In their own words
qEndpoint
qEndpoint is a free, open-source RDF triple store for self-hosted linked-data workloads. It supports full-text search, GeoSPARQL, and SPARQL 1.1, either as a standalone endpoint or as a dependency. A graphical interface lets users write and run SPARQL queries, while a RESTful HTTP API handles queries. Datasets can be uploaded in RDF4J-supported formats, including RDF/XML, Turtle, N-Triples, N-Quads, JSON-LD, TriG, and TriX. Result formats include JSON, XML, and Binary RDF. Docker images are available for qEndpoint and for a Wikidata-indexed variant supporting wikidata_truthy and wikidata_all datasets. The Docker setup defaults to 6G memory; large datasets are discouraged below 4G, and Wikidata-all requires at least 10G. Installation documentation covers Scoop, Homebrew, and a CLI ZIP release. The project describes Wikibase use and is licensed under GNU GPL v3.
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.
