There are more and more AI coding assistants on the market—how do you choose?
Comparison of the Three
| Dimension | Cursor | GitHub Copilot | Claude Code |
|---|---|---|---|
| Underlying Model | Multi-model | GPT-4o | Claude |
| Code Completion | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐ |
| Multi-file Editing | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐ |
| Context Understanding | ⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
| Price | $20/month | $10/month | Pay-as-you-go API |
Cursor
Like an AI with an IDE built in. Fastest completion, strongest multi-file refactoring.
# Cursor understands what you want
# Input: refactor this to use dataclass
# It directly modifies all files
Best for: Daily development, refactoring, writing new features.
Copilot
The most established option, with the most stable completion. Deepest integration with VS Code.
Best for: Writing boilerplate code, unit tests, doc comments.
Claude Code
More like an AI colleague. Excels at understanding complex requirements, debugging, and explaining code.
Best for: Debugging, code review, architecture discussions, writing technical documentation.
Practical Recommendations
- Daily development → Cursor
- Save money + VS Code → Copilot
- Complex problems → Claude Code (use as needed, it's not expensive)
Using all three is the norm. Use Cursor for daily work, and switch to Claude Code for complex problems.
