Pinecone
Managed vector database for AI applications
Pinecone is the leading managed vector database service for AI applications. It stores and searches high-dimensional vector embeddings at scale, making it the backbone of RAG (Retrieval Augmented Generation) systems, semantic search, and recommendation engines. Pinecone is serverless and scales to billions of vectors.
Weaviate
Open-source AI-native vector database
Weaviate is an open-source, AI-native vector database that stores objects and their vector representations. It enables hybrid search combining vector similarity with traditional keyword search, making it ideal for complex RAG and AI application architectures. Weaviate supports automatic vectorization through module integrations.
