LanceDB is a serverless vector database that runs embedded in your application. No server process, no Docker — just pip install and go. Built on the Lance columnar format for maximum performance. Why LanceDB is the Simplest Vector DB A data scientist needed to prototype a RAG app but didn't want to run Docker or manage infrastructure. LanceDB runs entirely in-process — pip install, import, done. Key Features: Serverless — No separate process, runs embedded Lance Format — Columnar storage optimized for ML workloads Multi-Modal — Store text, images, video, point clouds Full-Text Search — Combined with vector search Zero-Copy — Memory-mapped for fast access Quick Start pip install lancedb import lancedb db = lancedb . connect ( " ~/.lancedb " ) table = db . create_table ( " articles " , data = [ { " text " : " Python is great " , " vector " : [ 0.1 , 0.2 , 0.3 ]}, { " text " : " Rust is fast " , " vector " : [ 0.4 , 0.5 , 0.6 ]} ]) results = table . search ([ 0.1 , 0.2 , 0.35 ]). limit (
