TL;DR
Cursor wins for most developers. Its Tab autocomplete is more accurate, the Composer/Agent mode is more reliable for multi-file tasks, and the overall workflow feels more polished. Windsurf has a stronger free tier and a cleaner UI, but falls behind on complex agentic tasks.

What we tested
We ran both IDEs through 30 days of actual development work, including:
- Building a full-stack SaaS app from scratch
- Refactoring a legacy codebase
- Debugging sessions
- Writing tests
- Multi-file agent tasks
Every claim in this review is based on tasks we actually did, not vendor demos.
Cursor
Cursor is a fork of VS Code with AI baked in throughout. The two features you’ll use most are Tab (autocomplete that predicts your next edit, not just completions) and Composer/Agent (multi-file AI assistant you can give tasks to).
What’s great
Tab completion is genuinely predictive. Unlike GitHub Copilot which mostly predicts what you’re typing, Cursor Tab predicts your intent — it understands you’re refactoring and suggests the next logical edit. Once you get used to it, going back feels slow.
Agent mode handles complex tasks. “Add authentication to this Express app using JWT” works. It touches the right files, creates the right middleware, and doesn’t hallucinate dependencies. Not perfect — you still review everything — but the hit rate is high.
Context is excellent. Cursor is very good at figuring out which files are relevant. The @codebase and @file mentions let you be explicit, but most of the time it just… gets it.
What’s not great
It’s expensive. $20/month, and the free tier burns through quickly. If you’re a heavy user and frequently hit API limits, you either pay more or wait.
Occasional instability. Agent mode sometimes gets stuck in a loop. Less common than it used to be, but still happens on complex tasks.
Windsurf
Windsurf (by Codeium) launched in late 2024 as a serious Cursor competitor. Its standout feature is Cascade, which keeps a “flow” of context across your conversation rather than treating each message as isolated.
What’s great
Free tier is very generous. You get more free credits than Cursor, making it a better starting point for developers not ready to pay.
UI is cleaner. The Cascade panel feels less cluttered than Cursor’s Composer. Small thing, but it affects daily use.
Cascade context is interesting. Windsurf’s approach of maintaining a continuous context thread is clever — it remembers earlier decisions in the session and avoids contradicting itself.
What’s not great
Agent reliability is lower. On complex multi-file tasks, Windsurf broke things more often than Cursor. Not dramatically, but consistently.
Autocomplete is good, not great. Codeium’s completion engine is solid, but it doesn’t have the same “reads my mind” quality as Cursor Tab.
Pricing comparison
| Plan | Cursor | Windsurf |
|---|---|---|
| Free | 2-week trial, then limited | 200 credits/month |
| Pro | $20/month | $15/month |
| Business | $40/user/month | $40/user/month |
If cost is a major factor and you’re a lighter user, Windsurf’s free tier is genuinely usable. For professional use, both cost about the same annually.
Who should use what
Use Cursor if:
- You do serious, full-time development
- You frequently work across multiple files
- You’re willing to pay for the best autocomplete available
Use Windsurf if:
- You’re just getting started with AI-assisted coding
- You want to try before paying
- You prefer a cleaner, less busy UI
Final verdict
Cursor is the better tool for most professional developers. The autocomplete quality and agent reliability give it a meaningful edge in day-to-day work. But Windsurf is a legitimate alternative — especially on the free tier — and the gap has been closing.
If you’re new to AI coding assistants, start with Windsurf’s free tier. If you’re sold on the category and want the best, pay for Cursor.
