Claude Code isn't limited to one place. You can use it in your web browser, as a desktop app, inside code editors, or from the command line. Each option has different strengths, so pick the one that fits how you work.

What this means for you

If you've never used a terminal before, start with the web app or desktop app. They're the most familiar interfaces. You can always try the terminal later as you get more comfortable.

What this means for you

You can use multiple interfaces at the same time. Start a session on the web at work, continue it on your desktop at home, or move between them as needed. They all connect to the same Claude.

Moving Between Interfaces

You can start work on one interface and continue on another:

  • Web to Terminal: Use claude --teleport to pick up a web session in your terminal.
  • Any to Any: Use claude --resume to find and continue any previous session.

Tips

  • Start with the web app— it's the fastest way to try Claude Code with zero setup.
  • Move to desktop for file work— when you need Claude to read, organize, or edit files on your computer.
  • Try the terminal when ready— it unlocks the full power of Claude Code, especially automation.
  • You don't have to choose just one— use different interfaces for different situations.
