CodeSandbox fonts and type scale
CodeSandbox's website sets both headings and body text in Inter, with ui-monospace for code. Body text is 16px, section headings 24px and the largest display type 120px, at weight 600. If you can't use Inter, ask your AI for the closest free match and keep the sizes and weights.

How do I build a site that looks like CodeSandbox with AI?
Open the Prompt tab above, change its first line to what you are building, and paste it into Lovable, v0, Bolt, Claude Code or Cursor. For a whole project, install the Claude skill or the Cursor rule instead, so every screen keeps the style. Build something original: keep CodeSandbox's look, not its name, logo or copy.
