In their own words
Oxigraph
Oxigraph is a free graph database and RDF/SPARQL toolkit available for Linux, web, API, and self-hosted use. It implements SPARQL 1.1 Query, Update, and Federated Query, and handles RDF formats including Turtle, TriG, N-Triples, N-Quads, RDF/XML, JSON-LD, and N3. The project provides a Rust library, standalone Rust crates, Python bindings, JavaScript bindings, and a command-line tool. That CLI can start an HTTP server implementing the SPARQL 1.1 Protocol and Graph Store Protocol. By default, the server listens on localhost:7878 and offers a YASGUI-based HTML interface for running SPARQL requests. REST endpoints support queries, updates, and RDF dataset access. Installation options include Cargo, Docker, PyPI, conda-forge, and prebuilt binaries. Pyoxigraph supplies in-memory and disk-based stores, and oxrdflib connects rdflib stores to Pyoxigraph. Storage is based on RocksDB, and licensing is Apache 2.0 or MIT.
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.
