A distributed, scalable, lightning-fast graph database
Nebula Graph is an open-source graph database capable of hosting super large scale graphs with dozens of billions of vertices (nodes) and trillions of edges, with milliseconds of latency.
Compared with other graph database solutions, Nebula Graph has the following advantages:
- Symmetrically distributed
- Storage and computing separation
- Horizontal scalability
- Strong data consistency by RAFT protocol
- SQL-like query language
- Role-based access control for higher level security
After v2.5.0, we use Nebula repo.
Read the Getting started article for a quick start.
Please note that you must install Nebula Graph by installing source code, rpm/deb packages or docker compose, before you can actually start using it. If you prefer a video tutorial, visit our YouTube channel.

Nebula Graph is under Apache 2.0 license, so you can freely download, modify, and deploy the source code to meet your needs. You can also freely deploy Nebula Graph as a back-end service to support your SaaS deployment.
In order to prevent cloud providers monetizing from the project without contributing back, we added Commons Clause 1.0 to the project. As mentioned above, we fully commit to the open source community. We would love to hear your thoughts on the licensing model and are willing to make it more suitable for the community.
