AionDB

PostgreSQL-compatible SQL, graph, and vector database in one engine — stop splitting application data across three stores

Serviceprototypefreeglobal

A source-available database engine, AionDB keeps tables as the source of truth while adding graph relationships and fixed-dimension vector columns with HNSW indexes in the same catalog, accessible via the PostgreSQL wire protocol so existing drivers and ORMs work. It addresses the operational and synchronization costs of running separate relational, graph, and vector stores for teams building AI features over operational data. Released under a BSL that converts to Apache 2.0, it is currently in alpha and not a drop-in replacement for mature production databases.
