What font does CodeSandbox use? Inter.

CodeSandbox's website sets its type in Inter, on a dark #0E0E0E canvas with #F0F0F0 text and a #E3FF73 accent. Copy the palette and fonts, or a ready prompt to build something original in this style with Claude Code, Cursor, Lovable or v0.

      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.
