Cursor vs GitHub Copilot: I Switched and Here's What Happened

The switch

I used GitHub Copilot for about 18 months. I was happy with it. It lived in VS Code, suggested code as I typed, and saved me from writing boilerplate. Simple, useful, done.

Then a friend showed me Cursor and said "just try it for a week." That was six months ago. I haven't gone back.

This isn't a "Cursor is perfect and Copilot is terrible" comparison. Both are excellent tools. But they're different in ways that matter, and after using both extensively, I have strong opinions about who should use which.

The fundamental difference

Copilot is an AI feature added to your existing editor. Cursor is an editor built around AI from the ground up.

This difference sounds subtle but it affects everything. Copilot adds AI suggestions to VS Code and that's mostly it. Cursor rethinks the entire editing experience with AI at the centre. Code completion, multi-file editing, codebase-aware chat, inline editing, and an agent mode that can plan and execute changes across your entire project.

It's the difference between a car with a GPS bolted on versus a car designed around the GPS from day one.

Inline completions

Both are good at this. You type, they suggest, you tab to accept. The quality of suggestions is comparable. Copilot might have a slight edge in speed (the suggestions appear fractionally faster) but the accuracy is similar enough that you wouldn't notice in blind testing.

Where Cursor pulls ahead is context awareness. It considers not just the file you're working in but your entire project. The suggestions feel more appropriate because Cursor understands the patterns, naming conventions, and architecture of your specific codebase.

Multi-file editing (Cursor's killer feature)

This is where the gap opens up dramatically. Cursor's Composer feature lets you describe a change in natural language and it'll plan and execute edits across multiple files simultaneously. "Add error handling to all the API routes" and it'll modify ten files in a coordinated way.

Copilot can't do this. It works on one file at a time. If you need to make coordinated changes across your codebase, you're doing each file manually.

For small projects, this doesn't matter much. For large codebases, Composer is worth the price of admission by itself. It's saved me hours on refactoring tasks that would have been tedious and error-prone to do by hand.

Chat features

Both have chat features that let you ask questions about your code. Cursor's chat is better because it has deeper awareness of your project. Ask "how does authentication work in this project?" and Cursor will actually look at your auth files and give you a specific answer. Copilot's chat tends to give more generic answers.

Cursor also lets you select code and ask the AI to modify it inline, with a diff preview before you accept the change. This workflow is fantastic for quick refactors and code improvements.

The editor experience

Cursor is a fork of VS Code, so it feels familiar immediately. Your extensions work, your keybindings carry over, and the settings transfer. The transition took me about two hours.

Copilot lives inside VS Code (or JetBrains, or Neovim, or basically any editor). If you're deeply committed to a specific editor, Copilot works with it. Cursor requires you to use Cursor.

This is Copilot's biggest advantage for some developers. If you've spent years customising your Neovim setup, you're not going to throw that away for a VS Code fork, no matter how good the AI is.

Pricing

Cursor is twice the price. For some developers, the multi-file editing and deeper codebase awareness justify the premium. For others, Copilot does enough at half the cost.

There's also Cursor's free tier, which gives you a limited number of completions and chat messages per month. It's enough to evaluate the tool but not enough for daily use.

Reliability and speed

Copilot is more reliable. It's been around longer, the infrastructure is more mature, and I've experienced fewer outages. Cursor occasionally has slow moments where completions take a second or two longer than expected, and the chat feature can be sluggish during peak hours.

Neither is unreliable. But if consistency matters to you (and it should), Copilot has the edge.
