ArangoDB database is an open-source NoSQL solution with a flexible data model for documents, graphs, and key-values.



nebula graph is described as 'Nebula Graph is an open-source graph database capable of hosting super large-scale graphs with billions of vertices (nodes) and trillions of edges, with milliseconds of latency. It delivers enterprise-grade high performance to simplify the most complex data sets imaginable into' and is an app. There are more than 10 alternatives to nebula graph for a variety of platforms, including Linux, Mac, Windows, SaaS and Web-based apps. The best nebula graph alternative is ArangoDB, which is free. Other great apps like nebula graph are neo4j, FalkorDB, Amazon DynamoDB and QLever.
