| High availability | Enterprise features include multi-master replication, warm standby, online backups and point-in-time recovery. | RDFox can replicate knowledge and data changes across multiple servers for service continuity during an outage. |
| Integrations | Documented integrations include MongoDB, Solr, Kubernetes, Docker, AWS and Azure marketplaces, plus Prometheus/Grafana monitoring. | RDFox was made available on AWS Marketplace through a DataLens partnership with pay-as-you-go deployment and connectors for SQL, CSV, XML, JSON, REST and unstructured data. |
| Notable news | Franz announced AllegroGraph 9.0 with GraphTalker on May 4, 2026. | LinkedIn posts announced an RDFox Live event on 29 September 2026 featuring a major new visual collaborative platform addition. |
| Praise: support | A G2 reviewer called the technical-support team exceptionally responsive, thorough and insightful. | Several G2 reviewers describe Oxford Semantic Technologies support as responsive, technically strong and quick to fix issues. |
| Product | AllegroGraph is a horizontally scalable semantic graph database for building Knowledge Graphs and integrating complex data. | RDFox is a main-memory, scalable centralized data store for RDF graph data queried with SPARQL 1.1. |
| Rating on G2 | 5 out of 5 from 3 eligible reviews; G2 says there are too few reviews for buying insight. | 4.8 out of 5 from 14 reviews |
| Security | The editions comparison lists triple-level security, encryption in transit and at rest, encrypted backups, role-based access control, IP allowlists, and audit logs. | RDFox v7.0 added encryption at rest and client-certificate authentication using mutual TLS for endpoint and remote-shell requests. |

In their own words
AllegroGraph
AllegroGraph is a semantic graph database for building knowledge graphs and integrating complex data. It combines graph data with vector storage, symbolic reasoning and large language model integration. GraphTalker accepts natural-language questions about knowledge graphs and returns verified answers through an iterative, agent-driven process. Supported technologies include RDF, OWL, SPARQL, SHACL and Prolog rules, alongside reasoning. FedShard provides horizontal sharding and federation, combining query results from multiple machines. Analytics include geospatial, temporal and social-network analysis. Listed integrations include Solr, MongoDB and REST-based clients for Java, Python, RDF4J, Apache Jena and Lisp. The Free edition costs nothing and is limited to up to 5 million triples. Enterprise has no listed price and specifies unlimited triples with no server limit. AllegroGraph is available as a download or through cloud hosting, including AWS Marketplace and Azure Marketplace. The server runs natively on Linux x86-64; Windows or macOS use is recommended through a Linux virtual machine or Docker container.
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.
