What is Weaviate?
Weaviate is an open-source vector database from Amsterdam that stores objects together with their vectors. Teams use it for semantic and hybrid search, retrieval-augmented generation and agent workflows, self-hosted or in Weaviate Cloud.
Weaviate combines a vector index with object storage, multi-tenancy, role-based access and replication. Weaviate Cloud runs on Google Cloud, AWS and Azure, with a free tier, the pay-as-you-go Flex plan and Premium plans for dedicated deployments and more regions. Hosted embedding models and the Query Agent are billed separately. Weaviate B.V. is based in Amsterdam; its security page lists SOC 2 and HIPAA and links to a trust portal.
