What is Weaviate?
Weaviate allows you to store and search data objects based on their meaning, not just keywords, making search incredibly smart.
About
Weaviate is an open-source vector database for building AI search, retrieval-augmented generation and agent applications. It stores objects alongside their vector embeddings and supports vector, keyword and hybrid search, filtering and multi-tenancy, with built-in embedding services and a Query Agent that answers natural-language questions over your data. Developers can self-host the open-source version or use Weaviate's managed cloud. The cloud has an always-free tier with one small cluster and no credit card. The Flex plan is pay-as-you-go with no commitment and starts at $45 per month, while Premium plans with shared or dedicated clusters and higher uptime are sold on prepaid contracts through sales.
