HelixDB

An open-source database that stores graphs, vectors and text search together.

New this week

What it does

HelixDB is a database that combines three things in one engine: a graph of connected entities, vector search that finds items by meaning, and keyword text search.

This mix is useful for AI apps that need to store entities, relationships, embeddings and text and query them together.

You can query it from Rust, TypeScript, Go or Python, and run a local instance for development.

Who it's for

Developers building AI apps that need connected data and meaning-based search in one place.

Can I use it without coding?

Developers only. It is a database used by developers, with a command-line tool to run it. New to this? Start here.
