LanceDB

LanceDB is an open-source, embedded vector database built on the Lance columnar format and intended for AI and multimodal data retrieval. It is developed by LanceDB and licensed under Apache-2.0, an open-source licence. The GitHub repository was created in 2023. It can be run embedded inside an application or self-managed. The latest release is v0.39.0, published on 17 September 2026, and the 0.x version number indicates the project has not reached a 1.0 release. Whether the company offers a managed cloud service or enterprise edition has not been verified, and pricing is not published in the material available, so buyers who need a hosted option or a commercial agreement should ask the vendor directly. The open-source software itself is free to use. LanceDB suits developers who want a vector store that runs inside their own application process without a separate server, particularly where data is held in columnar files. Teams that need a hosted service with published prices will need to confirm what is available before choosing it. The project shows as active, with a release in September 2026.
