Faster Websites Drive More Revenue

Improve Core Web Vitals (especially LCP) to drive conversion and revenue. Harper provides you with the tools and insights to achieve blazing-fast performance.
Modern e-commerce systems are adaptable, distributed, and composable—but at scale, off-the-shelf components fall short. Over the last 5 years, many developers have started to explore the “headless” direction, separating the front and back ends of their e-commerce platforms to deliver more manageable solutions. However, this option falls short for most large-scale commerce sites, which require even more detailed control and low-latency performance, given the intense requirements of their systems. These teams have begun looking for composable low-latency solutions, and in this instance, Harper is unbeatable.

How Much More Could You Earn?

Web performance is a business driver. Faster load times mean happier users, better conversion rates, and more revenue. Use the sliders on our interactive ROI calculator to estimate the additional revenue you could earn by reducing the time to Largest Contentful Paint (LCP) on your website.
Research by Deloitte Digital (“Milliseconds Make Millions”) suggests that improving page load time by just 100 milliseconds can increase conversion rates by approximately 2%. This figure is an estimate based on the extrapolation of that number and should be interpreted as a potential uplift rather than a guaranteed outcome. Actual results may vary.

4 Ways to Boost Web Performance (Without a System Migration)

Most CDN and edge solutions focus on partial wins. Harper’s platform unlocks full-page performance improvements at a scale and logic depth others simply can’t match.

From Chaos to Control: Simplifying E-Commerce Infrastructure

E-commerce architecture is built with components—databases, caches, messaging, and applications. But when these elements exist as separate, loosely connected processes, they introduce unnecessary complexity, latency, and maintenance overhead.

Unifying E-Commerce for Seamless Scalability

Fused technology reimagines this paradigm by unifying all core functions into self-contained, high-performance components that operate across geographies. Instead of juggling multiple infrastructure layers, you get a streamlined system that is easier to deploy, manage, and scale—without sacrificing flexibility or control.With a component-driven architecture, you can build and optimize your stack using familiar technologies, like JavaScript, without compromising performance.
