The Multimodal Lakehouse for AI
How to Install ✦ Detailed Documentation ✦ Tutorials and Recipes ✦ Contributors
The ultimate multimodal data platform for AI/ML applications.
LanceDB is designed for fast, scalable, and production-ready vector search. It is built on top of the Lance columnar format. You can store, index, and search over petabytes of multimodal data and vectors with ease. LanceDB is a central location where developers can build, train and analyze their AI workloads.

Order: strongest tier first, then most downloads, then name, with unmeasured values last. A library counts downloads over 30 days. An app counts binary downloads per release. An app with none counts its crate downloads over 30 days. ML Rust runs this catalogue, so its closest project always gets a row.

Why FeaturedIt passes every Featured gate.
What it meets
- It has 63 active dependents and 60 new dependents in 365 days. Featured needs 11 active dependents or 9 new dependents in 365 days.
- Active dependents are at 99% of their peak. Featured needs at least 50%.
- Docs are present. The release commit or a manifest ties the crate to the repository.
- No vulnerability advisory stays unpatched past the grace window. At least one version is neither a prerelease nor 0.0.x.
- The last activity is on 8 Nov 2026, 1 day ago. The rules expect an update within 560 days. Dormancy rule
Exact rules: Featured library. The check on applied thresholds version 9.
