Open-source AI-native vector database with built-in hybrid search and multi-tenancy, usable self-hosted or via managed Weaviate Cloud.
Last verified:
Weaviate is an open-source (BSD-3-Clause), AI-native database that stores objects, vectors, and inverted indexes together, positioning itself as a primary database for AI-native apps rather than just a secondary vector store, with built-in hybrid search, multi-tenancy, and optional built-in embeddings. It can be self-hosted via Docker or Kubernetes for free, or run on managed Weaviate Cloud with Flex (pay-as-you-go) and Premium (contracted, dedicated) tiers spanning AWS, GCP, and Azure. Founded in 2019 (originally as SeMI Technologies) and headquartered in Amsterdam, Netherlands, Weaviate has raised roughly $67.6M total, including a $50M Series B in April 2023 led by Index Ventures.
