The record

Core database: Fluree Core is a temporal, verifiable, standards-compliant graph database using RDF triples, complete history, integrated search and fine-grained access control in a single binary.
Immutable ledger: Every transaction is cryptographically signed and appended to an immutable ledger, with full temporal history queryable.
Data policies: Attribute-based, role-based and relationship-based policies are evaluated at query time at individual-triple granularity.
Search capabilities: Fluree DB provides full-text and vector search alongside graph data and time travel.
Integrations: Connectors cover PostgreSQL, MySQL, SQL Server, Oracle, MongoDB, Salesforce, HubSpot, ServiceNow, Workday, SAP, Snowflake, Databricks, BigQuery and REST APIs.
Developer interfaces: Fluree provides SPARQL, FlureeQL, a REST API, MCP server configuration, LangChain integration and a LlamaIndex connector.
SDKs: Official SDKs and libraries are listed for JavaScript/TypeScript, Python and Java.
Deployment: Fluree DB is distributed as a single static binary with no JVM or external dependencies, and can run through Docker, Homebrew, shell installation, PowerShell or source builds.
License: Fluree is available under the Business Source License 1.1, with commercial licensing available by contacting Fluree.
Encryption: Managed deployments encrypt data in transit with TLS 1.2+ and at rest with AES-256, and support customer-managed keys through AWS KMS, GCP Cloud KMS and Azure Key Vault.
Compliance: Fluree says its architecture supports SOC 2, ISO 27001, HIPAA under a BAA on Enterprise plans, and GDPR/UK GDPR via EU data residency; SOC 2 Type II attestation is in progress for Q3 2026.
Audit and support: Every query, mutation and policy evaluation is captured in a tamper-evident log; enterprise plans can integrate Splunk, Datadog and Elastic, and vulnerability reports receive a response within one business day.
Standards: Fluree is built on W3C standards including JSON-LD, RDF, SPARQL, OWL and SHACL.
Headquarters: Winston-Salem, North Carolina, USA
