Weaviate is an open‑source, deployment‑agnostic AI database that lets developers design, build and ship AI‑native applications. It stores, indexes and searches high‑dimensional vectors at any scale, providing the foundation for vector search, retrieval‑augmented generation (RAG) and autonomous agents. The platform includes built‑in vector generation from text, images and other data types, so you don’t need an external embedding pipeline, and a Query Agent that translates natural‑language questions into optimized database queries. Weaviate offers SDKs for Python, Go, TypeScript and JavaScript, plus GraphQL and REST APIs, and can run in the cloud or on‑premises with auto‑scaling, tenant isolation and enterprise‑grade security. Pricing includes a free tier (one cluster per user, 100,000 objects, 1 GB memory, 10 GB disk, limited embeddings and Query Agent requests) and paid plans with pay‑as‑you‑go or prepaid contracts, higher uptime guarantees and dedicated support.
