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.
Memgraph
Memgraph is an in-memory graph database platform for graph computations on streaming data. It supports Cypher and lists Kafka, Pulsar, and Redpanda as streaming connectors. Its free Community Edition includes ACID transactions, on-disk persistence, high-availability replication, and vector search. MAGE adds more than 60 graph algorithms, with integrations for NetworkX, igraph, and cuGraph. Memgraph Lab provides a visual interface for querying, managing, importing, and visualizing graph data; it also supports natural-language queries through GraphChat. Programmatic drivers are listed for Python, C/C++, Rust, Node.js, C#, Go, Haskell, Java, JavaScript, PHP, and Ruby. Enterprise features include role- and label-based access controls, SSO, LDAP/PAM authentication, TLS encryption in transit, audit logging, failover, replication, disaster recovery, no-downtime updates, and monitoring. Community support is available through Discord; Enterprise includes direct engineering support through a dedicated Slack channel. Memgraph Cloud is managed and hosted on AWS in six regions, with instances from 1 GB to 32 GB RAM. Community Edition is free forever. Enterprise plans have unlisted prices that scale by memory capacity or graph data capacity, depending on the edition, and the Enterprise trial lasts 30 days.
