PostHog design: colors, fonts and an AI prompt.

PostHog's website sets its type in Round Hog, on a light #E5E7E0 canvas with #111111 text and a #F54E00 accent. Copy the palette and fonts, or a ready prompt to build something original in this style with Claude Code, Cursor, Lovable or v0.

      What font does PostHog use?

      PostHog's website sets both headings and body text in Round Hog, with ui-monospace for code. Body text is 14px, section headings 20px and the largest display type 72px, at weight 700. If you can't use Round Hog, ask your AI for the closest free match and keep the sizes and weights.

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