Complyko vs Clym: ecommerce flow scanner vs consent and widget platform

Clym positions itself as a combined privacy and accessibility platform. It provides a consent management widget, an accessibility overlay toolbar and governance tools for GDPR, CCPA and other regulations. Complyko is an ecommerce compliance scanner that navigates real checkout and cart flows to find code-level violations across accessibility, PCI DSS 4.0 and privacy.

They are not direct competitors. Clym gives you tools to manage compliance. Complyko tells you whether your compliance setup is actually working and what violations exist in your store code. For many teams, the two serve different purposes.

How Clym works

Clym delivers compliance as a JavaScript widget. When installed on your site, it adds two main capabilities.

The consent management layer detects visitor location and fires a cookie consent banner based on applicable regulations. It covers GDPR, CCPA, IAB TCF v2 and Google Consent Mode V2. It includes a governance portal for managing data subject access requests (DSARs), a policy generator and 190+ regulation presets for different jurisdictions.

The accessibility layer is an overlay toolbar. It provides six pre-built profiles targeting vision impairment, cognitive disabilities and motor disabilities, plus manual controls for text size and contrast. This is a user accommodation layer: it lets individual visitors adjust their experience. It does not scan your site for violations or fix code-level issues.

Clym is SOC 2 certified and operates primarily as a widget-based consent and accommodation platform, not a scanner.

How Complyko works

Complyko runs a headless browser that navigates your real ecommerce flows. It adds products to cart, proceeds through checkout and interacts with your account pages the same way a customer would.

The scanner covers three pillars. Accessibility testing uses axe-core plus custom ecommerce checks for price announcement, cart quantity controls, checkout form labels and keyboard navigation through dynamic flows. PCI DSS 4.0 testing covers script inventory on payment pages, Subresource Integrity enforcement, tag manager presence, CSP and HSTS headers and obfuscated JavaScript detection. Privacy testing checks whether your consent banner fires before tracking, whether the reject path works, whether consent persists across pages, whether dark patterns are present and whether Google Consent Mode is configured correctly.

Results are code-level findings: the specific element, the page, the rule violated and what to fix. Complyko does not install anything on your site.

Feature comparison

The overlay limitation

Clym's accessibility offering is a toolbar overlay. This distinction matters for anyone using it as an ADA or EAA compliance strategy.

An overlay provides user accommodations: a visitor can enable a high-contrast mode or increase text size. That is a legitimate and useful feature. But it does not change the underlying code. Missing form labels are still missing. A broken heading hierarchy is still broken. A keyboard trap in your checkout flow still traps keyboard users. A payment step that is inaccessible to screen readers is still inaccessible.

Courts adjudicating ADA web accessibility claims do not accept overlay widget installation as a compliance defense. The legal standard is whether a disabled user can actually use the site. If a screen reader user cannot complete a purchase, the barrier exists regardless of what JavaScript is loaded on the page. For the full background on why overlays fall short legally and technically, see our post on why accessibility overlay widgets do not work.

The European Accessibility Act, enforced since June 2025, applies similar logic. Compliance requires that ecommerce flows are genuinely usable, not that an accommodation toolbar is present.

When to choose Clym

Clym is a reasonable choice when you need a consent management platform. If you do not have a CMP and need to handle GDPR consent, CCPA opt-out, TCF v2 and Google Consent Mode in one tool, Clym provides that. Its DSAR handling and policy generator add governance infrastructure that makes sense for teams managing privacy operations across multiple regulations. The $49/mo starting price is competitive.

If your primary goal is a user accommodation layer, the toolbar profiles serve that use case. Just understand that accommodation and compliance are not the same thing.

When to choose Complyko

Complyko is the right choice when you need to know what violations exist in your store code. If you face ADA lawsuit risk, need to demonstrate WCAG 2.1 AA compliance or are preparing for EAA enforcement, you need code-level findings, not a toolbar.

If you are unsure whether your existing Clym consent setup is actually working, Complyko's privacy behavioral tests can answer that: does the banner fire before tracking? Does the reject path work? Does consent persist across pages?

If you need PCI DSS 4.0 coverage for requirements 6.4.3 and 11.6.1, Complyko covers both. No other tool in this category bundles accessibility scanning, PCI script monitoring and privacy behavioral testing for mid-market ecommerce.

Frequently asked questions

What is the difference between Complyko and Clym?

Clym provides a JavaScript widget that adds cookie consent management and an accessibility toolbar to your site. Complyko is a headless browser scanner that navigates real ecommerce flows, finds code-level WCAG violations and tests whether your consent setup actually works. They solve different problems.

Does Clym's accessibility widget achieve WCAG compliance?

No. Clym's accessibility overlay provides a user-facing toolbar with profiles for vision, cognitive and motor needs. It does not find or fix violations in the underlying code. Missing form labels, broken heading hierarchies, keyboard traps and inaccessible checkout flows remain. Courts have not accepted overlay widgets as ADA compliance.

Does Complyko provide a consent management platform?

No. Complyko tests whether your existing consent setup works correctly: whether the banner fires before tracking, whether the reject path is accessible, whether consent persists across pages and whether dark patterns are present. If you need a consent management platform, Clym provides one. Complyko tells you if it is working.

Which tool covers PCI DSS 4.0?

Complyko covers PCI DSS 4.0 requirements 6.4.3 and 11.6.1, including script inventory, SRI checks, CSP headers and tag manager analysis on payment pages. Clym does not cover PCI DSS.
