What Is Weaviate
Weaviate is an open-source vector database. It stores embeddings for semantic search and supports hybrid search that blends vector similarity with traditional keyword matching.
In Practice
Weaviate appeals to teams that want control — self-hosting for data privacy and cost, or its managed cloud for convenience. Its hybrid search makes it strong for RAG systems where both meaning and exact terms matter.
