About Weaviate

An open-source vector database built for storing and querying AI-generated embeddings.

Weaviate is a vector database that lets developers store objects alongside their vector embeddings and perform similarity searches at scale. It is designed for applications that work with machine learning models, such as semantic search, recommendation systems, and retrieval-augmented generation (RAG) pipelines. Developers can run it self-hosted or use a managed cloud version.

Where to start

Start with the general Weaviate documentation to set up an instance, then use the official JS/TS client to connect your application and interact with collections and queries.
