Harper is a unified runtime designed to simplify backend development by consolidating data storage, caching, API generation, and real-time messaging into a single multi-threaded process. It supports schema-driven development, vector search for AI agents, and global replication. By eliminating the need for separate infrastructure like Redis, Kafka, or dedicated API servers, Harper reduces latency and operational complexity for full-stack applications and agentic workflows.
