Everlane set out to build a best-in-class ecommerce experience—one where every customer sees products, recommendations, and offers tailored to their preferences in real time. This case study from Netlify reveals how the composable web architecture makes that vision possible. Rather than relying on monolithic platforms that slow down iteration, Everlane adopted a headless approach powered by Netlify's edge infrastructure, enabling them to deploy personalized experiences globally with sub-second load times. The video walks through the architectural decisions, API strategy, and integration patterns that allow marketing and product teams to run personalization experiments without engineering bottlenecks. It covers how content is served at the edge, how personalization logic integrates with CDP data, and how Everlane measures impact across customer segments. For product leaders, developers, and ecommerce operators, this is a real-world blueprint for moving beyond generic storefronts to true 1:1 digital commerce—all while maintaining speed, uptime, and developer velocity.
