What is Qdrant?
Qdrant is a vector similarity search engine and vector database with an API for storing, searching, and managing vectors along with additional payloads (points). With extended filtering support, it can be used for neural network and semantic matching, faceted search, and more. It is written in Rust and is described as fast and reliable even under high load. You can install the open source version yourself, or deploy it as fully managed Qdrant Cloud (including a free tier), Hybrid Cloud, Private Cloud, or Edge (beta).
- Advanced filters on JSON metadata (nested, text, geo, etc.)
- Native hybrid search with dense + sparse vectors (BM25, SPLADE++, miniCOIL)
- Multivector support with several vectors per object
- First-stage filtering applied during HNSW traversal
- Score boosting, ColBERT, and MMR reranking
- Up to 64x memory savings with asymmetric, scalar, and binary quantization
- REST and gRPC APIs and official clients for Python, JavaScript, and more
- Built-in web UI and Qdrant Cloud embedding inference
Who uses Qdrant and for what
