Qdrant

Open-source vector search engine

Qdrant is an open-source vector search engine powering AI applications from semantic search and retrieval-augmented generation through to AI agents and real-time recommendations. Retrieval quality sets a hard ceiling on what any AI application can do, since a model reasoning over the wrong retrieved context fails regardless of its own capability — which is why the retrieval layer became infrastructure rather than a feature. Qdrant is trusted by global companies including Canva, HubSpot, Tripadvisor, Bosch and Deutsche Telekom, and operates as a remote-first international team.
