Overview

HelixDB is an open-source graph-vector database built in Rust, designed for AI agents and RAG systems. It unifies vector similarity search and graph traversal within a single, type-safe engine, eliminating the need for multiple databases and reducing operational costs by up to 50%. The platform offers high performance with vector searches averaging 2ms and graph traversals under 1ms. Targeted at developers, it provides tools like CLI and SDKs for easy deployment either locally or via a managed cloud service with enterprise-grade security. Backed by Y Combinator and NVIDIA, it serves as the infrastructure for contextual data reasoning in modern AI applications.
