Mercantile, the official WordPress swag store, has relaunched with a block-based storefront powered by the Interactivity API — built as a reference implementation for modern WooCommerce development. Visual references to familiar WordPress touchstones — the metabox, the admin bar, and the project mascot Wapuu — run through the design, alongside nods to open source culture.
The redesign was timed to support the Mercantile booth at WordCamp Europe 2026. The team enabled local pickup at checkout and introduced a set of event-only products to serve in-person shoppers. Fifty orders were completed at the event using in-person payments — a practical test of the new checkout flow under real conditions.
The store serves as a reference implementation for agencies and developers building on modern WordPress and WooCommerce. The Interactivity API — a WordPress developer tool for handling dynamic frontend behaviour without heavy JavaScript frameworks — powers the catalog navigation and modal states. The store runs on WordPress 7.0 and meets accessibility standards throughout, including reduced-motion preferences and colour contrast requirements.
Under the hood, the storefront shows what a modern WordPress and WooCommerce site can do. It is built almost entirely with blocks, including a block-based cart, checkout, mini-cart, and order confirmation, supported by a set of custom theme blocks created for the store.
The redesign is the work of a broad group of contributors who designed, built, tested, and refined the store together. Product pages now surface per-product details such as size, material, and care instructions, and small quality-of-life improvements include automatically selecting a variant when only one option remains in stock.
The team is also building a command-line version of the store aimed at developer workflows. No launch date has been announced, but the team says subtle hints will appear on the site once it is ready. Every purchase made through Mercantile funds the WordPress Foundation.
