Harper's Open Source Move to Accelerate High-Performance Web Development and Innovation

Harper Open Sources its Composable Application Platform

In a bold move to champion open collaboration and innovation, Harper has unveiled its decision to open source its composable full-stack web application platform at the JSConf North America 2025 event. This announcement heralds a significant step forward in democratizing access to their advanced web technology, aimed at enhancing the performance of data-intensive applications.

Harper's composable platform merges critical components such as databases, caching, messaging, and Node.js runtime into a singular server-side process. This integrated approach promises unparalleled speed and efficiency, making it ideally suited for high-performance web applications requiring low latency. By releasing this powerful platform to the community, Harper seeks to proliferate its adoption among Node.js developers and cultivate an ecosystem of collaborative contributions.

The impetus behind this open-source initiative comes amidst strong enterprise traction for Harper's technology. The platform is already handling an impressive share of global e-commerce transactions, effectively powering approximately two percent of online purchases worldwide. Customers utilizing Harper's architecture have reported staggering improvements in performance metrics, enabling server response times of less than one millisecond—a feat that typically requires over 100 milliseconds with conventional stacks. Furthermore, web pages built on this platform load up to seven times faster, translating to substantial user engagement and improved conversion rates for Fortune 100 retailers and other high-traffic websites.

At the heart of these advancements is Harper’s cloud and edge-native unified architecture. This innovative design simplistically integrates various layers of the web stack into one streamlined process. By doing so, Harper effectively minimizes the delays usually attributed to data transit and system serialization, thereby achieving low response times even across distributed servers.

Harper plans to release the source code under the Apache 2.0 license, a strategic choice that maximizes flexibility for developers and organizations. This openness allows any entity to deploy Harper's engine in their preferred environments, seamlessly integrate it with existing systems, and create tailored commercial solutions.

Stephen Goldberg, CEO and co-founder of Harper, emphasized the value of this decision, stating, "Open sourcing our technology is a way for us to collaborate and build alongside the developer community, particularly the Node.js community, which has played a vital role in shaping our platform. By putting Harper in the hands of skilled developers worldwide, we invite them to contribute to the future of high-speed, edge-native applications." He expressed excitement about the potential innovations fostered by the community, reinforcing Harper's commitment to openness and performance.

This open-source release is a defining moment for Harper, solidifying its goal to spur innovation through community engagement. The company aims to expand the frontiers of edge computing and distributed web applications, driven by ideas and feedback generated from its users.

Harper is poised to continue offering enterprise-grade support and managed services tailored for organizations needing production-level assistance, hence guaranteeing both community members and enterprise clients benefit from its evolution.

Developers interested in utilizing Harper's platform can access the GitHub repository, run the engine within their environments, and join community forums and Discord channels for collaboration. For more documentation and examples, interested parties can visit www.harpersystems.dev.
