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 LLM integration. GraphTalker lets users ask questions in natural language and returns verified answers through an iterative agent-driven process. The product lists RDF, OWL, SPARQL, SHACL, Prolog rules, and reasoning, while FedShard provides horizontal sharding and federation across machines. It also supports geospatial, temporal, and social-network analytics, plus integrations with Solr and MongoDB. The Free edition is limited to up to 5 million triples; Enterprise lists unlimited triples and no server limit. The security comparison lists encryption, role-based access control, IP allowlists, and audit logs. AllegroGraph is available for download or cloud hosting, including AWS Marketplace and Azure Marketplace. Although Windows and macOS are listed among the platforms, the server runs natively on Linux x86-64; its documentation recommends a Linux virtual machine or Docker container for Windows or macOS.

Who it is for

It suits teams building Knowledge Graphs or integrating complex data, including the listed pharma, healthcare, Customer 360, and supply-chain use cases. Users on Windows or macOS should note the server’s native Linux requirement.
