AI Coding Assistants Comparison: WindSurf Editor vs. Cursor AI

The world of software development is buzzing with the transformative power of Artificial Intelligence. AI-powered coding assistants are no longer a futuristic dream but a present-day reality, promising to boost productivity, streamline workflows, and even help tackle complex coding challenges. Among the front-runners in this domain are two noteworthy Integrated Development Environments (IDEs): WindSurf Editor and Cursor AI. Both offer compelling AI capabilities, but they come with different philosophies and feature sets.

This blog post dives deep into a comparison of WindSurf Editor (formerly Codeium) and Cursor AI, exploring their key features, strengths, weaknesses, and ideal use cases to help you decide which AI co-pilot might be the perfect fit for your coding adventures in 2025.

Meet the Contenders: WindSurf Editor and Cursor AI

WindSurf Editor: The Agentic IDE Riding the Wave of AI Flows

WindSurf Editor, which evolved from Codeium, positions itself as the first “agentic IDE.” It’s built around the concept of “Flows,” aiming to create a seamless synergy between the developer and AI, where the AI acts as both a collaborative Copilot and an autonomous Agent.

Key Features of WindSurf Editor:

• Cascade: This is WindSurf’s core AI engine, offering:
  • Agentic Coding: Can understand intent and autonomously work on tasks across multiple files, including running commands and debugging.
  • Multiple Modes: Includes a “Write” mode for more autonomous generation and a “Chat” mode for interactive assistance.
  • Multi-file Editing & Contextual Awareness: Deeply understands your codebase structure and can make coherent changes across various files.
  • Terminal Integration: Generate and run terminal commands using natural language.
  • Image Upload: Generate HTML, CSS, and JavaScript from uploaded images of website designs.
• Supercomplete: An advanced autocompletion feature that predicts intent beyond just the next line of code, capable of generating entire functions with docstrings.
• Inline AI (Cmd+I): Make changes to specific code blocks, generate docstrings, or refactor sections without affecting the rest of the codebase.
• Local and Remote Indexing: Creates an index of your codebase for enhanced context awareness. Local indexing keeps your code private, while remote indexing is available for teams.
• Memories: Allows the AI to retain context across conversations for continuity.
• AI Rules: Define custom rules for Cascade to follow, such as coding language, framework, or API usage.
• Windsurf Previews: See live previews of your web application within the IDE and even deploy directly, minimizing context switching.
• Linter Integration: Automatically fixes linter errors in AI-generated code.

Cursor AI: The VS Code Fork with Powerful AI Enhancements

Cursor AI is an AI-first code editor built as a fork of the popular Visual Studio Code (VS Code). This foundation means it offers a familiar environment for many developers while layering powerful, natively integrated AI functionalities.

Key Features of Cursor AI:

• Agent Mode: Can take on tasks end-to-end, finding context within the codebase, running terminal commands (with confirmation), and looping on errors to fix them.
• Tab Autocompletion: A robust autocomplete feature that predicts and suggests multi-line edits, and can even perform smart rewrites as you type.
• AI Chat: A versatile chat interface with deep codebase awareness:
  • Contextual Understanding: Sees your current file and cursor position.
  • @ Mentions: Easily reference files (@file), symbols, your entire codebase (@Codebase), fetch information from the web (@Web), or specific documentation (@Docs).
  • Image Input: Include images in your chat prompts for visual context.
  • Instant Apply: Directly apply code suggestions from chat into your codebase.
• Ctrl+K (or Cmd+K): Allows for inline code generation or editing. Select code and describe changes, or generate new code from a natural language prompt. Also works in the terminal.
• VS Code Compatibility: Seamlessly integrates with existing VS Code extensions, settings, and keybindings.
• Codebase Indexing: Indexes your entire project for comprehensive understanding and relevant answers.
• Custom Rules (.cursorrules): Guide the AI’s behavior and style.
• Privacy Mode: Offers options where code is not stored remotely.

AI Model Access: Quality Over Quantity

Both IDEs give you access to top-tier models like GPT-4, Claude 3.5 Sonnet, and more. Cursor also includes experimental models like 01 Mini and 01 Preview, which can be nice for niche use cases.

However, when you’re on the free tier, the quality of outputs really matters — and WindSurf’s Cascada Base model outperforms Cursor Small by a noticeable margin. Code suggestions are more reliable, more accurate, and overall just feel more aligned with what I want as a developer.

Head-to-Head: WindSurf Editor vs. Cursor AI

Let’s compare these two AI coding powerhouses across several key aspects:

1. User Interface (UI) & Ease of Use:

• WindSurf Editor: Often praised for a more intuitive UI, especially for beginners. Its “Cascade” feature, with distinct “Write” and “Chat” modes and a step-by-step workflow, is considered user-friendly.
• Cursor AI: Leverages the familiar VS Code interface, which is a significant advantage for developers already accustomed to it. However, some users have noted that the interface can occasionally feel cluttered with AI-specific buttons and popups.

2. Core AI Capabilities & Approach:

• WindSurf Editor: Emphasizes its “agentic” approach with “Flows,” aiming for a proactive AI that deeply understands context and collaborates in real-time. Cascade is central to this, designed to handle complex tasks and multi-file operations more autonomously.
• Cursor AI: Provides a suite of powerful AI tools, including a capable Agent mode, advanced chat functionalities with diverse context integration (codebase, web, docs), and strong inline editing. It’s designed to augment the VS Code experience with robust AI.

3. Context Handling:

• WindSurf Editor: Features automatic codebase analysis for context and utilizes local (or remote for enterprise) indexing for comprehensive codebase awareness. Users have reported its context handling to be quite automatic.
• Cursor AI: Allows for more manual and explicit context management through “@” mentions, selecting code blocks (Ctrl+Shift+L), and project-wide indexing. The .cursorrules file also provides a way to guide AI context.

4. Code Quality & Generation:

• Both tools utilize powerful underlying Large Language Models (LLMs), so the baseline quality of generated code can be comparable.
• Some anecdotal comparisons suggest that in specific tasks, like cloning an entire application, Cursor AI produced more complete results with fewer initial errors. However, both are capable of sophisticated multi-file edits and complex code generation.

5. Standout Features:

• WindSurf Editor:
  • Cascade’s modes (Write, Chat, Legacy): Offers flexibility in how you interact with the AI.
  • Image-to-code generation: A unique feature for quickly scaffolding front-end components from visual designs.
  • Windsurf Previews: Integrated live preview and deployment significantly streamline the web development workflow.
  • Proactive agentic behavior: Aims to anticipate developer needs.
• Cursor AI:
  • Solid VS Code foundation: Access to the vast VS Code extension marketplace and familiar workflows.
  • Rich Chat integrations (@Web, @Docs): Powerful for research and using up-to-date information or library documentation directly within the IDE.
  • Detailed context control with .cursorrules: Offers fine-grained customization of AI behavior.

6. Learning Curve:

• WindSurf Editor: Generally considered to have a gentler learning curve for beginners due to its intuitive UI and more guided agent features.
• Cursor AI: Very easy to pick up for existing VS Code users. For those new to the VS Code environment, there might be a slightly steeper curve, though the core AI features are designed to be accessible.

7. Pricing (based on information from early 2025):

• Free Tiers: Both WindSurf and Cursor offer free tiers, which typically provide access to premium models but at a slower speed or with usage limits.
• Pro Plans:
  • WindSurf Pro: Was reported around $15 per month, offering a set number of fast premium model requests (e.g., 500).
  • Cursor Pro: Was reported around $20 per month, also offering a similar quota of fast premium model requests.
  • Disclaimer: Pricing in the AI space is dynamic. WindSurf mentioned a pricing update in April 2025, so it’s crucial to check their official websites for the latest information.
