About
Harper is an in-process runtime that combines a database, REST API layer, caching, real-time pub/sub, vector search, and blob storage into a single deployable unit. Developers define their schema in GraphQL and instantly get a full REST and GraphQL API with no controllers, migrations, or ORMs required. It supports deployment to a distributed edge network with a single CLI command.
Problem
Developers must stitch together multiple services (database, cache, API framework, vector DB, file storage, real-time broker) just to build a backend, adding complexity and latency.
For
backend developers and fullstack engineers building production apps or AI agents
How it works
Harper reads a GraphQL schema file to auto-generate REST and GraphQL APIs, handles caching, pub/sub, vector indexing, and blob storage in-process, and deploys the entire backend to a distributed fabric network via a single CLI command.
