Overview
Store owners ask which platform keeps them safest from ADA claims. The honest answer: the platform choice moves the risk around, but the owner’s choices dominate the outcome everywhere. Theme, plugins, and content decide far more than the logo in the footer. The lawsuit statistics back this up: all three platforms appear constantly in ADA filings.
One rule applies to all three: the merchant, not the platform, gets sued.
Shopify
The good. Hosted checkout with a solid baseline, first-party themes built with accessibility in mind, and a curated app store. The floor is relatively high, and you cannot break the checkout Shopify hosts.
Where it breaks. Third-party themes and apps, and merchant content. The details are in Does Shopify have built-in ADA compliance?
The trap. The curated feel creates false confidence. Apps pass Shopify’s review without any accessibility check, and owners assume otherwise.
WooCommerce
The good. Total control. With an accessibility-ready WordPress theme and disciplined plugin choices, you can build an excellent store that meets every criterion.
Where it breaks. The same total control. The plugin ecosystem has no accessibility gate, page builders generate deeply nested markup that confuses screen readers, and every update is your responsibility. WooCommerce stores show the widest variance: the best and the worst stores we see both run on it.
The trap. Plugin sprawl. Twenty plugins means twenty independent chances to inject an unlabeled button or a focus trap, and no one reviewing the combination.
BigCommerce
The good. Hosted platform with WCAG-conscious core themes and decent accessibility documentation. Structurally similar to Shopify’s story.
Where it breaks. Same pattern: third-party themes, injected scripts, and content. Smaller theme and app ecosystems mean fewer options, which cuts both ways: less choice, but also less unvetted code in circulation.
What is identical on all three
- Alt text on your product images: always your job, on every platform.
- Color and contrast choices: your job. See color contrast in Shopify themes; the math is platform-independent.
- Third-party widgets: your risk everywhere, because they render into your pages.
- The legal standard: WCAG 2.1 AA everywhere.
- The verification: a manual audit checks your rendered store, whatever runs underneath it.
Example
A store migrates from WooCommerce to Shopify “for compliance,” carrying over the same product catalog with no alt text and rebuilding the same low-contrast brand palette in a new theme. Their next scan looks nearly identical to the old one. The platform changed; the failures were content and design decisions, so they came along with the move. Six months of migration work bought nothing that two weeks of remediation would not have.
Common mistake
Replatforming instead of auditing. Migration costs 10 to 50 times what remediation costs, takes months, and without an audit you reproduce the same issues on the new platform. Audit first. In almost every case the store you already have is fixable, and the audit report tells you exactly what the fix list is.
