What it is
Weaviate is an open-source vector database for storing, indexing, and searching high-dimensional vectors, intended as infrastructure for search, retrieval-augmented generation (RAG), and agents. Its hybrid search combines vector retrieval with BM25 keyword search, and it also supports semantic and keyword search. Other listed capabilities include advanced filtering, vectorizer modules, configurable backups, native multi-tenancy, vector-index compression, and tenant isolation. Weaviate can run as a hosted service or as a self-managed instance locally or with a cloud provider; Docker and Kubernetes are deployment options. Integrations include AWS, Google Cloud, Azure, OpenAI, Anthropic, Cohere, Hugging Face, and Ollama. Weaviate Cloud encrypts data in transit and at rest, supports role-based access controls, and provides automated daily backups. The Free plan includes up to 100,000 objects, one collection, and three tenants, but has no backups or high-availability replication. Flex starts at $45 a month, and Premium costs $400 a month.
