SimpleVecDB – Local vector database powered by sqlite-vec

Summary: SimpleVecDB is a zero-infrastructure vector search solution that stores vectors in a single portable SQLite file. It offers ~2ms query latency, 32x storage compression, hybrid BM25 and vector search, and integrates with LangChain and LlamaIndex without requiring servers or cloud services.

What it does

SimpleVecDB enables local vector search by embedding vectors in a single SQLite database using sqlite-vec technology. It supports hybrid BM25 and vector queries with fast performance and reduced storage size.

Who it's for

It targets indie hackers, teams prototyping local retrieval-augmented generation (RAG) apps, and privacy-focused projects avoiding external APIs.

Why it matters

It eliminates the need for infrastructure, containers, or cloud accounts for vector search in local AI applications, keeping data fully local and portable.
