Boxzilla – WordPress Popup Builder

81 Quality Score

Active Installs

19/30

With 20,000 active installs, Boxzilla sits well behind mainstream popup plugins like Popup Maker or OptinMonster, suggesting a smaller but loyal niche audience rather than mass adoption.

Update Freshness

25/25

The plugin was last updated on June 22, 2026 and is tested against WordPress 7.0, which is an exceptionally current maintenance signal for a popup tool.

User Rating

14/15

A 96 out of 100 rating from 132 reviews is excellent, though the relatively small sample size means the score carries slightly less statistical weight than plugins with thousands of ratings.

Support Health

8/15

Zero support threads and zero resolved tickets is a concerning signal that either the plugin rarely breaks or that users have nowhere effective to turn when it does.

WP Compatibility

15/15

Compatibility scores full marks thanks to broad PHP and WordPress version support, going back to WordPress 4.6 and PHP 7.4, which keeps it accessible on legacy hosting.

What It Does

Boxzilla is a WordPress plugin for creating popup and slide-in boxes that you can trigger based on user behaviour such as exit intent, scroll depth, or time on page. Boxes can contain forms, calls to action, discount offers, or simple notices, and they work with most WordPress themes without forcing shortcodes into your content.

Who It's For

Boxzilla is a good fit for site owners running small to mid-sized businesses who want a lightweight, no-fuss popup tool without the bloat of a full marketing automation suite. It suits bloggers, Shopify-adjacent stores, and SaaS founders who need basic opt-ins and announcement bars rather than advanced A/B testing funnels.

Who Should Skip It

If you need advanced features like multivariate testing, gamified multi-step popups, or deep CRM and email platform integrations, Boxzilla will feel underpowered and you will want a heavier alternative. Agencies running dozens of client campaigns should also skip this because the lack of resolved public support threads suggests limited hands-on help when things break.

The Bottom Line

Boxzilla is a clean, actively maintained popup plugin that scores a solid 81.16 out of 100, with standout marks for maintenance and compatibility but a worrying lack of public support activity. It is a sensible, lightweight choice for simple opt-ins, but power users and agencies will likely outgrow it. Compared with alternatives averaging 700,000 installs, its 20,000-install footprint tells you it is a niche tool rather than a category leader.

Related Plugins

Popup Maker 90/100

Choose Popup Maker if you want the same WordPress-native approach but with 700,000 installs, a larger community, and far more proven support track record.

OptinMonster 87/100

Pick OptinMonster when you need enterprise-grade targeting, A/B testing, and integrations with major email platforms that Boxzilla does not provide out of the box.

Firelight Lightbox 86/100

Firelight Lightbox is the better option if your main need is image and video lightboxes rather than marketing-driven opt-in popups.

Popup Builder 85/100

Popup Builder makes more sense if you want a wider variety of popup styles and themes at a lower price point, backed by 200,000 installs.

Popup builder with Gamification, Multi-Step Popups, Page-Level Targeting, and WooCommerce Triggers 84/100

This option is worth picking if you specifically want gamified multi-step popups, WooCommerce triggers, and page-level targeting beyond what Boxzilla offers.
