HelixDB is an open-source graph-vector database built in Rust that combines graph and vector capabilities natively in a single platform for building RAG and AI applications.

What is HelixDB
HelixDB is a high-performance database system that brings together graph and vector data models in one unified platform. Built from scratch in Rust, it provides a comprehensive solution for AI applications by integrating semantic search capabilities with relationship modeling. The database was founded in 2025 by Xavier Cochran and George Curtis, and is available both as an open-source project and as a managed service for enterprise users. It features its own type-safe query language called HelixQL, which compiles into Rust code and runs as native endpoints.
Key Features of HelixDB
HelixDB is an open-source graph-vector database built in Rust that combines graph and vector data types in a single platform. It provides native support for both similarity searches and relationship queries, making it particularly suitable for RAG (Retrieval-Augmented Generation) and AI applications. The database offers high performance, type-safe queries through HelixQL, and built-in MCP support for AI agents to traverse and discover data within the graph. Hybrid Data Model:Natively combines graph and vector data types, supporting KV, documents, and relational data in a single platform HelixQL Query Language:Type-safe query language that compiles into Rust code and runs as native endpoints Built-in Vector Operations:Includes embedded functionality to vectorize text and perform vector operations without requiring separate embedding processes MCP Support:Built-in support for AI agents to discover and traverse data in the graph without generating human-readable queries
Use Cases
AI-Powered Search Systems: Enables semantic search combined with relationship-based queries for more contextual and accurate search results RAG Applications: Supports building retrieval-augmented generation systems by combining vector similarity search with structured relationship data AI Agent Systems: Provides infrastructure for AI agents to store, recall, and reason over contextual data in a single system
Pros
High performance with 2-3 orders of magnitude faster than Neo4j for vector search Simplified architecture by combining multiple database types in one platform Built with Rust for type safety and performance
Cons
Relatively new product with limited production usage Limited to 5MB database size by default (though configurable) Currently available only as a managed service for selected users
How to Use HelixDB
Install Prerequisites: Ensure you have Rust version 1.88.0 or higher installed. Run 'rustup update' to update Rust if needed. Add Dependencies: Add helix-db dependency to your Cargo.toml: [dependencies] helix-db = "0.1.0" Initialize Client: Create a new HelixDB client instance. Default port is 6969: let client = HelixDB::new(None); // Or specify custom port: let client = HelixDB::new(Some(8080)); Define Data Structures: Create Rust structs for your data using Serde for serialization/deserialization. Example: #[derive(Serialize)] struct UserInput { name: String, age: i32 } Write Queries: Use HelixQL to write type-safe queries that will be compiled to Rust code. Queries can combine vector search and graph traversals. Execute Queries: Use the client.query() method to execute queries: let result: UserOutput = client.query("addUser", &input).await?; Vector Operations: Use the built-in Embed function to vectorize text data. No pre-embedding required before sending to Helix. Graph Operations: Use MCP support to allow agents to discover data and walk the graph structure. Combine with vector search for hybrid queries. Access Control: Data is private by default and can only be accessed through compiled HelixQL queries.
HelixDB FAQs
1.What is HelixDB?
HelixDB is an open-source graph-vector database built in Rust that combines graph and vector data models in a single platform. It's designed to make building AI applications easier by eliminating the need for separate application DB, vector DB, graph DB, or multiple storage locations.
2.What types of data can HelixDB handle?
HelixDB primarily operates with graph + vector data model, but it can also support key-value (KV), documents, and relational data.
3.What are the key features of HelixDB?
HelixDB features lightweight design, lightning-fast startup times, millisecond query latency, built-in MCP support for agents, native embedding functionality, and private-by-default data access through compiled HelixQL queries.
4.How is HelixDB available to users?
HelixDB is available as a managed service for selected users, and offers enterprise support options. Interested users can contact them for more information and deployment options.
5.Does HelixDB support machine learning?
Yes, Helix ML uses the Deep Graph Library to offer machine learning capabilities directly on top of the graph, which helps improve prediction accuracy and reduces development time for implementing machine learning on graph data.
