About Lancedb
LanceDB is an open source, embedded retrieval library for multimodal AI applications. It is built on the Lance columnar format and is intended for storing, indexing and searching vectors and multimodal data, such as text, images and videos. The project is hosted on GitHub and is licensed under Apache-2.0. Developers can use Python, Node.js, Rust and REST APIs to integrate it.
The homepage describes a cloud and enterprise offering in addition to the open source library, but it does not state pricing. The source lists the pricing status as unknown. The homepage also describes data sovereignty and security for the cloud offering. This entry does not verify those claims.
