Lantern – a PostgreSQL vector database for building AI applications
We are excited to share Lantern! Lantern is a PostgreSQL vector database extension for building AI applications. Install and use our extension here: https://github.com/lanterndata/lantern We have the most complete feature set of all the PostgreSQL vector database extensions. Our database is built on top of usearch — a state of the art implementation of HNSW, the most scalable and performant algorithm for handling vector search. There’s three key metrics we track. CREATE INDEX time, SELECT throughput, and SELECT latency. We match or outperform pgvector and pg_embedding…
Lantern – a PostgreSQL vector database for building AI applications launched on September 13, 2023 with 196 votes, #223 of 4,228 launches that month and more than 95% of that year's launches. The site was not reachable when checked in September 2026.
In plain words
Lantern is a PostgreSQL vector database extension that enables developers to build AI applications directly within their database. It uses HNSW algorithm technology for vector search and offers a complete feature set for embedding generation and semantic search capabilities. The extension is designed to match or exceed the performance of competing PostgreSQL vector solutions across index creation time, query throughput, and query latency metrics.

HelixDB – Open-source vector-graph database for AI applications (Rust)2025 · github.com · ▲237Hey HN, we want to share HelixDB (https://github.com/HelixDB/helix-db/), a project a college friend and I are working on. It’s a new database that natively intertwines graph and vector types, without sacrificing performance. It’s written in Rust and our initial focus is on supporting RAG. Here’s a video runthrough: https://screen.studio/share/szgQu3yq. Why a hybrid? Vector databases are useful for similarity queries, while graph databases are useful for relationship queries. Each stores data in a way that’s best for its main type of query (e.g.…
