I switched between Cursor and GitHub Copilot as my only AI coding assistant for 30 days each. Here's the honest comparison.

My Setup

• Stack: TypeScript, React, Node.js, PostgreSQL
• Project: SaaS app with ~15K lines of code
• Measured: completions accepted, time saved, errors introduced

Bottom Line First

• Use Cursor if you want the most powerful AI coding experience and can pay $20/mo
• Use Copilot if you're on JetBrains or need enterprise features at $10/mo

Round 1: Autocomplete Quality

Both use frontier models (Cursor uses Claude/GPT-4, Copilot uses GPT-4).

Cursor wins here. The context window is larger — it reads more of your codebase before suggesting completions. I noticed it correctly inferring function signatures from files I hadn't even opened.

Copilot's suggestions are excellent for boilerplate but drift on complex business logic.

Acceptance rate in my testing:

• Cursor: 68% of suggestions accepted
• Copilot: 52% of suggestions accepted

Round 2: Multi-File Editing

This is where Cursor pulls way ahead.

Cursor's Composer lets you describe a feature in natural language and it edits multiple files simultaneously:

"Add rate limiting to all API routes using the existing Redis client"

Cursor opened 8 files, made coherent changes across all of them, and it worked first try.

Copilot has no equivalent. You're limited to single-file suggestions or chat-based assistance.

Round 3: Codebase Understanding

Cursor indexes your entire codebase and answers questions about it:

• "Where is the authentication middleware applied?"
• "What does the UserService.create() method return?"
• "Find all places where we directly query the database instead of using the ORM"

Copilot Chat can do some of this but it's slower and less accurate on large codebases.

Round 4: IDE Support

Copilot wins this round.

Cursor is VS Code only (it's a VS Code fork). Copilot works in:

• VS Code
• JetBrains (IntelliJ, WebStorm, PyCharm, etc.)
• Neovim
• Visual Studio

If you're on JetBrains, Copilot is your only real option.

Pricing

Time Saved (My Measurement)

I tracked time on similar feature implementations:

• Cursor: ~2.1 hours saved per feature
• Copilot: ~1.4 hours saved per feature

Over 30 days of daily coding, that's a significant difference.

My Recommendation

For solo developers on VS Code: Cursor ($20/mo) — the Composer feature alone is worth the extra $10 over Copilot.

For teams on JetBrains: Copilot — no choice, and it's still excellent.

For students/hobbyists: Copilot free tier through GitHub Education, or Cursor free tier.

Cursor: 9.2/10 | GitHub Copilot: 8.8/10
