Cursor vs Windsurf

Both produce good code — choose based on workflow preference. Code quality differences are marginal. Either way, review AI-generated code for security before production.

Cursor and Windsurf are both AI-powered IDEs (VS Code forks) competing for the same market — developers who want agentic AI assistance while coding. Both can generate multi-file features, run terminal commands, and understand your full codebase. The code quality differences are subtle but meaningful.

Head-to-head comparison

Code structure

Windsurf

Cursor

Generates larger components with mixed concerns. Clear project structure but individual files can be bloated. Sometimes over-uses client-side state.

Windsurf

Produces more modular, well-structured multi-file projects. Better separation of concerns. But interactions between files can introduce subtle bugs.

Bug types

Tie

Cursor

Bugs are usually obvious — unhandled errors, missing edge cases, improper state management. Easy to find during testing.

Windsurf

Bugs are more subtle — type mismatches between frontend and backend, auth middleware with logical gaps, circular dependencies. Harder to catch in testing.

Security

Tie

Cursor

Missing auth on routes, secrets in NEXT_PUBLIC_, string interpolation in queries. Standard AI security issues.

Windsurf

Auth middleware that looks correct but has bypass routes. SQL queries that sometimes use string concatenation. Error messages that leak internals. More deceptive issues.

Database patterns

Tie

Cursor

Decent ORM usage. Sometimes generates unnecessary queries but generally follows good patterns.

Windsurf

Better database architecture but prone to N+1 queries — generates a query per item in a list instead of batching. Missing indexes on commonly queried columns.

Error handling

Tie

Cursor

Inconsistent — some paths handle errors well, others show raw errors. Error boundaries often missing.

Windsurf

More consistent error handling overall, but error messages in production can leak stack traces and internal structure.

Developer experience

Cursor

Cursor

Larger community, more extensions, more tutorials. Agent mode is well-documented and powerful.

Windsurf

Strong 'Cascade' agent mode. Good codebase understanding. Smaller community but growing. Free tier is generous.

Code quality

Very close in overall quality. Windsurf produces slightly better-structured code with cleaner file organization. Cursor produces code that's easier to debug because issues are more visible. Windsurf's bugs are more subtle, which can be worse — they're harder to find and more likely to reach production. Both are strong choices for developer-focused AI coding.

Security

Both have security gaps, but they manifest differently. Cursor's gaps are straightforward — missing auth middleware, exposed env vars. Windsurf's gaps are trickier — auth middleware that has logical bypass routes, queries that look safe but occasionally use string concatenation. Both need thorough security review.

Which should you choose?

Choose Cursor if...

Developers who want a large ecosystem, robust agent features, and a well-documented tool. Best if you're already in the VS Code ecosystem.

Cursor services

Choose Windsurf if...

Developers who value clean code structure and want strong agentic capabilities. Best if you want a generous free tier or prefer Windsurf's agent workflow.

The bottom line

Both produce good code. Choose based on workflow preference and pricing rather than code quality — the differences are marginal. Either way, review the generated code for security and subtle bugs before production.

Frequently asked questions

Is Windsurf really free?

Windsurf has a generous free tier with a limited number of AI interactions per month. For professional use, you'll likely need a paid plan. Cursor also offers a free tier with limitations. Compare the current pricing on both websites — plans change frequently.

Can I switch between them easily?

Yes — both are VS Code forks, so your project works in either. Settings and extensions may not transfer perfectly, but your code is fully portable. Some developers even switch between them depending on the task.
