## Where Qdrant stands out

- **SQL / existing-DB integration** — 3 of 6 apps with a verified answer have this

## Overview

- **Who it's for**: Qdrant is aimed at developers and teams building AI applications that need vector similarity search, such as retrieval-augmented generation (RAG), semantic search, and recommendation systems. It suits both small self-hosted projects (via Docker or Kubernetes) and enterprises that need dedicated, compliant infrastructure through Qdrant Cloud, Hybrid Cloud, or Private Cloud.
- **What you get**: Qdrant is an open-source (Apache License 2.0) vector search engine written in Rust that stores points (vectors plus a JSON payload) in collections and lets you query them by similarity, with support for dense, sparse, and multivector search, payload filtering, and hybrid fusion methods like Reciprocal Rank Fusion. It can be run for free as a self-hosted Docker container or Kubernetes deployment, or consumed as Qdrant Cloud, which offers a free tier and paid Managed/Hybrid/Private tiers with usage-based, resource-metered billing starting from $25.
- **How it works**: Clients connect to a Qdrant instance over REST or gRPC using official SDKs (Python, JavaScript/TypeScript, Go, Rust, Java, .NET), create collections with a chosen distance metric, and upsert points whose vectors become searchable immediately via a write-ahead log. Qdrant scales horizontally through sharding and replication across cluster nodes, supports payload-based multitenancy within a single collection, and can generate embeddings inline through its FastEmbed integration or Cloud Inference rather than requiring a separate embedding pipeline.
