FAISS alternative. Production vector search without building your own infrastructure.
Using FAISS? LanceDB gives you the same fast algorithms with built-in persistence, indexing, full-text search, and query capabilities (no custom wrapper required).

Why teams switch
Compute-storage separation
Complete database on object storage. No DIY persistence layer. Up to 100x savings at scale.
One table, not six systems
Raw data, embeddings, and features together. No custom serialization, no external metadata store.
Schema evolution without rebuilds
New embedding model? Add a column. No index rebuild, no custom migration code.
Full-text + hybrid search, native
Vector, full-text, and SQL queries in one system. FAISS is vector-only.
Comparison
FAISS
LanceDB
Cost
Library - you build the persistence and scaling layer.
Complete database with object storage. Up to 100x savings at scale.
Scale
You manage infrastructure and scaling.
20 PB largest table. 20K+ QPS. Billions of vectors.
Search
Vector similarity only.
Native vector, full-text, and SQL hybrid search in one query.
Data model
Index library — no built-in data management.
Schema evolution - raw data, embeddings, and features in one table.
Production
Build your own query, persistence, and serving layer.
Embedded to cloud-scale with built-in serving.
Best for
Research, benchmarks, custom infra teams.
Production vector search without DIY infrastructure.
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.
