Qdrant
Open-source vector database for semantic search and AI applications
What it does well
- Exceptional query performance with sub-millisecond latencies at scale
- Rich filtering and hybrid search combining vectors with metadata/text search
- Flexible deployment: self-hosted, cloud, or fully managed options
- Strong production features including clustering, replication, and high availability
Where it falls short
- Smaller ecosystem and community compared to established vector databases
- Managed cloud pricing can be costly for very large-scale deployments
- Steeper learning curve for teams new to vector database concepts and operations
