What font does Heap use? Lettera Text.

Heap's website sets its type in Lettera Text, on a light #FFFFFF canvas with #111111 text and a #31D891 accent. Copy the palette and fonts, or a ready prompt to build something original in this style with Claude Code, Cursor, Lovable or v0.

      Heap fonts and type scale

      Heap's website sets both headings and body text in Lettera Text. Body text is 16px, section headings 18px and the largest display type 96px, at weight 700. If you can't use Lettera Text, ask your AI for the closest free match and keep the sizes and weights.

      How do I build a site that looks like Heap 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 Heap's look, not its name, logo or copy.
