Fluree Labs — Build in Your Browser

Ontology Builder

Visually design and export JSON-LD ontologies for your knowledge graph. Drag-and-drop classes, properties, and relationships. Export as JSON-LD, Turtle, or OWL.

Knowledge Graph Builder

Build and explore knowledge graphs interactively. Add entities, create relationships, run queries, and visualize your graph — all in the browser.

Chat with Our Codebase

Ask questions about Fluree’s source code and get AI-powered answers grounded in the actual codebase. Understand architecture decisions and explore the code without cloning.

Benchmarks

LLM Accuracy Benchmark

Comparing GraphRAG vs traditional vector RAG — measuring answer accuracy, hallucination rates, and provenance quality across LLM-powered Q&A.

4× improvement in zero-shot accuracy. 95%+ with semantic enrichment.

RDF Performance Benchmark

Performance benchmarks for Fluree’s SPARQL query engine — insert throughput, query latency, and scalability across standard RDF workloads.
