In their own words
LinkedDataHub
LinkedDataHub is an open-source, low-code platform for managing data, creating visualizations, and building applications on RDF knowledge graphs. It can also operate as an RDF-native content management platform. The interface includes UI components, SPARQL templates for creating and editing content, and SPIN and SHACL constraints for validating incoming data. CSV and RDF imports are supported, with SPARQL CONSTRUCT used for mapping or transformation. Authentication supports WebID and OpenID Connect with Google and ORCID. WAC permissions cover read, write, append, and control access. Git-backed document history is available through Memento. The platform exposes a SPARQL endpoint and read-write Linked Data API, serving documents as HTML or RDF from the same URIs. It uses Apache Jena Fuseki by default, supports compatible SPARQL 1.1 triplestores, and runs locally with Docker Compose. The project is self-hosted under Apache 2.0.
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.
