Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureHave you ever visited a website but navigated away because the product page wasn't loading fast enough? So we built this app to solve that problem & help merchants prevent lost sales. When your customers move their mouse cursor over a link, we tell their browser to pre-load that page in the background. This results in much faster loading times.
Keep your store speed fast, easy to discover, and ready for AI / LLMs. Thunder continuously monitors how real shoppers experience every page and proactively optimizes slow pages, images, CSS, navigation, and third-party scripts. It identifies delayed clicks, layout shifts, broken links, and hard-to-crawl content, then prioritizes what needs attention.
