Harper

Harper builds a fused technology platform designed for distributed computing, targeting developers who demand both simplicity and extreme performance. The company's work sits at the intersection of distributed computing, in-memory computing, database technology, caching, application runtime, and messaging systems - consolidating disciplines that have traditionally required separate, complex stacks.

The Harper Platform is an open-source Node.js performance platform that unifies database, cache, application, and messaging layers into a single in-memory process. By eliminating serialization overhead and replacing traditional architectures, it achieves data access in approximately one millisecond and delivers up to 85% fewer LLM and origin calls at scale. This architectural approach represents a significant departure from conventional distributed systems design, where multiple discrete services introduce latency and operational complexity.

For engineers and architects working on performance-critical distributed systems, Harper offers a technical foundation that compresses what is typically a multi-layer infrastructure problem into a unified runtime. The platform's open-source nature provides transparency and extensibility for teams building at scale.
