HelixDB is an open-source graph-vector database built in Rust, designed for high-performance intelligent data storage, particularly for RAG and AI applications. It targets developers seeking a reliable, fast, and user-friendly database solution for AI-driven workloads.

How It Works

HelixDB leverages Rust for performance and utilizes LMDB via the Heed wrapper for its storage engine. This combination provides fast startup times and millisecond query latency. Its vector-first design natively supports vector data types, making it suitable for AI and RAG, while its intuitive query language and built-in type checking enhance developer experience.

Quick Start & Requirements

• Install CLI: curl -sSL "https://install.helix-db.com" | bash
• Install Helix: helix install
• Setup: helix init --path <path-to-create-files-at>
• Check queries: helix check
• Deploy locally: helix deploy --local
• Additional commands: helix instances, helix stop <instance-id>, helix start <instance-id>
• Prerequisites: Rust, LMDB (managed by Heed).

Highlighted Details

• Built in Rust for performance and reliability.
• Native vector data type support for AI/RAG.
• Powered by LMDB via Heed for efficient storage.
• ACID compliant.
• Offers a managed cloud service.
