What is the difference between Pinecone and Qdrant?

Pinecone is a fully managed proprietary vector database with serverless and pod-based deployment, focused on zero-ops simplicity and tight AWS, GCP, and Azure integration. Qdrant is an open-source vector database written in Rust that offers a managed cloud option and self-hosting, with strong filtering, payload support, and quantization features. Pinecone wins on ease of use and enterprise support, while Qdrant wins on cost at scale, self-hosting flexibility, and fine-grained control over index internals and metadata filtering.
