The full breakdown - performance, comparisons, and setup
Weaviate
Weaviate stands out from other vector databases because it handles the entire embedding pipeline internally. You send it raw text, it vectorizes it using a module of your choice, indexes it, and makes it searchable - all within the same system.
What it is
Weaviate is a vector search engine and database that comes with built-in vectorization modules. Instead of running a separate embedding service and managing two infrastructure components, you configure Weaviate to use Ollama, OpenAI, Cohere, or HuggingFace models, and it handles vectorization automatically.
