## What it is
HelixDB is an open-source OLTP graph-vector database written in Rust that combines labeled property graphs with native vector, full-text, and temporal search on object storage. It ships with a CLI, SDKs for TypeScript, Python, Go, and Rust, an embedded runtime, and a cloud offering, targeting AI memory, GraphRAG, and company-knowledge applications.

## Use cases
- store long-term memory for AI agents
- build a GraphRAG assistant with graph traversal and vector search
- create a company brain searching people, projects, and documents together
- map code dependencies and search a codebase semantically
- build recommendations combining relationships and similarity
- run a self-hosted graph-vector database on object storage
- query knowledge graphs with vector and full-text search in one engine

## When to choose
- you need graph relationships, vector similarity, and full-text search in a single transactional store
- you are building AI agent memory, GraphRAG, or enterprise knowledge applications
- you want an embedded or self-hosted database backed by object storage with low cost at scale
- you want pre-filtering so vector results respect graph and permission boundaries

## When to avoid
- you need a mature, battle-tested database with a long production track record
- you only need a simple key-value or relational store without graph or vector features
- you require a large ecosystem of third-party tools and connectors
- you need heavy analytical (OLAP) workloads rather than OLTP
