About Apache AGE

Apache AGE, short for A Graph Extension, is an extension for PostgreSQL that adds a graph database to an existing relational database. The principle is a single storage layer that handles both the relational and the graph data model, so you can use ANSI SQL together with the openCypher graph query language in the same database.

It is inspired by AgensGraph, the multi-model PostgreSQL fork from Bitnine, and positions itself for graph processing and analytics on top of relational data. Repository topics mention analytics, multi-model database and PostgreSQL extension, and the latest release tags support recent PostgreSQL versions. The extension is written mainly in C.

Apache AGE is an Apache Software Foundation project under the Apache-2.0 license. You install it into your own PostgreSQL servers, and some managed Postgres providers also offer it. It suits teams that want to add relationship-heavy queries such as social graphs, recommendations and lineage to Postgres without adopting a separate graph database.
