What is the difference between Qdrant and Qdrant Cloud?

Qdrant the open-source project is the core database you can self-host on any infrastructure for free, with all features except commercial support included. Qdrant Cloud is the managed SaaS offering run by Qdrant Solutions that handles deployment, scaling, backups, monitoring, and upgrades on AWS, GCP, or Azure, with pricing based on cluster size. Qdrant Hybrid Cloud lets you run compute in your own cloud account with the control plane managed by Qdrant, giving data-residency compliance with managed operations. All three use the same binary and API.
