Cursor vs Windsurf: Which AI IDE Should You Use?

Cursor is the better AI IDE for most professional developers right now, though Windsurf has carved out a genuinely compelling niche for those who want a more guided, agentic coding experience at a lower price. Both tools fork VS Code and layer AI deeply into the editing workflow, but they take fundamentally different approaches to how much the AI should do versus how much you should steer. If you've been bouncing between tabs trying to figure out which one deserves your subscription, this is the breakdown that actually matters.

At-a-Glance Comparison

What Is Cursor?

Cursor launched in early 2023 as a fork of VS Code with AI woven into every interaction. Built by Anysphere, a San Francisco startup that raised $60 million in a Series A round reported by TechCrunch in 2024, the editor has quickly become the default recommendation in developer circles when someone asks about AI-assisted coding.

The pitch is straightforward: take the editor millions of developers already know, then embed AI so deeply that you rarely need to copy-paste code into a separate chat window. You get tab-completions that understand your entire codebase (not just the open file), inline chat that can edit code in place, and Composer — a multi-file editing agent that can scaffold features across dozens of files simultaneously.

What sets Cursor apart from slapping Copilot into VS Code is context awareness. It indexes your project, lets you @-mention specific files or documentation, and generates suggestions that actually reflect your architecture. It's not perfect. Large monorepos can still confuse it. But the gap between Cursor's contextual understanding and a generic LLM chat is enormous.

What Is Windsurf?

Windsurf (formerly Codeium) rebranded in late 2024, pivoting from a Copilot-style autocomplete tool into a full AI IDE. The rebrand wasn't cosmetic. Windsurf introduced Cascade, an agentic AI system that doesn't just suggest code — it plans, executes multi-step tasks, runs terminal commands, and iterates on errors autonomously.

Think of the difference this way: Cursor is a brilliant pair-programmer who waits for your instructions. Windsurf's Cascade is more like a junior developer you can hand a ticket to. You describe what you want ("add user authentication with OAuth2 and update the routes"), and Cascade will create files, install dependencies, write tests, and debug failures in a loop. It's genuinely impressive when it works. When it doesn't, you're debugging AI-generated code across files you didn't write, which can be disorienting.

Windsurf also retains its roots as a strong autocomplete engine. The base completions are fast and the free tier is more generous than Cursor's, which matters if you're a student or hobbyist.

Key Features: Where They Actually Differ

Cursor's Composer vs Windsurf's Cascade

This is the real battleground. Both tools offer chat-based AI assistance, but their flagship features represent different philosophies.

Cursor's Composer lets you describe a change and generates a multi-file diff. You review each change, accept or reject individual hunks, and maintain tight control. I used it recently to refactor a Next.js API layer across eight files. It proposed sensible changes, I rejected two that would have broken a downstream service, and the whole thing took about ten minutes instead of an hour. The key word is review. You stay in the driver's seat.

Windsurf's Cascade takes a more autonomous approach. You describe a goal, and it creates an execution plan, then works through it step by step. It can read your file tree, open a terminal, install packages, and loop back when something fails. For greenfield prototyping, this is borderline magical. I asked it to scaffold a basic Express API with Prisma and PostgreSQL, and it produced a working setup in under three minutes. The trade-off is that when Cascade makes a wrong architectural decision early in a chain, the subsequent steps compound the error. Rolling back requires more effort than with Cursor's granular diff approach.

Codebase context and indexing

Cursor's codebase indexing is more mature. It uses embeddings to understand your project structure and lets you @-reference files, folders, docs, and even web URLs in prompts. Windsurf indexes too, and Cascade is aware of your project, but the referencing system isn't as flexible. Cursor also supports .cursorrules files, which let you define project-specific instructions the AI always follows. This is a small feature that makes a big difference on team projects.

Model flexibility

Cursor gives you access to a wider range of models out of the box. GPT-4o, Claude 3.5 Sonnet, Claude 4 Sonnet, and Gemini models are all available on paid plans. You can also bring your own API key for OpenAI, Anthropic, or other providers, which is useful if your company already has an enterprise agreement. Windsurf offers GPT-4o and Claude Sonnet alongside its own proprietary models. The selection is narrower, and the BYOK (bring your own key) options are more limited.

Extensions and ecosystem

Both are VS Code forks, so both support the VS Code extension marketplace. Your keybindings, themes, and most extensions carry over. This is a genuine advantage over non-VS-Code AI IDEs. If you've spent years customising your VS Code setup, migration takes minutes, not days.

Is Cursor or Windsurf Better for Beginners?

Windsurf, without much hesitation. Cascade's agentic workflow means you can describe what you want in plain English and watch the AI build it. You learn by observing what it does — which files it creates, which packages it installs, how it structures things. It's like having a senior developer build something while you watch over their shoulder.

Cursor is more powerful but assumes you already know what you're doing. Its Composer generates diffs that require you to understand the codebase well enough to review them critically. The inline chat is brilliant if you know the right questions to ask. For someone learning to code, or a designer shipping their first side project, Windsurf's hand-holding approach is genuinely more useful.

That said, there's a risk with Windsurf's approach for learners. If Cascade does everything, you might not internalise the patterns. A few developers I know have started using Cursor specifically because they want to stay more engaged with the code. Your mileage will vary depending on how you learn best.

"I switched from Cursor to Windsurf for a hackathon project and shipped in half the time. But when I went back to my day job on a large Rails codebase, Cursor's Composer was way better at handling targeted refactors without breaking things." — Developer on r/programming

Which One Is Cheaper for a Solo Developer?

Windsurf is cheaper on paper. Its Pro plan starts at $15/month according to Windsurf's pricing page. Cursor's Pro plan is $20/month per Cursor's pricing page. Both offer free tiers, but the limits differ.

Cursor's free tier includes a limited number of premium model requests (slow completions after that). Windsurf's free tier historically offered more generous autocomplete usage, though the specifics shift frequently as both companies adjust limits. Check the pricing pages directly — these numbers change quarterly.

For teams, Cursor offers a Business plan at $40/user/month with centralised billing, admin controls, and enforced privacy mode. Windsurf has team-oriented plans too, but Cursor's enterprise features are more developed, partly because it had a head start in courting professional teams.

If you're freelancing in the UK and billing in pounds, the difference between £16 and £12 a month probably isn't your deciding factor. The real cost question is productivity: which tool saves you more billable hours? For complex project work, Cursor's precision tends to save more time. For rapid prototyping and MVPs, Windsurf's speed is hard to beat.

Final Verdict

Pick Cursor if you're a professional developer who works on established codebases, values precise control over AI-generated changes, and wants access to the broadest range of frontier models. It's the more mature product, the multi-file editing is best-in-class, and features like .cursorrules give it an edge on team projects. The $20/month is easy to justify if it saves you even an hour a week.

Pick Windsurf if you prioritise speed over control, build lots of greenfield projects, or want the AI to handle more of the execution autonomously. It's also the better entry point if you're newer to development, or if you're a designer/PM who codes on the side. At $15/month, it's the cheaper option, and Cascade's agentic approach is a genuine glimpse of where all IDEs are heading.

Neither is a bad choice. Both are dramatically better than using a vanilla editor with a chatbot in a separate window. The gap between these two and a plain VS Code + Copilot setup is real and growing.

Best for experienced developers and teams: Cursor.

Best for solo builders, prototyping, and beginners: Windsurf.

Avoid Cursor if: you want the AI to handle entire tasks end-to-end without much oversight.

Avoid Windsurf if: you need fine-grained diff review and the ability to reject individual changes in multi-file edits.
