How to Embed a Widget in Nuclino
Nuclino supports rich URL embeds natively via its Iframely-powered embed system. Paste an Embeddy widget URL and Nuclino renders it as a live, interactive block directly inside your item — no code, no plugins, no workarounds.

Prerequisites
Before embedding, make sure you have the following ready:
- An Embeddy widget: Create one for free at embeddy.ai/dashboard. Your widget must be published (not in draft mode) so it is publicly accessible.
- Your Embed Link: In the Embeddy dashboard, open your widget and copy the Embed Link — the direct URL that looks like
https://embeddy.ai/webhost/WIDGET_ID?widget_props_id=PROPS_ID. - A Nuclino workspace: Any Nuclino plan works — Free, Standard, or Premium. Embeds are supported across all plans.
Where is my Embed Link? In the Embeddy dashboard, select your widget, click the Share / Embed panel, and look for the Embed Link option. It is the direct URL — not the <iframe> snippet.
Method 1: /embed Command
Recommended — most reliable method
Nuclino's slash command menu includes a dedicated Embed option that creates an embed block for any supported URL. Nuclino uses Iframely to resolve URLs into rich embeds.
- 1
Open your Nuclino item
Navigate to the item (page) where you want to display the widget. Click anywhere in the body to place your cursor.
- 2
Type
/embedThe slash command menu appears. Select Embed from the list.
- 3
Paste your Embeddy widget URL
An input field appears. Paste your Embed Link:
https://embeddy.ai/webhost/WIDGET_ID?widget_props_id=PROPS_ID
- 4
Press Enter
Nuclino resolves the URL and renders the widget as a live, interactive embed block. It appears inline within the item content.
Tip: Nuclino items save automatically. As soon as the embed is added, all team members with access to the item will see the widget immediately.
Method 2: Paste URL Directly
Quick alternative — paste on an empty line
Nuclino auto-detects pasted URLs and can convert them into rich embeds. This is the fastest method if the URL is recognized.
- 1
Click on an empty line in your Nuclino item
Place your cursor on a blank line where you want the widget.
- 2
Paste the widget URL
Paste the URL on its own line. Nuclino will show a prompt asking how to handle it:
- →Embed — renders the widget inline (choose this)
- →Link — creates a plain hyperlink
- 3
Select "Embed"
Choose Embed and Nuclino renders your widget as a live inline block.
Note: If Nuclino doesn't recognize the URL for auto-embedding, use Method 1 with the /embed command. It explicitly creates an embed block and works with any valid URL.
Resizing the Embed
Nuclino allows you to resize embeds directly within the editor.
Adjust Width
Click the embed block to select it. Side handles appear that you can drag left or right to change the width. The embed scales within the item's content column.
Adjust Height
Drag the bottom handle of the embed block to increase or decrease its visible height. Users can scroll within the embed frame if the widget content exceeds the visible area.
Reordering: Drag the embed block using its handle to move it to a different position within the item. Nuclino's editor supports full drag-and-drop block reordering.
Limitations
Nuclino embeds are clean and simple, with a few constraints:
Iframely-dependent resolution
Nuclino uses Iframely to resolve URLs into embeds. Most standard HTTPS URLs (including Embeddy widget URLs) work out of the box. Exotic URL patterns or non-standard ports may not be recognized.
No raw HTML/iframe support
Unlike some editors, Nuclino does not allow pasting raw <iframe> code. You must use the URL-based embed approach. This is why the Embeddy Embed Link (URL) is the right choice for Nuclino — not the iframe snippet.
Login-required widgets
Widgets that require Embeddy authentication to view will not render inside Nuclino's embed frame. Set widget visibility to Public in the Embeddy dashboard.
Published items
When you share a Nuclino item publicly, embeds are visible to anyone who can see the item. Ensure your widget content is appropriate for your audience.
Troubleshooting
URL shows as a plain link instead of an embed
This can happen if the URL was not recognized for auto-embedding:
- Use the /embed command instead of pasting directly. This explicitly creates an embed block.
- Ensure the URL is correct. Copy it fresh from the Embeddy dashboard.
Embed appears blank
Verify your widget is published and set to Public visibility in the Embeddy dashboard. Open the Embed Link in a browser tab to confirm it loads correctly.
Widget content is clipped
Resize the embed block by dragging the bottom handle downward. If the widget is still clipped, users can scroll within the embed frame to see all content.
Still stuck? Reach out on Discord or contact support. Share your widget's Embed Link and a screenshot of what you see in Nuclino and we will help you debug it.
FAQ
Does this work with Nuclino's free plan?
Yes. Embeds are available on all Nuclino plans including the free tier.
Can I use embeds in Nuclino's Board, Table, and Graph views?
Embeds live inside the content of individual items. You can view them when you open an item from any view (List, Board, Table, or Graph). The embed is part of the item content, not the view itself.
Will the widget update automatically if I change it in Embeddy?
Yes. Nuclino embeds the live URL, so any changes you make in the Embeddy dashboard are instantly reflected in the Nuclino item without any re-embedding.
