GitHub Copilot vs Cursor vs Windsurf: Which AI Code Editor Should You Use?
Last updated: February 2026
Three AI-powered code editors. Three different price points. All promising to make you faster. But after using all three on real projects for the past two months, I can tell you they’re not even playing the same game.
Here’s the breakdown — no fluff, no sponsored takes.
Quick Answer
- GitHub Copilot ($10/mo): Best if you just want solid autocomplete and don’t want to switch editors
- Cursor ($20/mo): Best if you want the most polished AI-native coding experience
- Windsurf ($15/mo): Best if you want Cursor-like features but cheaper, and don’t mind some rough edges
Now let me explain why.
The Autocomplete Test
I wrote the same feature — a REST API with auth, rate limiting, and database queries — in all three editors. Timed how much the AI actually helped vs got in the way.
Copilot: Reliable. Predictable. The suggestions are conservative — it won’t try to write your entire function, but what it suggests is usually correct. Felt like a competent autocomplete that occasionally reads your mind.
Cursor: Aggressive in the best way. Tab completion doesn’t just finish your line — it predicts the next 5-10 lines based on context. When it’s right (which is ~75% of the time), it’s magical. When it’s wrong, you just hit Escape and move on.
Windsurf: Somewhere in between. The completions are good but slightly less context-aware than Cursor. I noticed it repeating patterns more often — like suggesting the same error handling block even when the context called for something different.
Winner: Cursor, but Copilot is the safest bet.
Agent Mode (The Real Differentiator)
This is where the gap widens. Agent mode = the AI can make multi-file changes, run commands, and iterate on its own work.
Copilot Agent: Exists now, but feels bolted on. It can make multi-file edits through the chat panel, but context management is weak. On a project with 200+ files, it frequently lost track of what it was doing. Microsoft is clearly investing here, but it’s not there yet.
Cursor Composer: The gold standard for in-editor agent mode. You describe a task, it plans the changes, shows you a diff, and applies them. It handles 5-10 file changes reliably. Beyond that, quality drops — but for most tasks, 5-10 files is enough.
Windsurf Cascade: Surprisingly capable. The “flows” concept — where it chains multiple actions together — works well for structured tasks. It sometimes outperforms Cursor on step-by-step tasks (like “add auth to every API route”). But it’s less reliable on ambiguous, open-ended requests.
Winner: Cursor, with Windsurf as a strong second.
The Context Problem
How much of your codebase can the AI actually understand at once? This matters more than people think.
Copilot: Relies heavily on the current file + a few related files. It uses @workspace to search broader context, but the results feel shallow. It knows what’s in your file. It vaguely knows what’s in nearby files. It doesn’t really “get” your project architecture.
Cursor: Better. The .cursorrules file lets you feed it project-specific context. The @codebase feature indexes your entire repo. In practice, it understands project structure reasonably well for repos under ~500 files.
Windsurf: Similar to Cursor in theory, but I found the context retrieval less reliable. It would sometimes miss obvious connections between files — like not realizing a type definition in types.ts was used in the file it was editing.
Winner: Cursor, though none of them are great at truly large codebases (for that, use Claude Code or Aider).
Pricing Reality Check
| Monthly Cost | What You Get | Hidden Costs | |
|---|---|---|---|
| Copilot | $10 | Unlimited completions, limited agent | None — flat rate |
| Cursor | $20 | 500 fast requests, unlimited slow | Fast requests run out mid-month if you’re heavy |
| Windsurf | $15 | Similar to Cursor’s tier | Credit system can be confusing |
Copilot is the clear value winner at $10/mo. If budget matters and you just want good autocomplete, it’s hard to argue against it.
Cursor at $20/mo is worth it if you use Composer/agent mode regularly. The 500 fast requests feel limiting for power users — you’ll either learn to be efficient with them or end up on slow mode by week 3.
Windsurf at $15/mo is the middle ground. You get most of Cursor’s features for 25% less. Whether the quality gap is worth $5/mo depends on how much you rely on agent mode.
Stability and Polish
Copilot: Rock solid. It’s backed by Microsoft/GitHub, runs inside regular VS Code, and rarely crashes or acts weird. Updates are incremental and non-disruptive.
Cursor: Mostly stable, but I’ve hit occasional jank — slow startup times, the AI panel freezing, indexing taking forever on large repos. Nothing deal-breaking, but you feel the “startup energy” in both good and bad ways.
Windsurf: The least polished of the three. I experienced more UI glitches, occasional crashes when Cascade was running complex flows, and the settings/configuration UX needs work. It’s improving fast, but it’s clearly the youngest product.
Winner: Copilot for stability. Cursor for overall polish.
Who Should Use What
Use GitHub Copilot if:
- Your company already pays for it
- You want zero disruption to your VS Code setup
- Autocomplete is your main need
- You’re on a budget
Use Cursor if:
- You want the best overall AI coding experience available today
- You use agent/composer mode for multi-file tasks
- You’re willing to pay $20/mo and learn its quirks
- You want to use multiple AI models (Claude, GPT-4, etc.)
Use Windsurf if:
- You want Cursor-like features at a lower price
- You do a lot of structured, step-by-step coding tasks
- You’re okay with some rough edges
- You want to bet on an underdog that’s improving fast
My Honest Recommendation
If you’re reading this and haven’t tried any of them: start with Cursor’s free trial. It’ll show you what AI-native coding feels like. If you love it, stay. If $20/mo feels steep for what you’re getting, try Windsurf. If you just want something that works without thinking about it, Copilot is always there.
I personally use Cursor as my daily driver and keep Copilot active as a fallback. Windsurf I check in on every few months — it’s the one most likely to surprise us all in a year.
