Introduction
The AI code editor space has consolidated fast. Two names now dominate: Cursor and Windsurf (formerly CodeLlama by Codeium). Both are AI-first editors that aim to replace your existing IDE with one that has AI built into every interaction. But they take very different approaches — Cursor is a refined VS Code fork, while Windsurf is a from-scratch editor designed around agentic AI workflows.
We spent four weeks using both tools daily on real production codebases — from frontend React apps to Python data pipelines. This comparison covers installation, day-to-day coding, multi-file refactoring, pricing, privacy, and who should pick each tool.
What Is Cursor?
Cursor is a fork of VS Code that adds AI features natively. It was launched in 2023 and quickly became the most popular AI code editor. The core features include Cmd+K inline editing, Tab autocompletion, a chat panel that understands your codebase, and codebase-wide search. Because it's a VS Code fork, every extension, theme, and keyboard shortcut you use in VS Code works immediately.
The learning curve is essentially zero if you already use VS Code. Open a project, start typing, and the AI suggestions appear inline. The Pro plan costs $20/month and includes 500 premium requests plus unlimited basic requests per month.
What Is Windsurf?
Windsurf (formerly Codeium's IDE) is a from-scratch code editor built around agentic AI. Its signature feature is Cascade — an AI agent that can plan, reason, and execute multi-file changes in your codebase. Instead of asking the AI to edit one file at a time, you describe what you want done, and Cascade plans the changes, shows you the plan, and executes it across multiple files.
Windsurf also offers inline editing and chat, but the agent mode is the differentiator. The editor itself is Electron-based, so it feels snappy but doesn't have the same extension ecosystem as VS Code. Pricing is $20/month for Pro, same as Cursor.
Head-to-Head Comparison
Day-to-Day Coding
For writing new code file by file, Cursor feels more natural. The Tab autocompletion is faster and more accurate for single-file work. When I'm writing a React component from scratch, Cursor suggests the next few lines based on what I've already written, and it's usually correct. Windsurf's inline editing is good too, but the suggestions feel less seamless — there's more friction between typing and accepting a suggestion.
Winner: Cursor — faster inline suggestions, more natural typing flow.
Multi-File Refactoring
This is where Windsurf shines. When I needed to refactor an API call across 12 files to use a new endpoint, I described the change to Cascade, it planned the edits, showed me the plan, and executed them in under a minute. In Cursor, I would have had to manually apply the same change file by file, or use the chat panel to generate the changes and then apply them one at a time.
Cursor does have codebase-wide understanding, but it's more of a search-and-chat feature than an autonomous executor. Windsurf actually makes the changes for you.
Winner: Windsurf — Cascade handles multi-file changes that would take hours manually.
Extension Ecosystem
Cursor wins by a mile here. Because it's a VS Code fork, you can install any VS Code extension — ESLint, Prettier, GitLens, Docker, remote development, everything. Windsurf has its own extension store but it's much smaller. If you rely on niche VS Code extensions for your workflow, Cursor is the obvious choice.
Winner: Cursor — full VS Code extension compatibility.
Privacy and Security
Both tools offer privacy modes. Cursor's privacy mode keeps your code on your machine and doesn't send it to Cursor's servers. Windsurf offers enterprise plans with SSO and data residency options. For individual developers, both are fine. For regulated industries, Windsurf's enterprise features edge it slightly.
Winner: Tie — both offer solid privacy options.
Pricing
Both cost $20/month for Pro. Cursor includes 500 premium requests per month; Windsurf's Pro includes unlimited agentic runs. If you're a heavy agent user, Windsurf offers more value per dollar. If you mostly do inline editing, Cursor's request-based model is fine.
Winner: Windsurf — unlimited agent runs at the same price point.
Real-World Testing Results
We tested both tools on three scenarios:
Scenario 1: Build a landing page from scratch. Cursor was faster for writing individual components. The Tab autocomplete nailed common patterns like React hooks and Tailwind classes. Time: 25 minutes.
Scenario 2: Refactor authentication from JWT to OAuth. This involved changes across 8 files. Windsurf's Cascade planned the changes, showed the plan, and executed in 3 minutes. Cursor took 15 minutes of manual prompting and file-by-file editing.
Scenario 3: Debug a production issue. Both tools were equally helpful. The chat panel in both could read stack traces and suggest fixes. Cursor's codebase search was slightly better for finding where a function was defined.
