  "cascade.terminalAccess": true,
  "cascade.maxFileReads": 20
}

Key settings explained:

• autoContext — Cascade automatically reads relevant files before responding
• terminalAccess — Allow Cascade to run terminal commands (install packages, run tests)
• maxFileReads — How many files Cascade can read per turn

Understanding Cascade

Cascade is Windsurf's killer feature. Unlike tab-completion AI, Cascade:

1. Reads your entire codebase — understands project structure
2. Plans multi-step tasks — breaks complex requests into steps
3. Executes autonomously — creates files, installs packages, runs commands
4. Learns from context — gets better as it understands your project

Cascade Modes

Mode	Best For
Chat	Questions, explanations, planning
Write	Generating new code from scratch
Edit	Modifying existing code
Multi-file	Refactoring across multiple files

Configuring Cascade Rules

Cascade rules work similarly to Cursor rules — they guide the AI's behavior. Create a .windsurfrules file in your project root:

You are a senior developer working on a Next.js 14 SaaS application.

STACK:
- Next.js 14 (App Router)
- TypeScript strict mode
- Prisma + PostgreSQL
- Tailwind CSS
- Stripe for payments

CONVENTIONS:
- Server Components by default
- Server Actions for mutations
- Zod validation on all inputs
- Error boundaries around dynamic content

NAMING:
- Components: PascalCase (UserProfile.tsx)
- Hooks: camelCase with 'use' prefix (useAuth.ts)
- Utils: camelCase (formatCurrency.ts)
- API routes: kebab-case directories

TESTING:
- Vitest for unit tests
- Playwright for E2E
- Test files colocated: Component.test.tsx

Advanced Configuration

Custom Prompts per Workspace

Different projects need different rules. You can have workspace-specific configurations:

project-a/.windsurfrules  → React Native rules
project-b/.windsurfrules  → Python FastAPI rules
project-c/.windsurfrules  → Rust rules

Integrating with Your Existing Workflow

Git Integration

Cascade works beautifully with Git:

• Ask it to review your changes before committing
• Generate meaningful commit messages
• Create PR descriptions from diff summaries

Terminal Automation

Enable terminal access and Cascade can:

• Install dependencies (npm install, pip install)
• Run tests and fix failures
• Execute database migrations
• Start dev servers

Memory and Context

Windsurf maintains session memory. Tips for leveraging it:

1. Start sessions with context — "I'm working on the authentication module"
2. Reference previous conversations — "Like we discussed earlier..."
3. Build incrementally — Don't try to do everything in one prompt

Windsurf vs Manual Setup: Time Savings

Task	Manual	With Windsurf
New API endpoint	30 min	5 min
Component + tests	45 min	10 min
Refactor across 10 files	2 hours	15 min
Debug complex issue	1 hour	20 min

Troubleshooting Common Issues

Cascade Not Reading Files

• Check maxFileReads setting (increase to 30+)
• Ensure .gitignore isn't blocking needed files
• Try explicitly mentioning file paths in your prompt

Slow Response Times

• Close unnecessary tabs (reduces context size)
• Use specific prompts (less ambiguity = faster processing)
• Check your internet connection (Cascade uses cloud models)

Code Quality Issues

• Add more specific rules to .windsurfrules
• Include example code patterns
• Use negative rules ("NEVER use any type")

Conclusion

Windsurf is more than an IDE — it's a development multiplier. With proper setup and good Cascade rules, you'll spend less time on boilerplate and more time on what matters: building great products.
