Quick Verdict

Cursor and Windsurf are both full VS Code forks built around AI-first editing rather than a plugin bolted onto a standard editor. Cursor's Composer feature is the strongest multi-file editing experience of the two, showing a clear diff across every file it touches before you accept anything. Windsurf's Cascade agent leans toward staying in what its team calls a flow state, making more changes with less interruption. Neither is a clear universal winner; the right pick depends on how much you want to review before code lands.

Pros

  • ✅ Cursor's Composer shows a clear multi-file diff before changes land
  • ✅ Windsurf's Cascade agent makes longer autonomous changes with less back-and-forth
  • ✅ Both run local terminal commands as part of agent actions

Cons

  • ❌ Both require moving off stock VS Code, including reinstalling extensions
  • ❌ Team seat pricing adds up quickly for larger engineering orgs

What Each Editor Does

Cursor is a VS Code fork with an AI layer built around its Composer feature, which can plan and execute changes across multiple files while showing you a reviewable diff before anything is applied. It's built for developers who want strong agentic capability but still want a clear approval step before code changes stick.

Windsurf, built by the team behind Codeium, takes a similar fork-of-VS-Code approach but centers its agent, Cascade, around minimizing interruption. It's designed to keep you in what the team describes as flow state, making broader changes with less step-by-step confirmation, which some developers find faster and others find riskier.

How we tested it

We ran the same task through both editors in June 2026: adding a new authentication flow to a mid-sized Next.js app, touching an API route, a client-side form, and a shared types file. In Cursor, Composer laid out its plan first, listing the files it intended to touch, then produced a diff for each one that we could accept, edit, or reject individually. It got the types file right on the first pass and needed one follow-up prompt to fix an import path in the API route.

Windsurf's Cascade took a more end-to-end approach. Given the same prompt, it worked through all three files in one pass with far less back-and-forth, running a couple of terminal commands along the way to check the build. The result was correct, but reviewing it after the fact meant scanning a larger combined diff rather than approving smaller chunks as we went. Neither approach was clearly faster in wall-clock time; the difference was entirely in how much you watch versus how much you check afterward.

Where each one falls short

Cursor's step-by-step diff review is reassuring, but it also means more clicking through approval prompts on a task that touches many files, which can feel tedious on a large refactor. Its indexing of very large monorepos has also been inconsistent in our experience. Occasionally it missed a relevant file until we manually re-indexed the project, which isn't something you want to discover mid-task.

Windsurf's Cascade is fast and confident, sometimes too confident. Letting it run further before checking in raises the odds that you'll need to unwind a chunk of unwanted changes rather than catch a small mistake early. Its terminal command execution, while convenient, is also a bigger trust step: you're granting it more autonomy to run things on your machine than Cursor typically asks for in a single pass.

Which One Should You Use?

Solo developers and small teams who want to stay in tight control of every change, particularly on production codebases where a bad autonomous edit is costly, will prefer Cursor's checkpoint-by-checkpoint diff review. It's also the safer pick for anyone newer to AI-assisted coding who wants to build trust in the tool gradually rather than hand over a large task at once.

Developers doing a lot of scaffolding, prototyping, or greenfield work where speed matters more than line-by-line review tend to prefer Windsurf's Cascade, since it can carry a task further before needing input. Teams standardizing on one editor across the org should weigh the per-seat cost difference too: at scale, Windsurf's lower list price adds up, though Cursor's tighter review loop can mean fewer costly mistakes to unwind, which is its own kind of savings.

Frequently Asked Questions

Can I import my existing VS Code extensions and settings?

Yes, both editors support importing VS Code extensions and keybindings, which shortens the migration since you're not rebuilding your setup from scratch.

Which one is better for large codebases?

Both handle large codebases reasonably well, though results vary by language and project structure. Test the free tier on your actual codebase rather than relying on general benchmarks.

Do either of these replace GitHub Copilot?

They compete more directly with each other than with Copilot, since both are full editor forks rather than an extension. Copilot remains the simpler choice if you want to stay in stock VS Code.

Which one is cheaper for a team?

Windsurf is meaningfully cheaper on paper, roughly $10 less per user per month at both the individual and team tiers. Whether that gap matters depends on how much time Cursor's slower, more deliberate review process saves you in avoided mistakes, which is harder to put a number on.

Can I switch between them without losing my project setup?

Both are VS Code forks, so your project files, git history, and most extensions carry over cleanly. Editor-specific settings, like Cursor's Composer rules or Windsurf's Cascade preferences, don't transfer between them and need to be reconfigured.

Final Verdict

Cursor and Windsurf are close enough in capability that the deciding factor is workflow preference rather than raw quality. Try the free tier of each on a real task from your own codebase before committing a team to either one.
