Isonomy vs AccessComply: A Shopify Accessibility Due-Diligence Guide
Isonomy and AccessComply may appear in the same Shopify App Store search, but a useful comparison requires current evidence about what each product does today.
AccessComply’s documented workflow
AccessComply scans discoverable public storefront pages within the reported page scope and crawler limits. It reports eligible automated-rule findings. When a finding can be mapped safely to a supported Shopify theme or content path, the app can present a candidate for merchant approval.
Supported writes create restore records and run a post-change check. Only confirmed findings are marked resolved. Unsupported, stale, risky, third-party, and judgment-heavy work remains for manual review.
AccessComply does not support every theme pattern, does not perform a complete human WCAG audit, and does not guarantee ADA, EAA, or WCAG compliance.
What to ask Isonomy and AccessComply
| Question | Why it matters |
|---|---|
| Which pages and UI states are scanned? | A public crawl cannot reach every customer, checkout, dialog, or third-party state. |
| What is the exact change mechanism? | Source, Shopify content, runtime output, and recommendations have different lifecycles. |
| Can the merchant preview and approve it? | Production writes need a clear scope and change-control boundary. |
| What happens when source changed meanwhile? | Stale candidates should fail closed rather than overwrite newer merchant work. |
| How is the result verified? | A targeted automated check is useful but not a full conformance audit. |
| Is restore automatic? | Unattended restore can overwrite later work; AccessComply requires merchant confirmation. |
| What remains manual? | Content meaning, complex interactions, third-party apps, media, and documents often require people. |
| What happens on uninstall or theme switch? | Ask about source, content, runtime behavior, stored data, and newly published themes separately. |
AccessComply persistence details
Supported theme changes remain only in the specific modified theme until another edit or update overwrites them. They do not automatically transfer to a different published theme. Supported Shopify content changes remain in the underlying resource. Optional Theme App Extension behavior stops when the app or embed is removed.
Those details are more useful than the blanket phrase “fixes persist.” Ask Isonomy for the equivalent product-lifecycle explanation.
Pricing
AccessComply currently offers Free, Starter at $49 per month, Shield at $99 per month, and Citadel at $399 per month, with optional annual Shopify billing for paid plans. Check pricing for current limits and annual amounts.
Verify Isonomy’s current pricing directly. Do not compare a widget, automated scan, source-change workflow, and managed audit as if they were interchangeable.
Decision rule
Use a development theme, request a live demonstration, inspect the before-and-after storefront, review exclusions, and manually test critical journeys. Choose the product and service mix that makes the remaining work explicit instead of promising a complete outcome.
You can run an AccessComply automated scan without signup before comparing current vendor proposals.
