About HarperDB

HarperDB, which now trades as Harper, offers a runtime where the database, cache, application code and messaging all live together. Data and code share one process instead of being split across separate products.

What Harper offers

  • Unified data and application layer: according to Harper, merging these layers cuts latency and cost versus wiring up a separate database, cache and app server.
  • Fast data retrieval: around a millisecond in typical use, according to the company.
  • AI agent support: agent memory, embeddings and tool interfaces share the runtime, letting an agent retrieve context without a separate vector database.
  • Streaming protocols: MQTT, WebSocket and server-sent events are built in next to the data, so applications can react to record changes without a separate message queue.
  • Geo-distributed replication: keeps state close to users across regions.
