Approach

We began with a discovery phase to review Shopify's accessibility standards and identify the most common compliance gaps merchants face. Our team then designed an app architecture that could scan, flag, and auto-fix accessibility issues across themes. Development was carried out using Shopify's App Bridge and Polaris framework, with a focus on real-time scanning and actionable fix suggestions. The app was then tested across a range of Shopify themes and submitted through the official App Store review process.

Solution Delivered

We built a Shopify app that adds accessibility features to any store with one install. Customers can adjust contrast, font size, link highlighting, screen reader cues, and other settings from a single widget. The widget loads fast and does not slow down the store. Merchants get a clean dashboard to manage settings.
