An open-source OLTP graph-vector database built in Rust.
After more than a year of development, HelixDB is now generally available! Whether you're an indie hacker building custom agent memory, or a Fortune 500 that needs an infinitely scalable and highly available OLTP graph/vector database, we can handle your workload. Star the repo! https://github.com/HelixDB/helix-db
HelixDB is purpose-built for AI agent workflows with native vector and graph support. The managed Helix Cloud offering handles scaling and availability automatically, allowing developers to focus on agent logic rather than database operations.
HelixDB combines native vector and graph capabilities in a single database, enabling efficient semantic search and RAG workflows without managing separate systems. Built in Rust for performance, it scales to handle large volumes of embeddings and relationships needed for AI agent applications.
Helix Cloud provides auto-scaling reader nodes that scale up under load and down when demand drops, with object storage backing for cost efficiency. High availability is supported through multi-gateway and multi-node configurations, and users pay only for resources consumed.
HelixDB is a native graph database that handles complex relationship queries efficiently. Its graph-vector hybrid architecture allows users to combine structural relationships with semantic similarity, enabling rich knowledge representation and traversal.
