**APIs profiled:** 22

Weaviate is an open-source, AI-native vector database that enables developers to build semantic search and AI-powered applications. It stores data as vector embeddings alongside structured properties, enabling lightning-fast similarity search using HNSW or flat indexes. Weaviate supports multi-tenancy, automatic vectorization via configurable modules, GraphQL and REST APIs, and enterprise features including authentication, authorization, backups, and replication.
