Qdrant
Qdrant is an open-source vector database built for AI applications. It stores and searches high-dimensional vectors with metadata filtering, enabling semantic search, recommendation engines, and retrieval-augmented generation (RAG). Qdrant supports dense and sparse vectors, hybrid search, quantization for memory efficiency, and distributed deployment. Available as a managed cloud service or self-hosted, it offers gRPC and REST APIs, handles billions of vectors, and integrates with embedding models and LLM frameworks for production AI workloads.
