Boxzilla – WordPress Popup Builder

Boxzilla is a WordPress popup builder for adding targeted popups, slide-ins, and call-to-action boxes to your site. Show a box after a visitor scrolls, waits on the page, views multiple pages, clicks a link, or reaches a specific page element. Each box can contain any WordPress content, including shortcodes from form plugins.

Use Boxzilla for newsletter sign-up forms, content upgrades, product offers, important notices, surveys, or any other message that should appear at the right moment without taking over the whole page.

What you can build with Boxzilla

• Targeted WordPress popups – show boxes only on the posts, pages, or conditions you choose.
• Scroll-triggered slide-ins – open a box after a visitor scrolls past a percentage of the page or reaches a specific element.
• Timed call-to-action boxes – show a message after a set number of seconds on the page.
• Pageview-based prompts – wait until a visitor has viewed several pages before showing a box.
• Click-triggered modals – open a box from a link, button, or URL hash such as #boxzilla-94 .
• Flexible content – add text, images, forms, shortcodes, embeds, or custom HTML to any box.
• Visual appearance controls – choose the position, animation, colors, and box style from the WordPress admin.
• Dismissal control – decide how long a box should stay hidden after a visitor closes it.
• Small front-end script – Boxzilla adds only 6 kB of JavaScript to your website.

Works with your forms and content

Boxzilla works with plugins that output shortcodes, including Mailchimp for WordPress . Add the shortcode to your box content, choose when the box should appear, and publish it.

Premium add-ons

The core Boxzilla plugin is free. Paid add-ons are available for advanced triggers and integrations, including exit-intent popups and time-on-site targeting.
