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.
Mendix
Mendix is a low-code platform for building, running, and orchestrating apps and agents for a hybrid workforce. In Studio Pro, teams model application logic, data, workflows, and user experience visually, while retaining the option to add custom code. Its AI capabilities span planning, generation, deployment, and operations, and it can connect external language models, agents, knowledge bases, and tools. The Mendix Connect Catalog can include connectors to enterprise data sources such as Siemens Teamcenter, SAP, and Mendix applications. Applications can be deployed to public cloud or on-premises, including air-gapped environments. Listed capabilities include mobile publishing, a built-in database, user authentication, and API integrations. The free package allows unlimited users and one deployment environment per application, but includes neither product support nor guaranteed availability. Standard pricing is $1,090 a month for One App or $2,725 a month for Unlimited Apps; cloud deployment may cost extra. Mendix was founded in Rotterdam in 2005 and says it was acquired by Siemens in 2018.
