Use Claude Code for building entire projects from scratch autonomously. Use Cursor for visual, IDE-integrated AI editing on existing codebases. Use GitHub Copilot for inline autocomplete while you type. They solve different problems and many developers use 2-3 of them together.
The key difference: Copilot completes your code line by line, Cursor edits files you point it to, and Claude Code works independently — you describe a task, walk away, and come back to finished code. If you want an AI that works while you sleep, Claude Code on a persistent server is the answer.
GitHub Copilot: autocomplete on steroids
Best for: inline code completion, writing tests, boilerplate, learning new APIs. It predicts what you will type next inside your editor. You stay in control, it speeds you up. Price: $10/month.
Limitation: it only suggests the next few lines. It cannot plan, refactor across files, or work independently.
Cursor: the AI-native IDE
Best for: multi-file edits, visual diff review, working with existing codebases, teams. It replaces VS Code with an AI-first editor. You chat with your codebase, select code to modify, review diffs visually. Price: $20/month.
Limitation: requires your attention. You guide it through each change. It does not work autonomously.
Claude Code: the autonomous agent
Best for: building entire features from scratch, complex refactoring, tasks that take more than a few minutes. You describe what you want and Claude works independently — reading files, writing code, running commands, fixing errors. Price: API usage ($3-20 depending on task size).
Limitation: needs a persistent environment to run long tasks. Running locally, it dies when you close your laptop. Solution: run it on a managed VPS that stays on 24/7.
Can you use them together?
Yes, and many developers do. Common setup: Claude Code on a persistent server for big tasks, Copilot or Cursor in your daily editor for small edits. Give Claude a large feature to build overnight, use Cursor for quick fixes during the day.
The bottom line
There is no single best tool. But if you want an AI that builds while you are away from your computer, Claude Code on a 24/7 server is the only option that works autonomously. The other tools need you present.
