Complyko vs TestParty: three-pillar scanner vs accessibility remediation

TestParty is a managed accessibility remediation service for Shopify stores. They scan for WCAG violations and deliver source code fixes via GitHub pull requests. It is a hands-on, done-for-you service aimed at brands that want someone else to handle the accessibility work.

Complyko is an ecommerce compliance scanner covering three pillars in one scan: accessibility, PCI DSS 4.0 and privacy. It is self-serve. You run a scan, get a report with violation details and fix suggestions, and act on the findings yourself or with your development team.

These are different products addressing different needs. This comparison covers how each works, what they cover and when one makes more sense than the other.

How TestParty works

TestParty operates as a managed service. The engagement starts with an initial audit and remediation sprint, typically delivered in two weeks. Fixes are submitted as GitHub pull requests directly to your Shopify theme repository, so your development team reviews and merges them through a standard code review process.

Ongoing, TestParty provides monthly manual audits that include screen reader testing, daily automated scanning via their Spotlight product and CI/CD integration via Bouncer to catch regressions in your deployment pipeline. Clients receive monthly certificates of compliance documenting the state of their accessibility.

The service is primarily built around Shopify. It is designed for brands that want to hand off accessibility entirely and receive a maintained, certified result.

How Complyko works

Complyko uses Playwright to navigate real ecommerce flows: homepage, product pages, cart, checkout and account. axe-core runs at each flow step alongside custom ecommerce checks for things axe does not cover, including cart quantity controls, price announcements and checkout form autocomplete attributes.

The same scan also runs PCI DSS 4.0 checks on payment pages. Requirement 6.4.3 covers script integrity: third-party scripts on checkout pages need to be authorized and integrity-verified. Requirement 11.6.1 covers HTTP security headers and change detection. Complyko checks both on every scan.

Privacy checks run on the homepage before any cookie dismissal, so the banner is visible for detection. The 14-item privacy checklist covers GDPR consent banner presence, reject button, cookie settings access, CCPA Do Not Sell links, pre-consent tracking, Google Consent Mode configuration, dark patterns and consent persistence across page navigations.

Results come back as a scored HTML report grouped by pillar. Violations include the page, the element, the rule and a fix suggestion. Complyko works across Shopify, WooCommerce, Magento and BigCommerce.

Feature comparison

Different products for different needs

TestParty is a premium managed service. The value proposition is clear: they do the accessibility work for you. You get pull requests, certificates and ongoing manual audits. If your team has no accessibility expertise and you want someone else to own it, that is what TestParty delivers.

Complyko is a scanner. It finds violations across three pillars and tells you what to fix. It does not submit pull requests or provide a managed team. The tradeoff is coverage: Complyko surfaces PCI DSS 4.0 script issues and privacy compliance gaps that TestParty does not cover at all.

TestParty goes deeper on accessibility remediation. Complyko goes broader on compliance coverage. Neither replaces the other entirely for every use case.

When to choose each

Choose TestParty if you are a Shopify store with an accessibility lawsuit risk you want actively managed, your team cannot absorb the remediation work and you have budget for $599 to $5K per month in a managed engagement.

Choose Complyko if you need a single scan covering accessibility, PCI DSS 4.0 and privacy, you operate on WooCommerce, Magento or BigCommerce alongside or instead of Shopify, or you are an agency managing multiple stores and need per-store compliance visibility at scale.

Some teams use both: Complyko for broad compliance scanning across all three pillars and TestParty for deep accessibility remediation on their primary Shopify store. The overlap on accessibility scanning is real, but the non-overlapping coverage (PCI and privacy from Complyko, managed fixes from TestParty) means they can complement each other.
