Qdrant is a vector database and vector similarity search engine written in Rust. Developers use it to store and search vectors with attached data, for example for semantic search and AI applications built on embeddings. Qdrant is released under the Apache 2.0 licence and can be self-hosted, for instance with Docker. The company also offers Qdrant Cloud as a managed service on AWS, GCP or Azure, a Hybrid Cloud on your own Kubernetes, a Private Cloud for isolated deployments and Qdrant Edge.
The company behind Qdrant is Qdrant Solutions GmbH, based in Berlin. The documentation does not list the hosting regions of the managed cloud; you choose the region when creating a cluster, and the managed service runs on US hyperscalers. Self-hosting on your own infrastructure or in a European cloud keeps the data entirely under your control. For a European organisation with strict jurisdiction requirements, self-hosting or the Hybrid Cloud is therefore the most verifiable route.
