An open-source embedded retrieval library for multimodal AI, offering fast vector search, SQL, and full-text search.
LanceDB is an open-source embedded retrieval library for multimodal AI, designed as a multimodal AI lakehouse. It provides fast, scalable vector search capabilities, allowing developers to store, index, and query petabytes of multimodal data and vectors. It solves the problem of managing and retrieving large-scale AI data efficiently.
AI/ML developers, data engineers, and researchers building production-ready AI applications that require efficient storage and retrieval of multimodal data and vectors.
Developers choose LanceDB for its fast vector search, multimodal support, seamless integration with popular AI frameworks, and the ability to run locally or in the cloud without vendor lock-in.
Developer-friendly OSS embedded retrieval library for multimodal AI. Search More; Manage Less.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Search billions of vectors in milliseconds with state-of-the-art indexing, as highlighted in the key features, enabling high-performance AI retrieval.
Store, query, and filter vectors, metadata, and multimodal data like text, images, videos, and point clouds, providing versatility for diverse AI workloads.
Supports vector similarity search, full-text search, and SQL queries, offering flexible data retrieval options beyond just vector operations.
Integrates with LangChain, LlamaIndex, Apache Arrow, Pandas, and Polars via Python, Node.js, Rust, and REST APIs, easing adoption in existing pipelines.
The multimodal lakehouse architecture and columnar storage require understanding of AI data workflows, which can be complex for teams new to vector databases.
While open-source, running LanceDB locally involves managing storage and infrastructure, unlike fully managed services that handle scaling and maintenance automatically.
As a newer project, some integrations and advanced features might be less polished or documented compared to established alternatives like Pinecone or Weaviate.
