CognoDB vs NebulaGraph

Both stand on graph databases. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

CognoDB

Free plan APISelf-hostedWeb

CognoDB combines Cypher and Bolt compatibility with managed operations and daily encrypted snapshots. It may not fit projects that require vector search or a self-hosted deployment.

Visit CognoDB

NebulaGraph offers graph query, vector search and multiple deployment options, with a free open-source edition and a 14-day Cloud trial. Buyers should compare edition and plan limits, particularly the subset of core features and the Standard plan’s lack of high availability.
