Circuit

Circuit looks like a well-run tech store: graphite navigation, bright white product cards and full, uncropped product photos that match the box. Search sits at the top of every screen, and specs are set in clear, easy-to-scan type. It suits accessory brands, gadget makers and multi-brand electronics retailers.

Shoppers save their phone or device once, and every accessory tells them whether it fits, which cuts down on wrong-fit returns. They can compare up to three products side by side, see key specs and what's in the box at a glance, and spot price drops on items they saved. Launch and deal countdowns appear only when you set a date.

Circuit uses custom blocks, so it comes with the Business plan. The Essential style works on every plan.
