Weaviate is an open-source AI database for building vector search, retrieval-augmented generation (RAG) and agentic AI applications on one platform. It can be used as a fully managed cloud service or self-managed on your own infrastructure.
The vector database stores, indexes and searches high-dimensional vectors at large scale and forms the base for search, RAG and agent features. Weaviate reports more than 20 million open-source downloads and thousands of customers.
Key features include a Query Agent that turns natural-language questions into optimised database queries, built-in embedding generation from text, images and other data without an external pipeline, multi-tenancy for large numbers of segmented indexes, replication, and role-based access control.
Managed clusters run on AWS, Google Cloud and Azure, with uptime targets of 99.5 percent on the Flex plan and up to 99.95 percent on Premium. Weaviate also lists platform partnerships with AWS, Google Cloud, Snowflake and Databricks.
Customer stories on the site cover RAG for customer support, multi-tenant search, research workflows in banking and secure document processing, with deployments holding billions of vectors in production.
Pricing: the Free plan is always free with no credit card and includes one cluster, 100,000 objects, 1 GB memory, 10 GB disk, one collection with up to three tenants, 2,000 embedding requests per day and 1,000 Query Agent requests per month. The Flex plan starts at 45 USD per month on a pay-as-you-go basis with no commitment. Premium uses a prepaid contract with shared or dedicated deployment and enterprise support through sales. Self-managed pricing is also available, and a pricing calculator estimates costs.
Weaviate is suited to developers, startups and enterprises building semantic search, RAG chatbots, recommendation systems and AI agents that need a scalable vector database.
