  2. Open your project
  3. Press Cmd+L for chat or Cmd+I for inline edit

Cascade plans the changes across multiple files, shows diffs, and applies them.


Intro

Windsurf is an AI-powered IDE by Codeium featuring Cascade — a multi-step agentic editing system that plans and executes complex code changes across multiple files with 6,000+ GitHub stars. Built on VS Code, it includes free access to Claude and GPT-4 for chat, autocomplete, and agentic flows. Unlike simple inline completions, Cascade understands your entire codebase and can orchestrate multi-file refactoring, feature additions, and bug fixes autonomously. Best for developers who want an AI IDE with strong agentic capabilities at a lower price than Cursor. Works with: Claude, GPT-4, Codeium models. Setup time: under 3 minutes.


Key Features

Cascade Flows

Multi-step agentic editing that plans before acting:

You: "Add rate limiting to all API endpoints"

Cascade:
Step 1: Analyzing 12 API route files...
Step 2: Creating rate-limit middleware (middleware/rateLimit.ts)
Step 3: Applying middleware to all route handlers
Step 4: Adding rate limit config to .env
Step 5: Writing tests for rate limiting

[Show diffs] [Apply all] [Apply selectively]

  • Understands your coding patterns
  • Predicts next logical change
  • Tab to accept, Esc to dismiss

"What tests cover the auth module?"
"Find all places where we handle errors"

Command Mode

Quick actions without leaving the editor:

Cmd+I: "Add TypeScript types to this function"
