Cite live port congestion data in one line of HTML
The Port Friction Index ranks global container gateways by measured vessel waiting time, rebuilt monthly from our own AIS observation history. When you embed the widget, your readers always see the current month — no screenshots to retake, no numbers going stale mid-story.

This is the exact widget your readers will see.

</p>Optional: auto-resize the iframe
The widget posts its height to the parent window whenever the ranking changes. Add this listener once per page if you would rather not fix the height yourself.
<script>
window.addEventListener("message", function (e) {
if (e.origin !== "https://www.sellexio.co") return;
if (!e.data || e.data.type !== "sellexio:embed-height") return;
document.querySelectorAll('iframe[src*="sellexio.co/embed"]').forEach(function (f) {
if (f.contentWindow === e.source) f.style.height = e.data.height + "px";
});
});
</script>Why embed it
- Always current — the ranking recomputes monthly, so an article you published last quarter still shows live data.
- Independently measured — built from AIS vessel observations, not carrier-published schedules.
- Reader value — every port links through to wait times, p90 exposure and estimated daily cash burn.
- No cookies, no tracking scripts, no sign-up — nothing to disclose in your privacy policy.
Terms of use
- Free for commercial and non-commercial sites, including news, analysis and forwarder pages.
- Keep the attribution link to sellexio.co visible and crawlable.
- Do not republish the underlying numbers as your own dataset — cite the index page instead.
- Scores are indicative planning figures, not a tariff quote or a congestion guarantee.
