Install on your site
Add a chat widget to a plain HTML site
One line before </body> — the universal install.
For a hand-coded or static site, add the snippet to your HTML.
Paste it just before the closing </body> tag of each page you want the widget on (or, if you use a shared layout/partial/include for the footer, add it once there):
<!-- … your page … -->
<script src="https://kelma.chat/embed.js" data-kelma="YOUR_AGENT_ID" async></script>
</body>
</html>
That's it. The async attribute means the browser keeps rendering your page while the script loads — nothing blocks. This same approach works with static-site generators (Hugo, Jekyll, Eleventy, Astro): add it to your base layout template.
