HelixDB is an open-source OLTP graph-vector database built in Rust that combines the power of graph and vector types natively. It is designed to build RAG and AI applications easily while providing infinite scalability and high availability for various workloads.

HelixDB features extremely efficient graph structures for high throughput and low latency. Graph and vector queries are compiled for optimal performance. The database offers Helix Lite for prototyping and low-latency applications, with options to run locally or on Helix Cloud.

The database uses native graph-vector integration built in Rust, combining graph and vector capabilities at the core level. This approach enables efficient query compilation and optimized data structures for performance.

HelixDB benefits developers building custom agent memory systems and enterprises needing scalable OLTP graph/vector databases. It supports RAG applications and AI workloads with its combined graph-vector architecture.

The target users include indie hackers building custom agent memory and Fortune 500 companies requiring scalable database solutions. It integrates with applications through standard database interfaces and offers both cloud and local deployment options.
