Activating a product opens its read here. Activating the selected product opens its hub.
Each product sits on the layers it owns, placed left to right by how far its positive sources lead its negative ones. A disc's area is its sources in this view and its tone is its band. Products with fewer than 20 sources from 15 authors have no net and sit at the right, under Unscored. The teal line joins Qdrant across its layers.

Stack Footprint
What is Qdrant used for, and by whom?
Vector Databases, also listed under retrieval & embeddings and AI engineering.
Model
Model APIs: Touches
Model APIs, touches. Qdrant Cloud Inference hosts a range of embedding models, some for free, and can call embedding models from OpenAI, Cohere, Jina AI and OpenRouter with your own API key. Generation models stay with a model API.
Model gateway: Touches
Model gateway, touches. OpenRouter is one of the external embedding providers Cloud Inference can call with your own key. Routing generation traffic stays with a gateway.
Build
Orchestration: Touches
Orchestration, touches. LangChain ships the langchain-qdrant partner package with dense, sparse and hybrid retrieval, the Qdrant team maintains the Haystack document store, and LlamaIndex is on Qdrant's framework list. The agent logic stays in the framework.
Tool use: Touches
Tool use, touches. Qdrant exposes a REST API with an OpenAPI 3.0 specification and a gRPC interface, with clients for Python, TypeScript, Rust, Go, Java and .NET, which an agent's retrieval tool calls.
Data
Retrieval: Core
Retrieval, core. This is Qdrant's primary role: it stores dense, sparse and multivector embeddings, filters on JSON payloads, merges hybrid results with Reciprocal Rank Fusion or Distribution-Based Score Fusion, and cuts RAM with built-in quantization.
Evaluate
Evaluation: Touches
Evaluation, touches. Qdrant serves the retrieval results an evaluation measures. Scoring answers stays with an evaluation product.
Operate
Observability: Touches
Observability, touches. From Qdrant v1.17.0, audit logs record API operations on paid Cloud clusters and in self-hosted Qdrant. Tracing an application's requests stays with an observability tool.
Cloud deployment: Supports
Cloud deployment, supports. Qdrant Managed Cloud runs on AWS, GCP and Azure with data stored in the cluster's region, and Hybrid Cloud runs in your own infrastructure. The cloud account and the rest of the application stay with your cloud provider.
Guardrails: Touches
Guardrails, touches. Qdrant holds SOC 2 Type 2 and HIPAA certifications and offers single sign-on on Premium, which secure the data store. Prompt and output guardrails stay with a security product.

How to read this map. Each layer lists the products that structurally own it, so a product that only touches a layer isn't listed among its owners. Qdrant is underlined in teal where it is Core, and its rows sit a shade lighter; where it supports or touches a layer, that row names it first.
