Windsurf IDE review: Cascade flows, AI-powered development features, comparison with Cursor, and why this under-the-radar AI code editor deserves your attention
The AI code editor space is dominated by two names: Cursor and GitHub Copilot. But there’s a third player that’s been flying under the radar and building a genuinely differentiated product: Windsurf IDE.
Developed by Codeium (the company behind the popular free Copilot alternative), Windsurf takes a fundamentally different approach to AI-assisted coding. Instead of augmenting a traditional editor with AI features, it rethinks the development workflow around AI-first principles.
What Makes Windsurf Different
Cascade Flows
This is Windsurf’s signature feature and its biggest differentiator. A Cascade flow is an agentic workflow that can plan and execute multi-step development tasks.
Unlike Cursor’s Composer (which generates code for you to review and apply), Cascade flows can:
- Plan a multi-step implementation strategy
- Create and modify multiple files
- Run terminal commands
- Read command output and adapt
- Run tests and fix failures
- Iterate until the task is complete
It’s closer to Claude Code’s agentic approach, but integrated into a visual IDE instead of a CLI.
How Cascade Works in Practice
User: Add user authentication to this Express app
using Passport.js with Google OAuth.
Cascade:
1. Analyzing project structure...
2. Installing dependencies: passport, passport-google-oauth20
3. Creating auth configuration file
4. Adding auth routes
5. Creating middleware
6. Updating the main app file
7. Adding environment variable template
8. Running tests...
9. All tests pass. Authentication added.
Each step is visible in the IDE, and you can intervene at any point. The flow pauses when it detects a decision point that needs human input.
