## What LanceDB does

- LanceDB supports vector similarity search, full-text search and SQL over stored data.
- LanceDB stores, queries and filters vectors, metadata and multimodal data such as text, images, videos and point clouds.
- LanceDB versions data automatically, so you can manage data versions without extra infrastructure.
- LanceDB can use GPUs to build vector indexes.
- LanceDB feeds training jobs by sampling, shuffling and scanning columns into GPU-ready batches from local or object storage.
- LanceDB offers reranking, embeddings, namespaces and feature engineering through Geneva, according to its documentation.
- LanceDB integrates with LangChain, LlamaIndex, Apache Arrow, Pandas, Polars and DuckDB.

### How it works

LanceDB OSS is an embedded library that runs locally or in your cloud. You call it from Python, TypeScript or Rust SDKs, or through a REST API. Data is stored in the Lance columnar format on local storage or object storage. LanceDB Enterprise adds production-scale search without servers to manage.

## How to install LanceDB

**From npm**

```
npm install @lancedb/lancedb
```

### Requirements

- Python 3.10 or later for the lancedb Python package.
- Node.js 22 or later for the @lancedb/lancedb npm package.

### First steps

1. Follow the LanceDB Quickstart guide at docs.lancedb.com to set up LanceDB locally.
2. Choose the LanceDB Python, TypeScript or Rust SDK, or use the REST API.

## Who LanceDB is for

- Developers building semantic, image or multimodal search into AI applications.
- ML teams that need one versioned table for curation, features, retrieval and training data.
- Python and JavaScript developers who want an embedded vector database without running a server.

### Limitations

- LanceDB OSS targets local and regular-scale workflows. The docs position LanceDB Enterprise for larger-scale needs.
- Recent LanceDB pre-releases include breaking changes, such as lazy iterators for table listings and renamed MemWAL APIs.
