What is Qdrant?
Qdrant is a high-performance open-source vector database written in Rust, optimized for speed and reliability. It supports advanced filtering with payload indexes, quantization for memory efficiency, and distributed deployments for horizontal scaling.
Qdrant offers both a self-hosted open-source version and a managed Qdrant Cloud service with free, hybrid cloud, and enterprise tiers. The Rust-based architecture provides memory safety without garbage collection overhead, leading to consistently low latency and high throughput.
Founded in 2021 and headquartered in Berlin, Germany, Qdrant has raised $37.8M in total funding including a $28M Series A led by Spark Capital in January 2024. The company is popular with teams that need production-grade vector search with fine-grained control over indexing and query parameters.
