Distributed, open source, massively scalable graph database
JanusGraph is a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine cluster.
JanusGraph is a project under The Linux Foundation, and includes participants from Expero, Google, GRAKN.AI, Hortonworks, IBM and Amazon.
Scalable
Open source
All functionality is totally free. No need to buy commercial licenses. JanusGraph is fully Open Source under the Apache 2 license.
Transactional
