Qdrant
FreemiumHigh-performance open-source vector database.
Open-source vector database with filtering and hybrid search.
Why Qdrant matters
Qdrant is a go-to when you want strong filtering, Rust performance, and the option to self-host or use cloud. It is often the open alternative to fully managed vector DBs for RAG and recommendation systems.
