Summary

Fluree DB is a graph database built on RDF triples, combining temporal history, verifiable transactions, search, and fine-grained access controls in a single binary. Each transaction is cryptographically signed and added to an immutable ledger, and the full history can be queried. Its search capabilities include full-text and vector search alongside graph data and time-travel queries. Attribute-, role-, and relationship-based policies are evaluated at query time down to individual triples. Fluree is based on W3C standards such as JSON-LD, RDF, SPARQL, OWL, and SHACL; listed capabilities include SPARQL 1.1, reasoning, RDF-star, and federated queries. Interfaces include SPARQL, FlureeQL, REST, MCP server configuration, LangChain, and LlamaIndex; 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. Free options include FlureeDB Open Source and Fluree AI. The Business Source License 1.1 applies, with commercial licensing available by contacting Fluree.
