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.
