How to add Popup Builder to a Bubble app

Embed Popup Builder on Bubble

01

Create a Popup Builder plugin for Bubble on Common Ninja

First, create a Bubble Popup Builder plugin on Common Ninja. On the plugins catalog, find the Popup Builder and enter the Editor.

02

Save the Popup Builder plugin

When you're done creating the Popup Builder plugin, click on the Save Changes button at the right top corner of the editor. If you don't have an account on Common Ninja, you'll have to register first.

03

Copy the Popup Builder Embed Code

When you're ready to add the Popup Builder plugin to your Bubble app, click the Add To Website button at the top bar of the Editor. On the window that opens, click the Copy Icon to copy the plugin embed code. In the next steps, you will paste this code into your Bubble app.

04

Paste the code to your Bubble website’s HTML field.

Next, go to your Bubble app editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the Bubble’s editor. Add it to your page, and paste the Popup Builder Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Popup Builder plugin on your Bubble app.

05

Alternative Method 1: Through the HTML option in the text’s editing area.

If you can't find the HTML/Code widget or module, there's another way to put Common Ninja’s Popup Builder plugin on your Bubble plugin. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your Bubble app’s HTML code.

If you're having trouble finding a widget or a special part in your text editor where you can add the Embed Code, you can try a different way to add the Popup Builder plugin to your Bubble app. You can do this by putting it straight into your Bubble app's HTML code.

Why Use This Widget

Use the Popup Builder widget when you need flexible, targeted overlays for signups, announcements, or offers and do not want to depend on separate tools. You can design popups that match your brand, choose triggers such as scroll, time, or exit intent, and define which pages or segments see them. This is ideal for collecting emails, promoting campaigns, showing gated content, or delivering important notices. When used thoughtfully, popups can lift conversions significantly while staying respectful of user experience. The builder gives you control to test messages, layouts, and timing so you find the balance that works best for your audience.
