In their own words
Eclipse RDF4J
Eclipse RDF4J is a modular Java framework for parsing, storing, querying, and reasoning over RDF data. It supports SPARQL 1.1 query and update, and its API can access remote RDF repositories in the same way as local ones. Supported formats include RDF/XML, Turtle, N-Triples, N-Quads, JSON-LD, TriG, and TriX. Storage options include a transactional in-memory store with optional disk persistence and a transactional Native Store aimed at medium-sized datasets around 100 million triples. Extensions add full-text search, RDFS inferencing, rule-based reasoning, SHACL and SPIN validation, and geospatial queries. The SDK bundles libraries, Server, Workbench, Console, and Javadoc API; Workbench includes a web interface with a SPARQL editor. Developers can use Maven artifacts or download an SDK zip or onejar. RDF4J is free under the Eclipse Distribution License, version 1.0. The latest stable release, 6.1.0, requires Java 25 or newer. The project describes its core databases as mainly intended for small to medium-sized datasets and notes third-party stores may scale further or offer additional features.
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.
