ONgDB review
A native graph database for connected data, with a choice of self-hosting or managed cloud.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ONgDB is an open-source native graph database maintained by the Graph Foundation and offered by GraphGrid, Inc. It represents connected data as nodes and relationships, with ACID transactions, high-availability clustering and access control. Teams can run it on Windows, macOS or Linux as a standalone or embedded server, or choose managed cloud deployment. That combination suits organizations that want graph storage with self-hosting flexibility, as well as teams looking for a hosted, single-tenant option.
The query language is Geequel, described as declarative. Other listed capabilities include scale-out in-memory read sharding and secure user access control. For managed cloud, the offering includes dedicated VPCs and VPC peering, along with cloud monitoring, logs and plugin installation. These features make deployment and operational controls relevant considerations for teams evaluating a hosted graph environment. The listed platform details focus on graph storage, transactions and deployment; buyers should assess whether Geequel and the available ecosystem fit their application before adopting it.
ONgDB software itself is free and open source, while managed cloud and support are paid services. Published cloud examples use AWS instance types such as t3.small, t3.large, c5.xlarg, m5.xlarge and m5.2xlarge; the estimates cover 30 days, with storage and data transfer billed separately. Support channels include documentation, email, phone and community, with 24/7 support listed. Choose ONgDB if native graph storage and the choice between self-hosting and managed cloud matter most. Consider alternatives if your decision depends on a broader documented set of query languages, integrations or graph algorithms.
