Embeds

Put a Voydar vessel card, port board or mini map on any web page with an iframe. No key, no account, no cookies. Widgets are cached snapshots (vessel card 15 minutes, port board 30, map 5) and show only facts the public page shows. Add ?theme=light or ?theme=dark to force a theme; without it the widget follows the reader's system. The optional embed.js script sizes the iframe to its content. The "Embed" button on every vessel and port page builds the snippet for you.

<iframe src="https://www.seadar.io/embed/vessel/9811000" title="EVER GIVEN · Voydar"
  width="100%" height="300" style="border:0;max-width:480px" loading="lazy" data-seadar-embed></iframe>
<script async src="https://www.seadar.io/embed.js"></script>
