Compared to classic relational databases (PostgreSQL,MySQL), Neo4j provides a performance boost regarding both resource usage and query speed.

This is mainly due to its simpler structure, Neo4j using simple graph trees to store data and relations between it, instead of clunky and sometimes fixed relational table.

Neo4j is the most popular graph database in use today. Other Neo4j alternatives include ArangoDB, Titan or OrientDB.

Neo4j is offered in 3 versions, all open sourced, but with different licensing.

All versions are offered within one downloadable archive, just make sure to choose the proper one according to your application's licensing model.

All three versions can also be used as a stand-alone graph database server, or as an embeddable component for your applications.
