The OpenJS Foundation, providing vendor-neutral support for sustained growth within the open source JavaScript community, is excited to welcome Harper as our newest member. Harper joins the Foundation at the silver level.

​Harper is a composable application platform designed to simplify and accelerate the development of data-intensive, latency-sensitive applications. It integrates a high-performance database, application server, caching, and messaging functions into a single runtime, eliminating the need for separate technologies,reducing latency, complexity, and costs.​

Harper is uniquely built entirely in Node.js, making it the only database of its kind. This architecture allows for seamless integration with JavaScript applications and leverages the vast ecosystem of Node.js packages.

“Joining the OpenJS Foundation marks a natural step in Harper’s commitment to the JavaScript community,” said Ethan Arrowood, Senior Software Engineer at Harper. “Our platform is built with Node.js at its core, and we’re excited to collaborate more deeply on open standards, performance optimization, and real-world tooling that supports developers building modern, distributed applications.”

Harper's deep integration with JavaScript technologies, commitment to open-source collaboration, and provision of developer-friendly resources make it a valuable asset to the JavaScript community.​

“We’re excited to welcome Harper to the OpenJS Foundation. Their deep integration with Node.js and dedication to performance and developer experience reflect the values we stand for,” said Robin Bender Ginn, Executive Director, OpenJS Foundation. “We look forward to their contributions as we continue to grow a healthy, vendor-neutral ecosystem for JavaScript and web technologies.”

"Harper joining the OpenJS Foundation is a big win for the Node.js community. Their real-world experience building high-performance, distributed applications on Node.js brings practical insights that can help move the platform forward,” said Matteo Collina, CPC Board Director at the OpenJS Foundation. “It’s great to see more companies turning their success into open source contributions.”
