Lantern Database

The most powerful vector database for building AI applications. Open-source PostgreSQL database extension for vector data and vector search operations.

PostgreSQL built for AI applications

Unlike standalone vector engines, Lantern enables seamless combination of relational data and vector data for applications. Tap into the power of embedding models and large language models to easily build data-driven applications.

The best performance and 100% open-source

Lantern benchmarks outperform pgvector, the only other PostgreSQL extension on the market. Our commitment to open-source means Lantern is free for all. Benefit from the ever-growing enhancements and features that developers passionately contribute to.

Scale your applications without compromises

Extensions like pgvector utilize IVFflat, an algorithm that leads to clunky index management requirements and poor performance at scale. We built a vector database using a better algorithm, HNSW, to enable better throughput, latency, recall, and scalability.
