From my experience with Qdrant, I found it excels at delivering high-performance vector search capabilities that scale well for real-time AI applications. Its open-source nature and support for real-time updates make it a flexible choice for developers building semantic search or recommendation systems. However, the open-source version requires self-hosting, which may add operational overhead for some teams. Overall, if you need a robust vector search engine with filtering and multi-language SDK support, Qdrant offers a solid, production-ready solution.
