kind: opensource
description: LanceDB is the AI-Native multimodal lakehouse built on the open-source Lance columnar storage format. It pairs
  an Apache 2.0 licensed embedded retrieval library (Python, TypeScript, Rust, Go, C, Java SDKs) with a managed cloud service
  (LanceDB Cloud) and an enterprise lakehouse (LanceDB Enterprise) that unify vector, full-text, hybrid, and SQL search across
  billions of multimodal records. The REST surface is governed by the open Lance Namespace specification (OpenAPI 3.1) covering
  namespace, table, index, tag, and transaction operations with first-class support for materialized views, schema evolution,
  and time-travel versioning. LanceDB is used in production by Midjourney, Runway, World Labs, Netflix, Character.AI, Uber,
  NVIDIA, ByteDance, Databricks, and others for RAG, agent memory, training data curation, feature engineering, and large-scale
  retrieval.
