Documentation

Qdrant (read: quadrant) is a vector similarity search engine. Use our documentation to develop a production-ready service with a convenient API to store, search, and manage vectors with an additional payload. Qdrant’s expanding features allow for all sorts of neural network or semantic-based matching, faceted search, and other applications.

First-Time Users:

There are three ways to use Qdrant:

  1. Run a Docker image if you don’t have a Python development environment. Setup a local Qdrant server and storage in a few moments.
  2. Get the Python client if you’re familiar with Python. Just pip install qdrant-client. The client also supports an in-memory database.
  3. Spin up a Qdrant Cloud cluster: the recommended method to run Qdrant in production. Read Quickstart to setup your first instance.

Local mode workflow

First, try Qdrant locally using the Qdrant Client and with the help of our Tutorials and Guides. Develop a sample app from our Examples list and try it using a Qdrant Docker container. Then, when you are ready for production, deploy to a Free Tier Qdrant Cloud cluster.

Try Qdrant with Practice Data:

You may always use our Practice Datasets to build with Qdrant. This page will be regularly updated with dataset snapshots you can use to bootstrap complete projects.
