How to add testimonials to Duda

Whether you use Duda's Custom HTML widget, Section builder, or Blog, you can embed a self-updating testimonial wall with just two lines of HTML. No plugins, no monthly fees, no manual updates.

The universal snippet

This works on any Duda editor mode. Copy your space ID from your Vouchnest dashboard, replace YOUR_SPACE_ID, and paste both lines into any Custom HTML widget on your Duda site.

HTML snippet

<script src="https://cdn.vouchnest.com/widget.js" data-space-id="YOUR_SPACE_ID" async></script>
<div id="vouchnest-wall"></div>

Self-updating

Approve a testimonial in your dashboard — it appears on the wall automatically. No redeploy needed.

Responsive

The wall adapts to any container width. Works on desktop, tablet, and mobile out of the box.

Fast-loading

The widget script is small and loads asynchronously — it won't block your page render.

No code? Use the hosted wall page

Every Vouchnest space gets a hosted wall page at vouchnest.com/wall/your-space-slug. Link to it from your Duda site menu, a button, or your footer. No HTML embedding needed — just paste the URL. It’s fully public and updates automatically.

Frequently asked questions

Does Duda support custom embeds?+

Yes. Duda has a built-in Custom HTML widget that accepts any HTML or JavaScript snippet. You can paste the Vouchnest embed code directly into it. Duda also supports iFrame embeds for the hosted wall approach.

Will it work on all device views?+

Yes. The Vouchnest widget is fully responsive and Duda's Custom HTML widget adapts to desktop, tablet, and mobile breakpoints automatically. You can fine-tune visibility per device in Duda's editor if needed.

Can I use it with Duda's CMS?+

Yes. If you use Duda's CMS to manage dynamic content, you can embed the Vouchnest widget on CMS-driven pages using the Custom HTML widget. The wall will appear on all pages that use the same template.

Is custom code available on all plans?+

The Custom HTML widget is available on most Duda plans. If your plan restricts custom code, use the iFrame embed or hosted wall link method instead — both work on any plan.

Will it break on site updates?+

No. The Vouchnest widget is loaded from our CDN independently of your Duda site. When you update your site or change templates, the embed remains intact and continues working without interruption.
