The Embedded Vector Database
LanceDB is an open source embedded vector database. Run it inside your application or notebook. No clusters, no containers, no separate service. Install the library, point it at a local path, start building.

Why teams switch
Open source, vendor-flexible
Apache 2.0 license. Audit the code. Run on your hardware. Built on the open Lance format with Arrow types.
Embedded simplicity
Runs in-process. No Docker, no K8s, no separate service. Native Python and TypeScript clients.
Same code, local to cloud
The embedded library and managed service share the same format and query engine. Swap endpoints, not code.
Full-text + hybrid search, native
Vector, full-text, and SQL queries in one system. Built for S3, not bolted on.
Comparison
The Power of the Lance Format
Vector Search
- Fast scans and random access from the same table — no tradeoff
- Zero-copy access for high throughput without serialization overhead
Multi-Modal
- Raw data, embeddings, and metadata in one table — not pointers to blob storage
- No separate metadata store to keep in sync
Enterprise-Grade Requirements
Security
Granular RBAC, SSO integration, and VPC deployment options.
Governance
Data versioning and time-travel capabilities for auditability.
Support
Dedicated technical account management and guaranteed SLAs.
