It works for WooCommerce products and for any WordPress post type: courses, listings, services, recipes, events and more. **ReviewX the No.1 review plugin for WordPress and WooCommerce.** Version 3 is a ground-up rebuild with: a new admin, a new storefront, ReviewX Cloud behind it, and every screen designed to get you more reviews with less work. [Website](https://reviewx.io/) | [Documentation](https://reviewx.io/docs/) | [Pricing](https://reviewx.io/pricing/) | [Changelog](https://reviewx.io/changelog/) ### ✨ What's new in ReviewX 3 * **Rebuilt admin.** A new design system across every screen, responsive down to a phone, with its own light and dark theme. * **Rebuilt storefront.** The reviews section, review form, shortcodes, blocks and My Account form share one design: responsive, right-to-left ready, keyboard accessible and lighter, because the assets load only on pages that show reviews. * **Light & dark mode that follows your theme.** Reviews turn dark on dark pages and switch live when a visitor toggles your theme's dark mode. ReviewX recognises the usual dark mode classes and attributes and the page background, you can add your theme's own marker, and every post type, shortcode, block and widget can also stay always light or always dark. * **Settings for every post type.** Widget settings and Appearance → Customize → ReviewX keep a look per post type: products are the default, other post types inherit it or get their own. The Customizer offers 147 options with a live preview. * **Shortcode Designer.** Pick any ReviewX shortcode, set it up with plain options and watch a live preview with sample reviews on desktop and mobile, on a light or a dark page. Copy it as a shortcode or as a PHP template line. * **Blocks and builders.** Gutenberg blocks with live previews in the editor, Elementor widgets, classic widgets, and shortcodes for Divi, Oxygen and any other builder. * **Tools that keep your data clean.** Data sync with history, cache management, and a cleanup tool that finds duplicate reviews and reviews left behind in the cloud. * **ReviewX Cloud dashboard.** See every connected store in one place, with store insights that tell you what to do next. ### 🚀 Why store owners choose ReviewX * **More reviews, on autopilot.** Review request emails, follow-ups and discounts for reviews bring in the feedback most customers forget to leave. * **More trust, more sales.** Verified buyer badges, a recommendation score, photos and videos show new shoppers what real customers think. * **Better SEO.** Review rich snippets can show your star rating in Google search results. * **Real insight.** Multi-criteria ratings show which part of a product delights customers and which part needs work. * **Fits your store.** Any theme, any post type, any page builder, in your colours and your language. ### 🆓 Free features * **[Multi-criteria ratings](https://reviewx.io/docs/manage-multiple-review-criteria/):** let customers rate what matters, such as quality, value or fit (2 criteria on the free plan). * **[Photo reviews](https://reviewx.io/docs/photo-video-review/):** customers add photos to their reviews. * **[Review request emails](https://reviewx.io/docs/woocommerce-review-reminder-email/):** ask customers for a review after their order, one by one or in bulk, with test emails and email logs.

A [review on WordPress.org](https://wordpress.org/support/plugin/reviewx/reviews/) helps other store owners find it. == Installation == 1. In WordPress, go to **Plugins → Add New**, search for **ReviewX** and click **Install Now**, then **Activate**. Or upload the `reviewx.zip` file under **Plugins → Add New → Upload Plugin**. 2. Open **ReviewX** in the admin menu and create your free ReviewX Cloud account or log in. Your products and existing reviews sync automatically. 3. Set up your review criteria in **ReviewX → Reviews → Review settings**, choose the look in **Widget settings**, and turn on review emails in **ReviewX → Review Reminder**. == Frequently Asked Questions == = Is ReviewX free? = Yes. The free plan covers one store and includes multi-criteria ratings, photo reviews, review request emails, discounts for reviews, Google rich snippets, reviews on any post type and every page builder integration. [Pro and Agency plans](https://reviewx.io/pricing/) add more criteria, video reviews, automatic reminders, moderation tools and more stores. = Do I need WooCommerce? = No. With WooCommerce, ReviewX replaces the product reviews tab and can send review emails after orders. Without it, ReviewX adds reviews to any post type you choose. = What happens to my existing WooCommerce reviews? = They sync to ReviewX automatically when you connect, with their ratings. Earlier reviews have no criteria ratings, because they were written before you used ReviewX. = Does ReviewX work with my theme? = Yes. The reviews section uses its own styles, follows your theme's light and dark mode and can take your brand colours. If your theme marks its dark mode in an unusual way, enter that class or attribute in **Widget settings → Match the theme's light and dark mode**. = Can I show reviews outside the product page? = Yes. Use the Gutenberg blocks, the Elementor widgets, the classic widgets or any shortcode. **ReviewX → Shortcodes** builds the shortcode for you with a live preview. = How many review emails can I send? = The free plan includes 20 emails a month through ReviewX and paid plans 200. Connect your own SMTP server in **ReviewX → Settings** to send without a monthly limit. = Does ReviewX slow down my site? = No. Its scripts and styles load only on pages that show reviews, and rating summaries are cached. ReviewX also clears the common page caches when reviews or settings change. = Is ReviewX GDPR friendly? = You can add a consent checkbox to the review form, and reviewers can review anonymously on paid plans. See **External services** above for the data ReviewX Cloud processes. = What happens if I uninstall ReviewX? = Your reviews stay in WordPress as regular WooCommerce or WordPress reviews. Only the criteria ratings and ReviewX features are no longer shown. = Can I translate ReviewX? = Yes. ReviewX is translation ready and works with WPML and Loco Translate. == Screenshots == 1.

ReviewX recognises the usual dark mode classes and attributes (such as .dark, .dark-mode, data-theme="dark", data-bs-theme and popular dark mode plugins), the page's color-scheme and the background behind the widget, and switches live when visitors toggle the theme. - New: themes with their own dark mode marker can be matched exactly: enter its class, ID or attribute as a CSS selector in Reviews → Widget settings or Appearance → Customize → ReviewX → Light & dark mode. - New: light and dark mode per post type, stored in ReviewX Cloud with the other widget settings: match the theme, always light or always dark, set in Reviews → Widget settings or the Customizer, which also gives every colour option its own dark colour. Reviews kept light on a dark page (or dark on a light one) bring their own background, so they stay readable. - New: every shortcode takes theme="auto", "light" or "dark"; left out, it follows the post type's setting (match the theme by default). The Shortcodes screen, every ReviewX block, classic widget and Elementor widget offer it as "Light / dark mode". - New: Widget settings and Shortcodes previews can show a light or a dark theme page, and "Desktop" now shows the real desktop layout, scaled to fit. - Fixed: the My Account "Add review" button could stop opening the review form once dark mode detection ran. - New: post type filter on the Reviews page. "All reviews" is the default; pick a post type to narrow the list, the tabs and the rating summary. - New: Tools → Duplicate & orphan reviews finds reviews left in ReviewX Cloud after their WordPress review was deleted, and lets you remove them one by one or all at once. - Fixed: a review that could not be saved in WordPress no longer reaches ReviewX Cloud, so it cannot turn into an orphan or skew product ratings. - Fixed minor issues. = 2.5.1 - 08-27-2026 = - Regular Update. -
