HyperGraphDB vs TerminusDB
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.
Free plan LinuxSelf-hostedWindows
HyperGraphDB is aimed at developers who want an embedded hypergraph model rather than a client/server database. Its Java API, Berkeley DB storage and optional peer-to-peer features define the deployment approach.

Choose TerminusDB if your work needs a schema-enforced document graph with Git-like version control, transactional commits, and multiple query interfaces. Look elsewhere if RDF/SPARQL support is required or if your priority is relational analytics, mature ORMs, or a very large extensions ecosystem.
