In their own words
AllegroGraph
AllegroGraph is a semantic graph database for building knowledge graphs and integrating complex data. It combines graph data with vector storage, symbolic reasoning and large language model integration. GraphTalker accepts natural-language questions about knowledge graphs and returns verified answers through an iterative, agent-driven process. Supported technologies include RDF, OWL, SPARQL, SHACL and Prolog rules, alongside reasoning. FedShard provides horizontal sharding and federation, combining query results from multiple machines. Analytics include geospatial, temporal and social-network analysis. Listed integrations include Solr, MongoDB and REST-based clients for Java, Python, RDF4J, Apache Jena and Lisp. The Free edition costs nothing and is limited to up to 5 million triples. Enterprise has no listed price and specifies unlimited triples with no server limit. AllegroGraph is available as a download or through cloud hosting, including AWS Marketplace and Azure Marketplace. The server runs natively on Linux x86-64; Windows or macOS use is recommended through a Linux virtual machine or Docker container.
Virtuoso Universal Server
Virtuoso Universal Server is a multi-model database management system and HTTP-based application server for working with data from different sources. It supports relational SQL data, RDF, SPARQL, XML, JSON, and web services. A virtualization layer lets users query multiple sources through a unified database view, with connections through HTTP, ODBC, and JDBC. Listed standards include SQL, SPARQL, GraphQL, and RDF. The product has open-source and commercial licenses; the open-source version is under GPL. Commercial licensing adds advanced security, custom reasoning and inference, high-availability replication, and professional support. The maker describes fine-grained attribute-based access controls and lists encryption at rest as a commercial feature. Deployment options include Linux/Unix, Docker, Windows, and macOS installations, as well as on-premises/BYOL, AWS, and Azure. The maker lists data integration, governance, knowledge management, data productization, and AI-driven customer support as typical uses. Personal, Developer, and Project workstation licenses cost $99.99 as a one-time purchase, $199, paid once, and $499, paid once, respectively. OpenLink Software, the privately held maker, was founded in 1992.
