Qdrant
Qdrant is an open-source vector database written in Rust, optimized for high-performance similarity search with rich filtering, named vectors, and on-disk indexing. Free self-hosted; Qdrant Cloud from $0/month free tier. Fastest growing vector database in production deployments.
Qdrant is the best starting point for teams that want a self-hosted vector database they can actually run in production without a dedicated ops team. If managed-only is acceptable and you don't want to run infrastructure, Pinecone's serverless tier is simpler - Qdrant shines when you control the deployment.
