Live chat for WordPress and WooCommerce, without another plugin to maintain

Sellio does not ship a WordPress plugin, and you do not need one. The widget is a single script tag: paste it into your theme's footer or into the code-snippet plugin you already use, and it runs on every page, WooCommerce included.

The snippet, and where it goes on WordPress

Paste this into your theme's footer, before </body>, or a code-snippet plugin set to the footer. Replace the placeholder with the widget key from Settings, then Install; the snippet there already carries it.

  1. Classic themes: Appearance, then Theme File Editor, then footer.php. Paste above </body>.

  2. Block themes: install a code-snippet plugin such as WPCode, add a footer snippet for all pages, paste, activate.

  3. Purge any cache plugin and reload the site.

  4. Framework guides for Next.js, Vue, Nuxt, Svelte and Astro are in the install docs.
index.html
<script>
  window.sellioSettings = { widgetKey: "YOUR_WIDGET_KEY" };
  (function (w, d) {
    w.SellioWidget = w.SellioWidget || [];
    var s = d.createElement("script");
    s.src = "https://sellio.chat/widget/embed.js";
    s.async = true;
    d.head.appendChild(s);
  })(window, document);

What the widget gives a WordPress site

One script tag

The whole install is one snippet before the closing body tag. No build step, no plugin to keep updated.

Matches your site

Brand colours, launcher, avatar, header text, light or dark. The chat reads as part of the page.

Pre-chat form and help center

Ask for a name or email first if you want, and let visitors read your help articles inside the widget.

An AI agent that answers first

Trained on your pages and documents, it takes the first reply on website chat and hands over when unsure.

Show it where it helps

Only on some pages, hidden on others, by country or IP, and hidden when nobody is online.

Every reply in one inbox

Website chats land beside WhatsApp, Instagram, Telegram and email, with assignment, notes, tickets and analytics.

Installing on WordPress

  1. Step 1

    Copy your snippet

    In Sellio, Settings, then Install.

  2. Step 2

    Pick where it goes

    Classic theme: Appearance, Theme File Editor, footer.php, before </body>. Block theme or a site you do not want to edit: a code-snippet plugin such as WPCode, set to the footer on all pages.

  3. Step 3

    Save and reload

    The launcher appears site-wide. Cache plugins may need a purge.

WordPress questions

Not yet. The widget is one script tag, so a plugin would only paste it for you. Use your theme footer or a snippet plugin you already trust.

  • Classic themes: Appearance, then Theme File Editor, then footer.php. Paste above the closing body tag.
  • Block themes, or a site you do not want to edit: a code-snippet plugin such as WPCode, set to the footer on all pages.
  • Nothing to keep updated. There is no build step and no plugin version to maintain; the snippet loads the current widget.

The install docs walk through both routes.

Chat on WordPress with one snippet, not one more plugin.
