Fluree DB vs GraphDB

Fluree DB is a graph database for data that needs queryable history, verifiable transactions, and fine-grained access rules. It stores RDF triples and appends each cryptographically signed transaction to an immutable ledger, preserving a full temporal history. Graph data can be queried alongside full-text and vector search, with time-travel queries available. Attribute-, role-, and relationship-based policies are evaluated at query time down to individual triples. Fluree is built on W3C standards including JSON-LD, RDF, SPARQL, OWL, and SHACL; listed capabilities include SPARQL 1.1, reasoning, RDF-star, and federated queries. Interfaces include FlureeQL and REST, plus MCP server configuration, LangChain, and LlamaIndex options. Official SDKs are listed for JavaScript/TypeScript, Python, and Java. It runs as a static binary without a JVM or external dependencies, with Docker, Homebrew, shell, PowerShell, and source-build options. The Open Source and Fluree AI plans are free. The Business Source License 1.1 applies, and commercial licensing is available by contacting Fluree.

GraphDB is an RDF and SPARQL semantic graph database for storing data and performing inferencing in the Graphwise AI Platform. It supports SPARQL 1.1, RDF4J compatibility, RDFS and OWL 2 RL and QL rulesets, federated queries, and RDF-star. Its real-time forward-chaining reasoning operates across datasets, and the product page describes native GraphRAG and LangChain integration. GraphDB can run as a desktop or standalone server application, be self-hosted, or be deployed on AWS and Azure; downloads are listed for Windows, macOS, Linux, and a platform-independent distribution. The Free edition includes a Lucene connector, one parallel query, and up to five repositories; GraphDB 11 and later requires a free license. Enterprise supports multiple cores, unlimited repositories, high-availability clustering, and connectors for Elasticsearch, OpenSearch, Solr, and Kafka. Free is on-premise only with community support. Enterprise includes SLA support and is licensed per server CPU core, with each cluster node licensed separately. Free costs nothing; Enterprise pricing is on request.
