HelixDB is an open-source OLTP graph-vector database built in Rust that combines graph database capabilities with vector database functionality. The database is designed to handle online transaction processing workloads while providing graph and vector data management capabilities.

The database offers infinitely scalable and highly available OLTP graph-vector database functionality. It can handle workloads ranging from custom agent memory for indie hackers to enterprise-scale requirements for Fortune 500 companies. The system has executed billions of queries and has demonstrated performance that outperforms industry-leading competitors.

HelixDB is built using Rust programming language and has been developed over more than a year before reaching general availability. The database has grown to nearly 4,000 stars on GitHub, indicating significant developer interest and adoption.

The product benefits both individual developers working on AI applications requiring custom agent memory and large enterprises needing scalable database solutions. It serves use cases involving graph data relationships combined with vector similarity search capabilities.

The target users include indie hackers building AI applications and Fortune 500 companies requiring enterprise-grade database solutions. The database has attracted attention from developers at major companies and has been developed with support from Y Combinator.
