What this product helps you do

Weaviate combines an open-source vector database with a managed cloud service. Developers can index objects and embeddings, run vector, keyword, or hybrid search, connect external model providers, and use retrieved data in RAG and agent applications. Weaviate Cloud has a free managed tier plus usage-based and contracted plans; self-hosting shifts infrastructure and operations to the adopter.

Problems it solves

  • Semantic and similarity search require specialized vector indexing
  • Applications need keyword and vector retrieval over the same stored objects
  • RAG systems need a searchable data layer for grounding model responses
  • Teams must choose between operating a database themselves and using a managed service

Weaviate is an open-source vector database that stores data objects alongside vector embeddings. It supports semantic, keyword, and hybrid search and can provide retrieved context to generative AI and agent applications.

Teams can operate the database themselves or use Weaviate Cloud. Current cloud options include an always-free managed tier, pay-as-you-go Flex clusters, and contracted Premium deployments, with separate usage dimensions and optional AI services.
