# Weaviate

Weaviate is an open-source, AI-native vector database that stores objects and vectors together and supports vector search, keyword search, hybrid search, filtering, multi-tenancy, and retrieval-augmented generation.

Use Weaviate as the retrieval and data layer for AI applications. Start with Weaviate Cloud for a managed deployment, or run the open-source database yourself when you need infrastructure control or on-premises deployment.

- You are building RAG, search, recommendation, personalization, or agent-memory applications.
- Filtering, multi-tenancy, replication, and production scaling are important.
- You want a managed cloud service with a path to self-hosting.

Pair Weaviate with a relational database for transactional joins, an analytical database for large-scale OLAP workloads, or a graph database for graph traversal.
