Two AI-native IDEs, both built on VS Code, both promising to transform how you write code. Windsurf (by Codeium) and Cursor are the two leading options if you want an editor where AI is deeply integrated rather than bolted on.
I used both side by side for 30 days on real work — not toy projects. Here’s what I found.
The Quick Comparison
| Cursor | Windsurf | |
|---|---|---|
| Based on | VS Code fork | VS Code fork |
| Key feature | Composer (multi-file edits) | Cascade (agentic flows) |
| Autocomplete | Excellent | Good |
| Chat | Good | Good |
| Pricing | $20/mo Pro | $15/mo Pro |
| Free tier | Limited | Generous |
| Model support | GPT-4o, Claude, custom | GPT-4o, Claude, custom |
| Inline edits | Cmd+K, very polished | Similar, less polished |
| Project indexing | Fast, reliable | Fast, sometimes misses files |
What Cursor Does Better
1. Composer Is the Killer Feature
Cursor’s Composer lets you describe a change in natural language and it generates edits across multiple files. You see a preview of every change, accept or reject per file, and everything stays within your editor.
I’ve used Composer for things like: “Rename the UserService class to AccountService and update all imports,” “Add error handling to all API endpoints in src/routes/,” and “Convert this Express app to use async middleware.”
The multi-file diff preview is what makes it work. You see exactly what will change before committing. Windsurf’s Cascade can do similar things, but the preview and editing experience isn’t as tight.
2. Tab Completion Quality
Cursor’s autocomplete is slightly better than Windsurf’s in my experience. It picks up on project-specific patterns faster and the suggestions feel more contextually aware. The difference is small — maybe 10-15% better — but it adds up over a full day of coding.
3. Stability and Polish
Cursor has been around longer and it shows. The editor is stable, the AI features rarely glitch, and the keyboard shortcuts work consistently. Windsurf occasionally has quirks — the chat panel sometimes loses context after switching files, and the autocomplete can stutter on large projects.
4. Cmd+K Inline Edits
Highlight code, press Cmd+K, type what you want changed. This workflow in Cursor is very polished. Windsurf has a similar feature but it feels a step behind — slightly slower to respond and the edit suggestions aren’t always as accurate.
What Windsurf Does Better
1. Cascade’s Agentic Approach
Windsurf’s Cascade is different from Cursor’s Composer in a key way: it’s more autonomous. Where Composer generates edits for you to review, Cascade can chain multiple steps together — read files, understand context, make changes, run commands, and iterate.
For well-defined tasks (“add pagination to all list endpoints”), Cascade sometimes gets further without hand-holding. It’ll read your existing patterns, apply them consistently, and even run your tests to verify.
The downside: when it goes wrong, it can make a mess across multiple files before you catch it. I’ve had to git checkout . more than once after Cascade went confidently in the wrong direction.
2. Price
$15/month vs $20/month. Not a huge difference, but Windsurf also has a more generous free tier. If budget matters, Windsurf gives you more for less.
3. Built-In Terminal Integration
Windsurf’s terminal integration feels tighter — Cascade can run terminal commands as part of its workflow, see the output, and adjust. Cursor’s terminal is standard VS Code. This matters if you want the AI to run tests, check build output, or execute scripts as part of its work.
4. Codeium’s Free Autocomplete Legacy
Windsurf inherits Codeium’s autocomplete engine, which has been free and solid for years. The autocomplete in the free tier is genuinely usable — Cursor’s free tier is more limited.
The Deal-Breakers
Choose Cursor If:
- You want the best multi-file editing experience. Composer’s preview-and-accept workflow is more controlled than Cascade.
- You value stability. Cursor is more polished and has fewer rough edges.
- You mostly do code writing and editing. Cursor is optimized for this.
- You want the best autocomplete. Small edge, but it’s there.
Choose Windsurf If:
- You want more autonomous AI assistance. Cascade’s agentic flow can handle multi-step tasks without constant supervision.
- You’re on a budget. $15/month with a better free tier.
- You want terminal-integrated AI. Cascade’s ability to run commands is useful.
- You prefer Codeium’s ecosystem. If you’ve been a Codeium user, Windsurf is the natural upgrade.
What I Actually Use
I went back to Cursor after the 30-day trial. The main reasons:
- Composer’s preview gives me more confidence. I review changes before they land.
- The autocomplete is slightly better for my workflow (Python/TypeScript).
- Stability. I can’t afford my editor glitching during production debugging.
But I don’t think Windsurf is bad — it’s a legitimate alternative, and Cascade’s autonomous approach will appeal to developers who want AI to do more of the heavy lifting. If Windsurf tightens up the stability and the edit preview experience, the competition will be very close.

The Bigger Picture
The AI IDE space is moving fast. Both Cursor and Windsurf ship major updates monthly. The comparison above reflects my experience as of early 2026 — either tool could leapfrog the other with a single release.
My advice: try both for a week on real work (not a tutorial project). The “better” IDE is the one that fits your workflow, not the one that wins benchmarks.
