HelixDB
The Infinitely Scalable Graph Database

HelixDB is a native graph-vector database built in Rust, designed for use cases like RAG, semantic search, knowledge graphs, and AI agent workflows. It targets developers building AI-driven applications that require combined graph and vector storage. The project has an open-source community presence on GitHub and Discord.
HelixDB combines graph and vector storage in a single Rust-built database engine, enabling queries across relational graph structures and high-dimensional vector spaces simultaneously.
