Cupertino, California, United States
What it is
NebulaGraph is a distributed graph database for storing and querying complex connected data. It is designed for scale and millisecond responses to complex queries; NebulaGraph says it can store and process graphs with trillions of edges and vertices. It supports nGQL and openCypher compatibility, with native ISO-GQL support in Enterprise v5.0. Native vector search combines graph structures with unstructured data. Deployment options include on-premises, public cloud and hybrid environments, and NebulaGraph Cloud can deploy clusters on Microsoft Azure, AWS and Google Cloud Platform. Official ecosystem tools include Java, Python, C++ and Go clients, plus Spark and Flink connectors. NebulaGraph Studio is a web-based tool for creating schemas, importing data, writing nGQL queries and exploring graphs. Cloud features include Private Link, role-based graph-space access, Raft-based redundant backups across server rooms in the same city, and snapshots for point-in-time restoration. The open-source edition is free under Apache 2.0 and offers a subset of core features. A 14-day Cloud trial includes one instance with 2 vCPUs, 4 GB RAM and 10 GB storage, with no payment information required.
