In their own words
GraphDB
GraphDB is an RDF and SPARQL semantic graph database for storing data and performing inferencing in the Graphwise AI Platform. It supports SPARQL 1.1, RDF4J compatibility, RDFS and OWL 2 RL and QL rulesets, federated queries, and RDF-star. Its real-time forward-chaining reasoning operates across datasets, and the product page describes native GraphRAG and LangChain integration. GraphDB can run as a desktop or standalone server application, be self-hosted, or be deployed on AWS and Azure; downloads are listed for Windows, macOS, Linux, and a platform-independent distribution. The Free edition includes a Lucene connector, one parallel query, and up to five repositories; GraphDB 11 and later requires a free license. Enterprise supports multiple cores, unlimited repositories, high-availability clustering, and connectors for Elasticsearch, OpenSearch, Solr, and Kafka. Free is on-premise only with community support. Enterprise includes SLA support and is licensed per server CPU core, with each cluster node licensed separately. Free costs nothing; Enterprise pricing is on request.
Mulgara
Mulgara is a free, open-source semantic store for metadata and relationships. It records information as RDF subject-predicate-object statements and supports SPARQL and TQL queries. Listed capabilities include native RDF, reasoning, federated queries, full-text search, datatypes, multiple databases per server, large storage, streamed results, and on-disk joins. The project also lists transactions, clustering, store-level fail-over, permanent integrity, low memory requirements, and multi-processor support. Connectivity options include Sesame SAIL API, JRDF, SOAP, HTTP, and a Software Developers Kit. A standalone server provides a Web UI, SPARQL and TQL HTTP services, REST interfaces, web services, and a tutorial; TQL permits CRUD operations while SPARQL is query-only. Mulgara can run standalone or as a WAR in a Java web server. It supports RDF/XML, N-Triples, and N3, and imports compressed or uncompressed files. The latest named release is v2.1.13. Source code uses Open Software License v. 3.0.
