How to Tell If a Website Uses Loox

Loox is one of the most popular product-reviews apps for Shopify, distinctive for its focus on photo and video reviews. Because its widgets and review data load from a dedicated domain, detecting it is straightforward: open a product page and look for assets and API calls to loox.io plus Loox-branded review widgets. This guide covers every reliable signal, the Shopify-app context, the look-alikes to rule out, and what Loox usage tells you about the store.

What is Loox?

Loox is a Shopify app that collects and displays product reviews, with a signature emphasis on visual social proof: it prompts customers (via automated post-purchase emails) to submit photos and videos with their reviews, then displays them in attractive star-rating widgets, review galleries, carousels and pop-ups. That visual approach — real customer photos next to products — is more persuasive than text reviews alone, which made Loox a favourite of direct-to-consumer (DTC) Shopify brands focused on conversion. It competes with Okendo, Stamped, Yotpo, Judge.me and other Shopify review apps.

For detection, the key context is twofold: Loox is a Shopify app, so finding it strongly implies a Shopify store; and its presence indicates a DTC brand using visual social proof to build trust and lift conversion. Finding Loox tells you the store actively collects and showcases customer photos, a sign of a conversion-focused ecommerce operation. Because Loox loads its widgets and review data from loox.io and brands its widgets, it is easy to confirm on a product page.

How Loox loads and renders

Loox injects its review widgets into Shopify product (and sometimes home/collection) pages, loading its scripts, styles and review data from loox.io (and its CDN/API subdomains). The widgets — a star rating near the product title, a reviews section with customer photos, and sometimes a floating "happy customers" pop-up or a carousel — use loox-prefixed classes and IDs and carry Loox branding ("Reviews powered by Loox" or a Loox logo). The review images are served from Loox's storage, so you will see customer photos loading from Loox/CDN domains.

Because Loox is a Shopify app, it operates within the Shopify theme, so the store will also show Shopify signals (cdn.shopify.com, Shopify markup). The combination of loox.io requests, the Loox-branded photo-review widget, and a Shopify store is the reliable pattern. Knowing these — the loox.io assets/API, the loox-prefixed markup, the Loox branding, and the Shopify context — makes detection quick.

How to tell if a website uses Loox

Confirm at least one strong signal (a loox.io request suffices).

1. Check the Network tab. On a product page, filter for loox. Widget assets and review-data API calls to loox.io confirm Loox.

2. Inspect the review widget. Look for a star rating and reviews section with loox-prefixed classes/IDs, customer photos, and "Reviews powered by Loox" branding.

3. View the source. Search for loox. The widget markup and loox.io references are usually visible.

4. Confirm Shopify. Because Loox is a Shopify app, the store will show Shopify signals (cdn.shopify.com, Shopify markup) — a coherent pairing.

5. Note the photos. Customer-photo reviews (rather than text-only) are characteristic of Loox's visual focus.

What the Loox signals look like

GET https://loox.io/widget/...        ;   GET https://loox.io/api/...   (review data)
<div id="looxReviews" data-product-id="..."> … "Reviews powered by Loox" … </div>
<!-- alongside Shopify: cdn.shopify.com assets, Shopify.theme, etc. -->

Requests to loox.io rendering a Loox-branded photo-review widget, on a Shopify store, are conclusive.

Loox versus other review apps — avoiding false positives

Match the domain to keep Shopify review apps distinct. Loox uses loox.io; Okendo uses okendo.io/cdn-static.okendo.io and oke-prefixed markup; Stamped uses stamped.io; Yotpo uses yotpo.com and yotpo-prefixed markup; Judge.me uses judge.me. Each has a distinct domain and branding. Loox's loox.io domain and photo-review focus are characteristic. The conceptual distinction from Trustpilot is important: Loox is an on-site product-review app (reviews of specific products, hosted within the store), whereas Trustpilot is an independent company-reviews platform. A store may run both, so finding Loox does not exclude Trustpilot.

How reliable is each Loox signal?

Requests to loox.io (widget assets or review-data API) are definitive, as is a Loox-branded photo-review widget with loox-prefixed markup. The Shopify context reliably accompanies it. Customer-photo reviews corroborate Loox's visual focus. The weakest situation is a widget that lazy-loads below the fold, so scroll the product page to trigger it — but the loox.io assets typically load with the page. As a rule, a loox.io request or the Loox-branded widget settles it.

What Loox usage reveals about a store

Finding Loox signals a Shopify DTC brand using visual social proof to convert. Its photo-and-video-review focus indicates a store that understands the persuasive power of real customer imagery and actively collects it via post-purchase emails — a conversion-focused, customer-feedback-driven operation. The near-certain Shopify pairing tells you the platform; the presence of a review app at all marks a store serious about trust and conversion (rather than relying on the bare product page). If you sell ecommerce tools — CRO, retention, email/SMS, UGC, loyalty — a Loox store is an ideal-fit DTC prospect that already invests in social proof. The choice of Loox over text-focused review apps specifically signals a brand that values visual, photo-led merchandising. As with other ecommerce signals, Loox often appears alongside Klaviyo, a Shopify theme, and other DTC-stack tools.

What finding Loox means for sales, agencies and competitive research

For sales and prospecting, Loox marks a conversion-focused Shopify DTC brand investing in visual social proof — a fit for CRO, retention, UGC, email/SMS and ecommerce tools. It signals an active, trust-conscious store.

For agencies and consultants, finding Loox tells you the client values photo reviews and conversion, so engagements can optimise review placement, UGC strategy, or the wider DTC funnel. It signals a Shopify store comfortable installing conversion apps.

For competitive and market research, Loox versus Okendo/Yotpo/Stamped adoption maps how DTC brands in a niche handle reviews and social proof, and the prominence of photo reviews indicates how much each leans on visual UGC.

Loox in the wider DTC stack

Loox sits in the social-proof layer of a Shopify DTC stack. It accompanies a Shopify store, almost always Klaviyo (email/SMS retention), often other conversion apps (upsell, bundles, loyalty), a theme, and analytics plus ad pixels (Meta, TikTok) for acquisition. The post-purchase review-request emails Loox sends may be coordinated with Klaviyo flows. For an auditor, the valuable details are confirmation of Shopify, the presence of Klaviyo and other DTC apps, how prominently photo reviews are displayed, and whether a company-level reviews platform (Trustpilot) also runs; together these reveal a conversion-focused DTC brand and the breadth of its trust-and-retention strategy. There is a strong inference worth drawing from the Loox-plus-Shopify-plus-Klaviyo combination, because it is so common: a store running all three is almost certainly a genuine, actively-marketed direct-to-consumer brand with real revenue, not a hobby shop or a dropshipping test. That single combination is one of the most reliable "this is a serious DTC business" signals you can find, which is why detecting Loox is most valuable not in isolation but as part of reading the whole stack — the company it keeps tells you far more than the review widget itself.

A quick Loox confirmation walkthrough

Open a product page with developer tools on the Network panel and filter for loox. Widget assets and review-data API calls to loox.io confirm Loox. Inspect the reviews section for loox-prefixed markup, customer photos and "Reviews powered by Loox" branding. Confirm the store is Shopify (cdn.shopify.com). The loox.io requests or the Loox-branded photo-review widget confirm Loox.

A quick Loox detection checklist

• On a product page, filter the Network tab for loox; loox.io requests are conclusive.
• Inspect the reviews section for loox-prefixed markup and "Reviews powered by Loox".
• Note customer-photo reviews (Loox's visual focus).
• Confirm Shopify (cdn.shopify.com), since Loox is a Shopify app.
• Distinguish Loox (loox.io) from Okendo (okendo.io), Stamped, Yotpo and Judge.me.
• Check whether Trustpilot (company reviews) also runs alongside it.

Detecting Loox at scale

Checking one store is quick, but mapping review-app adoption across many Shopify domains — to find and segment DTC brands — calls for automation.
