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.
HASH
HASH is an open-source platform that models an organization with a knowledge graph and a process graph. The continuously updated model supports analytics, workflow automation, what-if simulations, AI agents, and detailed access governance. HASH can ingest connected applications and structured data, infer entities from unstructured material, and passively collect selected web information. Its bitemporal graph records transaction time and decision time, letting users inspect earlier states and provenance without overwriting records. Flows combine triggers, actions, filters, and waits and can run manually, automatically, or programmatically. Agents can answer questions and take actions. Integrations include Slack, Google Drive, Gmail, Notion, GitHub, SAP S/4HANA, Snowflake, and Postgres. Two-way synchronization is available where supported; some services allow only read-only sync or one-time imports. A browser extension can collect selected browsing information, let agents access sites for users, and launch flows. HASH is offered through web, API, browser extension, or self-hosted deployment. The free plan includes 10GB storage and 50 entities per manual scraping job. Plus starts at $20 a month when billed annually.
