Harper eliminates the complexity typically synonymous with distributed services by combining an ultra-fast document data store, in-memory cache, real-time message broker, and your application components into a single distributed technology. When clustered and geo-distributed, Harper nodes instantly synchronize data creating a real-time service fabric, ensuring low-latency in-region responses for clients worldwide. In addition to massive cost savings at scale, Harper’s REST, GraphQL, SQL, and real-time interfaces make light work of servicing frontend requirements. Install and manage on your hardware with npm, or have us host your services with Harper Cloud. For questions, reach us at hello@harperdb.io.
Every Installation of Harper can be administered online using Harper Studio. This web-based interface provides you the ability to set up new schemas and tables, configure users and roles, manage data replication, and purchase and deploy enterprise licenses.
