EMBED THE BADGE

Most websites, Webflow embeds, custom HTML blocks.

<a href="https://runs.space/unitpost" target="_blank" rel="noopener">
  <img src="https://runs.space/api/badge/unitpost" alt="Unitpost is racing to orbit on runs.space" width="240" height="54" />
</a>

Every embed is a live fuel gauge that links back to your rocket. Once the badge is verified, the link from your rocket page to your product turns dofollow — until then it stays nofollow. The embed gives runs.space the link; the dofollow on your listing is what you get back.
