GitHub Copilot vs. Cursor vs. Windsurf

GitHub Copilot, Cursor, and Windsurf take completely different approaches to AI-powered coding. Each one changes how you write code in its own way.

GitHub Copilot started the whole AI coding movement. Microsoft built it to work inside the tools you already use. Now it can actually take over entire coding tasks and finish them for you.

Cursor built a brand new code editor from scratch. Everything about it revolves around AI. It doesn't just help you code - it becomes your coding partner.

Windsurf created something they call "AI flows." It's like having an AI that can read your mind while you code. The AI and you work together so smoothly it feels magical.

This guide will show you exactly how these three platforms differ, what each one does best, and which one fits your coding style.

What is GitHub Copilot?

GitHub Copilot turns your regular code editor into an AI powerhouse. It can suggest code as you type or take over entire projects.

Microsoft launched Copilot in 2021. Since then, they've added "agent mode," which lets Copilot grab a GitHub issue, determine what needs to be done, write all the code, test it, and create a pull request. You don't have to babysit it.

You can choose from different AI brains depending on your needs. Use Claude 3.7 Sonnet for quick stuff, or OpenAI o1 when you need serious thinking power. Copilot integrates with your repositories and understands your entire project, not just the file you're working on.

What is Cursor?

Cursor threw out the old way of building code editors. They designed everything around working with AI from day one.

The Anysphere team built Cursor because they thought AI should change everything about coding, not just add suggestions. Cursor has its own AI models trained specifically on code. This means it understands programming better than general AI tools.

Cursor Tab predicts what you want to write next - sometimes entire functions. The Agent mode can tackle a large task, break it down, write code across multiple files, run terminal commands, and automatically fix errors. You stay in control but don't have to do all the grunt work.

What is Windsurf?

Windsurf invented something called "AI flows" through their Cascade system. It creates a connection between you and AI that feels like mind-reading.

Codeium built Windsurf to solve a problem: most AI tools either help you a little bit or take over completely. Windsurf's Cascade system does both simultaneously. The AI works independently but stays perfectly synced with what you're thinking and doing.

Windsurf uses a special search system called Riptide that can scan millions of lines of code in seconds. You can see your website live inside the editor, click on any part, and tell the AI to change it. When you're ready, you deploy with one click.

GitHub Copilot vs. Cursor vs. Windsurf: detailed comparison

Picking the right AI coding tool affects how fast you code and how much you enjoy it. Here's how they compare:

Agent Capabilities

The better your AI works on its own, the bigger projects it can tackle without your help.

GitHub Copilot takes over your issues. You assign it a GitHub issue, and it plans everything out, writes the code, runs tests, and creates a pull request ready for review. It connects to your repository data and works like a new team member who already knows your project. You can comment to guide it or jump in to polish the code.

Cursor finishes tasks from start to end. Its Agent mode finds the right parts of your code, writes terminal commands and runs them, and fixes errors automatically. When it suggests code changes in chat, those changes appear in your files almost instantly. The custom models understand your specific way of coding.

Windsurf creates perfect teamwork. Cascade keeps you and the AI on exactly the same page every second. It watches what you do, understands what you want, and makes changes across multiple files while you work. This creates a feeling like the AI can read your thoughts and act on them.

Code completion

Good code suggestions make AI feel like a natural part of typing code.

GitHub Copilot shows you what comes next. It suggests edits that ripple across your whole project, keeping everything consistent. You can switch between different AI models - use fast ones for simple stuff, smart ones for hard problems. It even reviews your code automatically and catches bugs before humans see them.

Cursor Tab knows what you want to write. It suggests whole blocks of code based on what you just changed. If you make a mistake while typing, it fixes it automatically. Tab jumps you between related edits across different files, so you never lose context.

Windsurf gives you unlimited suggestions. You get unlimited fast completions plus access to premium AI models. It uses special software engineering models that understand coding better than general AI. The suggestions always fit with your project's structure.

Context understanding

AI that understands your whole project gives much better suggestions than AI that only sees one file.

GitHub Copilot plugs into everything. It connects to your repository data and outside services, so it understands your code structure, old pull requests, and current issues. Being built into GitHub means it knows more about your project than just the code.

Cursor sees your entire codebase. Its custom models understand complex projects without you having to explain anything. You can reference specific files, documentation, or web searches using @ symbols. You can even drag images into chat for visual context.

Windsurf achieves mind-reading levels. Cascade understands massive codebases and still gives relevant suggestions. It watches everything you do and compresses that information into a stream of understanding between you and the AI. Its Riptide technology scans millions of lines in seconds with better accuracy than other tools.

Model selection

Different AI models are good at different things. Having options lets you match the right intelligence to each task.

GitHub Copilot offers lots of premium models. Pick from Claude 3.7 Sonnet, OpenAI o1, Google Gemini 2.0 Flash, and more. The expensive plan gets you cutting-edge models like Claude Opus 4. Use fast models for routine work, smart models for complex thinking.

Cursor mixes custom and regular models. It built its own models specifically for coding tasks like Tab completion and Agent mode. These custom models understand programming patterns better than general AI. Regular API models handle chat conversations.

Windsurf introduces coding-specific models. The SWE-1 family focuses entirely on software engineering. You get unlimited access to SWE-1 Lite for everyday tasks, plus the full SWE-1 model for complex challenges. It also offers premium models like o3 at good rates.

Development workflow

The easier it is to use AI throughout your development cycle, the more productive you become.

GitHub Copilot works with your existing setup. Since it's built into GitHub, the AI helps with issues, pull requests, and code reviews - not just writing code. It adds autonomous features to your current workflow without forcing you to change anything.

Cursor becomes your new coding environment. The whole editor treats AI as essential, not extra. Press ⌘K to edit code with AI, generate terminal commands in plain English, and ask quick questions about any code. It learns how you work and adapts to match.

Windsurf lets you see and deploy instantly. You get live website previews inside the editor. Click any element and tell the AI to change it. When you're ready, deploy your app with one click. You never have to switch between different tools.

Pricing

Understanding costs helps you pick an AI assistant that fits your budget and delivers good value.

GitHub Copilot keeps pricing simple. Free gets you 50 AI requests per month. Pro costs $10/month with unlimited everything. Pro+ costs $39/month for access to the most advanced models. No surprises or hidden costs.

Cursor offers flexible options. You get a two-week trial to test everything. Pro costs $20/month for unlimited usage. Ultra costs $200/month with 20x more usage of premium models. Team plans cost $40/user/month and add business features.

Windsurf competes on value. Free includes 25 credits monthly. Pro costs $15/month with 500 credits. Teams cost $30/user/month with collaboration features. Enterprise starts at $60/user/month for big companies. Credits give you predictable costs.

Privacy and security

Code security matters for professional work. You need to know your intellectual property stays safe.

GitHub Copilot uses Microsoft's security. Your code gets enterprise-grade protection during processing. Business plans include legal protection if someone claims copyright issues. Organizations get policy management and access controls.

Cursor emphasizes privacy control. Privacy mode keeps your code on your machine only - it never gets sent anywhere or used for training. You control exactly what data gets collected. SOC 2 certification covers enterprise customers.

Windsurf offers flexible data protection. Zero data retention means your code doesn't get stored or used for training. Team plans get automated privacy protection. Enterprise customers get hybrid deployment options for extra security.

Final thoughts

Choose GitHub Copilot if you already use GitHub and want AI that integrates perfectly with your workflow. The agent mode and multiple AI models make it perfect for teams who want autonomous coding without changing their current setup.

Pick Cursor if you want the most advanced AI coding experience available. The custom models and AI-native editor are ideal if you're willing to learn a new tool to get the best AI assistance.

Select Windsurf if you want to experience the future of AI-human collaboration. The AI flows and innovative features like live previews are perfect for developers who want cutting-edge capabilities with smooth teamwork.
