Weaviate (alt)
Multimodal vector database โ GraphQL, REST, hybrid search
๐ Overview
Weaviate is an open-source multimodal vector database that supports text, image, and audio vectors with GraphQL and REST APIs. Unlike Qdrant (which focuses on performance), Weaviate emphasizes developer experience โ providing a GraphQL interface, automatic vectorization modules, and built-in multi-tenancy.
โจ Key Features
- โข15K+ GitHub stars โ multimodal vector database
- โขGraphQL and REST APIs
- โขAutomatic vectorization
- โขHybrid search
- โขMulti-tenancy
- โขBSD-3 licensed
๐ฏ The Problem It Solves
Building multimodal search applications requires combining vector search with structured filtering and automatic embedding generation. Weaviate provides all three in a single database.
๐ง How It Works
Weaviate stores objects with their vectors and supports hybrid search combining BM25 keyword matching with vector similarity. Automatic vectorization modules call OpenAI/Cohere/HuggingFace to generate embeddings on ingest.

๐ฌ Practitioner Verdict
โWeaviate is the best vector database for developer experience โ the GraphQL API and automatic vectorization are genuinely differentiated. The trade-off: slower than Qdrant for large-scale search, more resource-hungry, and the GraphQL API has a learning curve.โ
