VS Code

Mosaic's recommended editor. Free, everywhere, works with everything.

VS Code — Visual Studio Code — is where you actually type and edit code. Free, works on Mac, Windows, and Linux, with a built-in terminal so you can run things without leaving the window.

Mosaic recommends VS Code because:

  • Most widely used code editor right now, so tutorials match what you see.
  • Handles Python, JavaScript, HTML, and most languages out of the box.
  • Integrated terminal and Git support.
  • Claude Code works inside VS Code's terminal just fine.

You'll install it in Chapter 0-3 if you haven't already.
