Protocols PostgreSQL wire

AgensGraph is a PostgreSQL fork; its JDBC driver connects on the standard Postgres port (5432) and default docker mapping confirms this.

License Apache-2.0

LICENSE file in the current maintainer's repo (post Bitnine, now skaiworldwide-oss) is Apache License 2.0; confirms current value.

  • Agens Graph Copyright (c) 2014-2017 Bitnine, Inc. All Rights Reserved. Licensed under the Apache License, Version 2.0 (the "License");
    LICENSE (skaiworldwide-oss/agensgraph) · reviewed 2026-08-02

Released 2016-11

Corrected from 2017-01, which was the 1.0 GA date. Bitnine publicly demoed AgensGraph Community Edition 0.9 at PGConf Silicon Valley 2016 (Nov 14-16, 2016), which counts as the first public preview.

Language C

AgensGraph is a fork of PostgreSQL (itself written in C); GitHub's own language detection agrees.
