Switching from Shadowbox JS: common questions

What is the best alternative to Shadowbox JS?

Async JS and CSS is the closest match: it shares the same WordPress.org tags and has 700+ active installs with a 4.2 out of 5 rating.

Which Shadowbox JS alternative has the most users?

Raw HTML, with 10,000+ active installs reported by WordPress.org.

Which Shadowbox JS alternative is rated highest?

CSS & JavaScript Toolbox, rated 4.8 out of 5 by 84 reviewers. Only plugins with at least 50 reviews are counted.

Are these Shadowbox JS alternatives free?

Every plugin listed here is free to install from WordPress.org. Where WordPress.org marks a plugin as commercial, the developer also sells a paid version or add-ons, and that is shown on each plugin.

How are alternatives chosen?

Automatically, from WordPress.org data: plugins that share a category top 10 with Shadowbox JS score highest, then plugins that appear in the same WordPress.org rankings, then plugins with the same tags, weighted so rare tags count more than common ones. Plugins by the same author and plugins rated under 4.0 are left out.

How we choose these alternatives

Nothing on this page is picked by hand. Every day we walk the whole WordPress.org directory, then score every plugin against Shadowbox JS on three signals: sharing a category top 10 counts most, then appearing in the same WordPress.org rankings, then carrying the same tags, with rare tags counting for more than common ones like "wordpress". Plugins by the same author are excluded, so an author's own add-ons cannot fill the list, and so is anything rated below 4.0 or with fewer than 100 active installs. The ten highest scores are what you see, in that order. Full methodology.

The bottom line

Async JS and CSS is the closest match to Shadowbox JS by the data we track, and Raw HTML has the widest reach with 10,000+ active installs. CSS & JavaScript Toolbox shipped the most recent release, on August 26, 2026. The list is rebuilt every day from WordPress.org, so a plugin that stops being maintained drops out on its own.
