Windsurf AI Review: Cursor's Most Dangerous Competitor (And It's $5 Cheaper)
While everyone's been debating Cursor vs Copilot, Codeium's Windsurf has been quietly building something that's honestly better than either in some important ways. I used it for two weeks straight after being a Cursor diehard, and I came away genuinely impressed — and a little annoyed that I'd been paying $20/month for Cursor when Windsurf does 90% of the same things for $15.
What Is Windsurf, Actually?
Windsurf is Codeium's AI-powered IDE (well, it's a VS Code extension and a JetBrains plugin — you don't have to switch editors). Codeium started as a free Copilot alternative and evolved into Windsurf, which competes directly with Cursor's agent mode.
The headline feature is Cascade — Windsurf's multi-file editing mode that's conceptually similar to Cursor's agent mode but with some key differences in how it works.
Unlike Cursor, which is a VS Code fork that requires you to switch editors, Windsurf works inside your existing VS Code or JetBrains setup. This is a bigger deal than it sounds — if you have years of VS Code customizations, keybindings, and extensions, switching to Cursor means rebuilding all of that.
Cascade Mode: The Cursor Killer?
Cascade is Windsurf's answer to Cursor's agent mode, and honestly? It's better in some ways.
Where Cursor's agent mode feels like an AI that takes over your editor and does things, Cascade feels more collaborative. It shows you what it wants to do, explains why, and lets you approve or reject individual file changes rather than accepting/rejecting everything as a block. The diff view is cleaner, and the "reasoning" panel shows you what the AI is thinking before it touches your code.
In practice, Cascade made fewer mistakes than Cursor's agent mode on multi-file refactors. Cursor would occasionally make changes to files that "seemed right" but broke something subtle. Cascade's more conservative approach — showing intent before action — meant I caught potential issues before they became problems.
That said, Cursor's agent mode is faster when you trust it. Windsurf's extra confirmation steps add friction. If you're doing 20 small refactors, Cursor's speed wins. If you're doing 2 major refactors where correctness matters, Windsurf's caution wins.
The Pros
✅ Works in your existing editor. No VS Code fork, no relearning keybindings. Just install the extension and go.
✅ Cheaper. $15/month vs Cursor's $20. Not life-changing, but over a year that's $60 you could spend on something else.
✅ Better free tier. Windsurf's free tier is more generous than Cursor's. You get more Cascade actions and completions before hitting limits.
✅ JetBrains support. If you're an IntelliJ/PyCharm/WebStorm user, Windsurf works there. Cursor is VS Code-only.
✅ Safer multi-file edits. The confirmation workflow reduces "AI ran wild and broke things" incidents.
The Cons
❌ Smaller community. Fewer tutorials, fewer Stack Overflow answers, less momentum. Cursor's community is massive and helpful.
❌ Autocomplete isn't as fast. Copilot's inline completions are snappier. Windsurf's are good but have a slight delay that you notice after using Copilot.
❌ No "Composer" equivalent. Cursor's Composer mode (generate entire features from scratch) doesn't have a direct Windsurf equivalent. Cascade does multi-file edits but isn't as good at greenfield generation.
❌ Less polished UI. Windsurf's interface feels a bit clunkier than Cursor's. Not bad, just less refined.
Windsurf vs Cursor vs Copilot: Which Should You Pick?
Pick Windsurf if: You want the best value ($15/month), you use JetBrains, you prefer staying in your existing VS Code setup, or you want safer multi-file edits with more control.
Pick Cursor if: You want the best agent mode period, you do a lot of greenfield development (Composer is great for this), or you're willing to switch editors for maximum AI integration.
Pick Copilot if: You mostly want fast autocomplete, you're on a budget ($10/month), or your team is deeply integrated with GitHub.
🔮 Prediction: Windsurf is going to eat Cursor's lunch on price. When the feature gap between them is this narrow, $15 vs $20 matters. Cursor will need to either drop its price or pull further ahead on features. Competition is beautiful.
