Qdrant - Vector Search Engine

Categories: Coding & Developer Tools, Data Analysis, Productivity  |  Pricing: Freemium  |  Official Website ↗

Qdrant is a high-performance vector search engine and database designed for building AI retrieval systems at scale.

Qdrant is an open-source vector database engineered for real-time, high-performance vector search at any scale and with various deployment models. It enables AI builders to ship full-feature vector search, supporting expansive metadata filters, native hybrid search (dense + sparse), and built-in multivector capabilities. The platform is designed for production-grade AI search, offering efficient one-stage filtering and full-spectrum reranking. Qdrant provides flexible deployment options including Qdrant Cloud (fully managed), Qdrant Hybrid Cloud (bring your own Kubernetes), Qdrant Private Cloud (air-gapped deployments), and Qdrant Edge (lightweight, low-latency). It is built in Rust with SIMD and a custom storage engine for optimal performance, real-time indexing, and memory-efficient storage. The platform also offers developer-friendly APIs, a built-in Web UI, and native cloud inference for generating embeddings.
