In their own words
GraphDB
GraphDB is a semantic graph database that uses RDF and SPARQL to connect business data and support real-time AI insights. It applies reasoning and semantic search to connected information. Free and Enterprise editions support RDF 1.1, SPARQL 1.1, RDF-Star, SPARQL-Star, and reasoning for RDFS, OWL 2 RL and OWL 2 QL. Listed AI capabilities include GraphRAG, MCP support, no-code RAG chat in Workbench, precision entity linking and natural-language graph queries from LangChain. Integrations include MongoDB, Kafka, JDBC, GraphQL, SQL-accessible data virtualization, and connectors for Lucene, Elasticsearch and Solr. GraphDB Free has a single-core license. Starting with version 11.0.0, every edition requires a valid license, which can be requested for free. Enterprise supports twelve or more cores and features such as parallel query processing, cluster failover, synchronization and load balancing. Enterprise is available on-premise or as a 12-core cluster SaaS through AWS Marketplace and Microsoft Azure Marketplace. GraphDB supports Linux, macOS, Windows, web and self-hosted deployments, with API access.
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.
