Cursor vs Windsurf —
AI Code Editor Showdown, Tested Side by Side
Two VS Code forks, both promising AI-powered coding superpowers. We used both daily for four weeks on the same projects to see where each one actually delivers — and where the marketing falls apart.
Key Takeaways:
- • Cursor ($20/mo) has stronger multi-file editing and a more mature agent mode (Composer). It handles large refactoring tasks across 5+ files without losing context
- • Windsurf ($15/mo) costs less and offers a smoother inline completion experience. Its Cascade mode is fast for single-file tasks but struggles with complex cross-file operations
- • Both are VS Code forks — your extensions, themes, and keybindings transfer. Switching between them takes about 5 minutes
- • Pick Cursor if you do heavy refactoring or work on large codebases. Pick Windsurf if budget matters and you mostly work in single files
How We Tested
We ran both editors on identical projects for four weeks: a Next.js 16 app with around 200 files, a Python FastAPI backend, and a React Native mobile app. Same developer, same tasks, alternating which editor went first to reduce bias.
- • Completions test: 100 identical prompts across TypeScript, Python, and Go
- • Agent test: 20 multi-file refactoring tasks (rename, extract component, add feature)
- • Speed test: Time-to-first-token and completion latency measured with timestamps
- • Versions: Cursor 0.48 (Pro) vs Windsurf 1.9 (Pro), both using Claude Sonnet 4.5 as default model

AI Completion Quality: Cursor Edges Ahead
We fed both editors 100 identical coding prompts across TypeScript, Python, and Go. Cursor produced usable completions about 78% of the time on the first attempt. Windsurf landed at around 71%. Not a massive gap, but it compounds over a full day of coding.
Where Cursor really pulled ahead was context awareness. When working in a Next.js project with custom hooks and shared types, Cursor's completions correctly referenced project-specific patterns more often. Windsurf tended to suggest more generic solutions — technically correct but requiring manual adjustment to match the codebase style.
Windsurf's inline completions felt snappier, though. The time-to-first-token was roughly 200ms faster on average, which makes the typing flow feel more natural. If you're the kind of developer who tabs through completions rapidly, Windsurf's speed advantage matters more than Cursor's accuracy edge.
Agent Mode: Composer vs Cascade
Both editors ship an "agent mode" that can plan and execute multi-step coding tasks. Cursor calls it Composer. Windsurf calls it Cascade. They work differently under the hood and the results vary quite a bit.
Cursor's Composer operates more like a project-aware assistant. You describe what you want ("add dark mode to this component with a toggle in the header"), and it creates a plan showing which files it will touch, then executes the changes. You review diffs before accepting. The planning step catches many errors before they happen.
Windsurf's Cascade takes a different approach — it streams changes in real time as it thinks. Feels faster because you see progress immediately. The downside is that it sometimes commits to a wrong approach early and digs deeper into it rather than stepping back. We had to undo and retry about 30% more often with Cascade compared to Composer.
Verdict: Composer's plan-then-execute approach produces more reliable results. Cascade feels faster but wastes time on retries.
Multi-File Editing: The Deciding Factor for Large Projects
This is where Cursor justifies the extra $5/month. We tested 20 refactoring tasks that touched multiple files: renaming a shared interface, extracting a component into its own module, adding a new API endpoint with types and tests.
Cursor handled tasks touching 5-8 files without losing coherence. Import paths stayed correct, type definitions propagated properly, and test files got updated alongside implementation changes. Not perfect — it occasionally missed a barrel export — but workable.
Windsurf started showing cracks past 3-4 files. A rename refactor that should have updated 6 files would often miss 1-2 of them. Import statements were the usual casualty. We spent more time fixing Windsurf's multi-file output than we saved by using the AI in the first place on some tasks.
Terminal Integration
Both editors embed a terminal with AI awareness. You can ask either to run commands, read terminal output, and adjust code based on error messages. Cursor reads build errors and suggests fixes inline. Windsurf does the same but adds a "Fix in Cascade" button that feeds the error directly into its agent mode.
Windsurf's terminal-to-Cascade pipeline is actually smoother here. Click the button, Cascade reads the error and the relevant file, proposes a fix. Cursor requires you to copy the error into the chat panel or highlight it manually. Small friction, but it adds up across dozens of debug cycles.
Pricing: $5 Difference, Different Value Propositions
Cursor Pro runs about $20/month. Windsurf Pro about $15/month. Both offer free tiers — Windsurf's is more generous with roughly 50 daily completions versus Cursor's 30. For teams, the gap widens: Cursor Business at $40/seat versus Windsurf Team at $30/seat.
The $5/month individual difference is negligible for working developers. The $10/seat/month team difference is not — a 10-person team saves $1,200/year with Windsurf. Whether the team features justify Cursor's premium depends on how much multi-file refactoring your team does daily.
The Honest Downsides
Cursor Problems
- • Composer can be slow on large codebases — the planning step sometimes takes 15-20 seconds
- • Extension conflicts with some popular VS Code plugins (GitLens occasionally misbehaves)
- • The $20/mo price puts it at the upper end for individual developers
- • Memory usage creeps up — expect 2-3 GB RAM with a medium project open
Windsurf Problems
- • Multi-file editing above 3-4 files is unreliable
- • Cascade sometimes confidently applies wrong fixes that break other files
- • Fewer extension compatibility (about 92% vs Cursor's 95%)
- • Documentation is thinner — you'll rely on community Discord for troubleshooting
Frequently Asked Questions
Is Cursor or Windsurf better for multi-file editing?▼
Cursor currently handles multi-file edits more reliably. Its Composer feature can modify 5-8 files in a single operation with decent accuracy. Windsurf's Cascade mode attempts similar cross-file changes but occasionally loses track of imports or type definitions when touching more than 3-4 files simultaneously. For large refactoring jobs, Cursor is the safer pick.
Can I use my own API key with Cursor or Windsurf?▼
Both editors support bring-your-own-key setups. Cursor lets you plug in OpenAI, Anthropic, or Azure keys through its settings panel. Windsurf supports OpenAI and Anthropic keys as well. Using your own key can reduce costs if you have existing API credits, but you lose access to the editors' optimized routing and caching — so responses may actually feel slower.
Which AI code editor is cheaper, Cursor or Windsurf?▼
Windsurf Pro costs around $15/month compared to Cursor Pro at roughly $20/month. Both offer free tiers with limited completions. Windsurf gives you more completions on the free plan (about 50/day vs Cursor's 30), making it the better option if you want to try before committing. For teams, Cursor charges $40/seat/month for Business while Windsurf charges $30/seat/month.
Does Windsurf work with VS Code extensions?▼
Windsurf is built on a VS Code fork, so most VS Code extensions work out of the box. Same for Cursor — it's also a VS Code fork. In practice, about 90-95% of extensions transfer directly. The exceptions tend to be extensions that deeply modify the editor UI or conflict with the AI features. Both editors maintain their own marketplace alongside VS Code compatibility.

Our Verdict: Which AI Code Editor Deserves Your Money?
Cursor is the stronger editor for professional developers working on complex, multi-file projects. The Composer agent handles refactoring tasks that Windsurf can't match yet. Windsurf is the smarter budget pick — $5/mo cheaper, faster inline completions, and a more generous free tier.
For solo devs on smaller projects: Windsurf. For teams doing heavy refactoring: Cursor. Both are dramatically better than vanilla VS Code with Copilot for agentic coding tasks.
