Complyko vs Consentmo: compliance scanner vs Shopify consent app

Consentmo is a Shopify-native consent management app used by over 90,000 merchants. It provides cookie consent banners, geo-targeted compliance rules, Google Consent Mode v2 integration and a privacy center, all billed through the Shopify app store.

Complyko is an ecommerce compliance scanner that tests real checkout and cart flows across three pillars: WCAG 2.1 AA accessibility, PCI DSS 4.0 script requirements and privacy compliance. It does not provide a consent banner. It tests whether the one you have is working correctly.

These two products solve different problems. This page documents what each does, where they overlap and where they do not.

How Consentmo works

Consentmo installs as a Shopify app and injects a cookie consent banner into your storefront. The banner auto-blocks third-party scripts until a visitor gives consent. Geo-targeting rules apply the right consent model per jurisdiction: GDPR opt-in for EU visitors, CCPA opt-out for California visitors and similar configurations for over 40 regulations.

Consentmo supports Google Consent Mode v2 and IAB TCF 2.4, which means it integrates with Google Ads and other advertising platforms that read consent signals before firing tags. It provides a privacy center where visitors can submit data subject access requests (DSAR), review their consent choices and manage their preferences.

On the accessibility side, Consentmo includes a widget toolbar: bigger cursor, dyslexia-friendly fonts, bionic reading mode and similar user preference settings. It also includes an alt text manager for product images and an AI-powered cookie scanner that categorizes cookies automatically. The company holds ISO 27001 and SOC 2 certifications.

Consentmo is Shopify-only. It is billed through the Shopify app store and is not available for WooCommerce, Magento, BigCommerce or custom ecommerce platforms.

How Complyko works

Complyko runs a Playwright headless browser through your store's real user journeys. It navigates the homepage, adds a product to cart, proceeds through checkout and visits account pages. At each step, it checks what is actually happening in the browser, not what your configuration says should happen.

For privacy, Complyko verifies behavioral compliance: does your consent banner appear before tracking fires? Does the reject button work? Does consent persist when a visitor navigates to a second page? These tests catch cases where a CMP is installed but misconfigured, where tag managers fire before consent is given or where reject flows do not propagate correctly.

For accessibility, Complyko runs axe-core plus a custom ecommerce check layer on each page state in the checkout and cart flows. Violations are reported as code-level findings with WCAG criterion references and suggested fixes. An overlay widget is not a substitute for this: it masks issues without fixing them.

For PCI DSS 4.0, Complyko checks payment pages for script integrity requirements (Req 6.4.3) and security headers (Req 11.6.1), which became mandatory in March 2025.

Complyko works on any ecommerce platform. It has no installation step: you give it a URL and it scans.

Feature comparison

Complementary tools

Consentmo and Complyko are not competing for the same job. Consentmo provides the consent infrastructure: the banner that appears on first visit, the script blocking logic, the geo-targeting rules and the privacy center for data subject requests. If you are on Shopify and need a CMP, Consentmo is a credible option.

Complyko tests whether that infrastructure is working. A CMP installation is not the same as a compliant site. Common failure modes include tag managers that fire before consent is given, reject buttons that dismiss the banner without actually stopping tracking and consent that does not persist when a visitor navigates from the homepage to a product page. These are configuration and integration failures that only behavioral testing can detect.

Beyond privacy, Consentmo does not address WCAG accessibility code violations or PCI DSS 4.0 payment page requirements. These are separate compliance areas with their own legal exposure: ADA and EAA for accessibility, PCI DSS for payment security. A store running Consentmo still needs to test these separately.

A Shopify store can use Consentmo for its CMP and Complyko to verify that the full compliance picture is accurate: privacy behavior, accessibility and PCI. The two products cover different things.

When to choose which

Choose Consentmo if you need a Shopify consent banner with geo-targeting, Google Consent Mode v2 integration and a privacy center for DSAR management. It handles the infrastructure side of privacy compliance at a low price point and integrates natively with the Shopify ecosystem.

Choose Complyko if you need to test whether your compliance actually works. This includes verifying that tracking does not fire before consent, that your checkout flow passes WCAG 2.1 AA and that your payment pages meet PCI DSS 4.0 script requirements. Use both for complete coverage.

Frequently asked questions

What does Consentmo do?

Consentmo is a Shopify-native consent management app used by over 90,000 merchants. It provides cookie consent banners with auto-blocking, geo-targeted compliance per jurisdiction (GDPR opt-in for EU, CCPA opt-out for California), Google Consent Mode v2, IAB TCF 2.4, a privacy center with DSAR forms, an accessibility widget and an AI-powered cookie scanner.

What does Complyko do that Consentmo does not?

Complyko tests whether your compliance setup actually works. It runs a headless browser through your checkout and cart flows to verify that tracking does not fire before consent, that reject buttons function correctly and that consent persists across page navigation. It also covers WCAG 2.1 AA accessibility scanning with axe-core and PCI DSS 4.0 script monitoring for payment pages, neither of which Consentmo addresses.

Can I use Consentmo and Complyko together?

Yes. Consentmo provides the consent infrastructure: banners, geo-targeting, cookie blocking and the privacy center. Complyko tests whether that infrastructure works correctly and covers the compliance areas Consentmo does not touch, including WCAG accessibility code violations and PCI DSS payment page script requirements. The two products are complementary.

Does Consentmo work outside Shopify?

No. Consentmo is a Shopify app billed through the Shopify app store. It is not available for WooCommerce, Magento, BigCommerce or custom ecommerce platforms. Complyko is platform-agnostic and scans any ecommerce site.
