In their own words
GraphDB
GraphDB is a semantic graph database that uses RDF and SPARQL to connect business data and support real-time AI insights. It applies reasoning and semantic search to connected information. Free and Enterprise editions support RDF 1.1, SPARQL 1.1, RDF-Star, SPARQL-Star, and reasoning for RDFS, OWL 2 RL and OWL 2 QL. Listed AI capabilities include GraphRAG, MCP support, no-code RAG chat in Workbench, precision entity linking and natural-language graph queries from LangChain. Integrations include MongoDB, Kafka, JDBC, GraphQL, SQL-accessible data virtualization, and connectors for Lucene, Elasticsearch and Solr. GraphDB Free has a single-core license. Starting with version 11.0.0, every edition requires a valid license, which can be requested for free. Enterprise supports twelve or more cores and features such as parallel query processing, cluster failover, synchronization and load balancing. Enterprise is available on-premise or as a 12-core cluster SaaS through AWS Marketplace and Microsoft Azure Marketplace. GraphDB supports Linux, macOS, Windows, web and self-hosted deployments, with API access.
RDFox
RDFox is a main-memory data store for centralized RDF graphs, queried with SPARQL 1.1. It represents rules and ontological axioms with Datalog, OWL 2 and SWRL, and updates rule consequences as data changes; it can process 2–3 million new-fact inferences per second. Its supported knowledge-graph technologies include RDF, SPARQL 1.1, Datalog, SWRL, OWL 2 RL and SHACL. Java applications can connect through a native API, or RDFox can run as a standalone server through a REST API. Import and export formats include CSV, JSON, N-Triples, Turtle, TriG and OWL 2 Functional-Style Syntax. It can replicate knowledge and data changes across servers to maintain service during an outage, and deployments are described for cloud, on-premises, on-device and edge use. RDFox runs on Linux, macOS and Windows. Security features include encryption at rest, mutual-TLS client-certificate authentication and OpenID Connect single sign-on. Pricing is on request; the free 30-day evaluation license is restricted to evaluation and non-commercial use.
