JanusGraph

JanusGraph, an open-source graph database with an MIT license, is suitable for organizations requiring a no-fee solution for either cloud or self-hosted deployments. Its design supports scenarios where a flexible, self-managed graph database is preferred.

However, teams prioritizing commercial support or a tool with a higher web presence might find its not-in-top-1M web rank a concern. For those seeking an alternative open-source graph database, Memgraph is also available in our index.
