HelixDB

HelixDB

HelixDB is a graph-vector database written in Rust that holds relational records, graph edges and embeddings in one store, aimed at knowledge graphs and agent memory. Queries are written in its own query language and compiled, and it persists to object storage. SDKs for several languages ship in the repository.

Apache-2.0 license body confirmed. The repository is public and unarchived and builds the whole product, and the README describes no paid tier, enterprise edition or license-gated build beside it, so source is public and the core ungated.

Adoption

2 low confidence
2.0

5,798 GitHub stars, which lands in the 1K-10K stars band of the stars scale, level 2. Distributed as a Rust binary and a CLI with no package-registry channel of its own, so the stars scale is the only instrument available; its cap of 3 applies and this band sits below it.

Capability

3 medium confidence
3.0

Banded on the category feature matrix as single-purpose store or index. Placed two bands below the vespa anchor, on a matrix that bands on how much of the persist-index-retrieve path a product provides itself, at what scale and over how many retrieval modes.

    README still documents a graph-vector database for knowledge graphs and AI memory, built in Rust, presenting the components an AI application needs in one platform rather than a separate application, relational and vector database.
