Products that do what HelixDB – Native graph and vector types for RAG and retrieval does

Hey HN! We're college friends building HelixDB. It's a database that natively supports both graph and vector types. It’s designed for AI-driven apps like RAG, vector search, code indexing, and agent frameworks where you need both explicit relationships and similarity. We came up with the idea for Helix at university, while building a graph database as a side project in Rust. Reading some research papers on RAG setups, I realised there was a lot of infrastructure setup to get started. You need your own server, a graph database, a vector database and then some bespoke middleman software to…
