| Deployment | The server runs natively on 64-bit Linux; Windows and macOS users can use hosted service, Docker, WSL or a Linux virtual machine. | The quickstart runs TerminusDB in Docker, and the documentation also describes building from source on Linux or macOS and running it on Kubernetes. |
| Integrations | Documented integrations include MongoDB, Solr, Kubernetes, Docker, AWS and Azure marketplaces, plus Prometheus/Grafana monitoring. | Its GraphQL interface works with Apollo, urql, Relay, and other GraphQL clients; official client libraries are available for TypeScript/JavaScript and Python, with Rust also documented. |
| Intended users | The maker identifies use cases including Neuro-Symbolic AI, pharma discovery, healthcare, Customer 360, supply-chain logistics, Knowledge Graphs, and Data Fabric. | The documentation describes TerminusDB as designed for developers and data engineers working with auditable data lineage, complex domain models, collaborative data workflows, or evolving structured content. |

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.
TerminusDB
TerminusDB is a free, open-source document graph database for JSON documents stored in a schema-enforced graph. It adds Git-like version control for data, including branching, diffing, merging, cloning, synchronization, and time travel. Commits are ACID transactions, and every write receives schema validation. Developers can use the HTTP document API, GraphQL, or WOQL, a Datalog-based query language. GraphQL works with Apollo, urql, Relay, and other clients; official libraries cover TypeScript/JavaScript and Python, with Rust documented. Role-based access control uses users, roles, capabilities, and resource scopes. Deployment documentation covers Docker, Linux or macOS source builds, and Kubernetes. DFRNT provides cloud hosting instances, while community support is available through Discord and GitHub. TerminusDB supports ontology modeling, semantic reasoning, graph visualization, and imports from CSV, JSON, JSON-LD, RDF/XML, and Turtle. It does not support RDF/SPARQL.
