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.
