Ontop vs TypeDB
Both stand on knowledge graph software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan APILinuxMac+3
Choose Ontop if you need an open source way to expose relational databases as virtual knowledge graphs and query them with SPARQL. Its database driver setup and generic JDBC caveats may be a concern for configurations without a documented dialect-specific connector; users needing lenses in Protégé will also need another editing approach.
