Harper is a modern web platform built for latency-sensitive applications, combining database, cache, messaging, and application logic into a single, distributed runtime. By eliminating the traditional layers of infrastructure, Harper simplifies development, reduces costs, and delivers ultra-low-latency performance at scale. Its unified architecture enables real-time responsiveness and seamless global data synchronization, making it ideal for high-throughput applications.
Today’s SaaS platforms are buried under layers of infrastructure: separate services for databases, caches, queues, APIs, and edge delivery. It’s complex, brittle, expensive, and slow to evolve.
Harper’s Paradigm Shift
Harper integrates the database, cache, messaging, and application functions into a single runtime designed for deployment and synchronization across regions. The distributed yet unified architecture creates highly efficient services that deliver extremely high-throughput at ultra-low-latency. Creating easy-to-manage services that can scale to efficiently manage 100s of terabytes of data.
Unified Architecture – One binary handles data, caching, messaging, and logic, simplifying development.
Distributed by Design – Deploy globally and synchronize data across regions in milliseconds.
Higher Throughput by Design – Harper eliminates network hops and intermediary serialization steps, freeing bandwidth for more RPS with less overhead.
Low-Latency In-Process APIs – Access your data directly through REST, GraphQL, or custom endpoints, running inside the same process as your persistent and in-memory data stores.
Boilerplate Code Eliminated – Define data schemas with an @export directive to auto-generate REST and real-time endpoints (MQTT, WebSocket).
Real-Time Native – Data updates instantly trigger messages, no separate broker or handler required.
Proven Impact
