Why Qdrant? (English)
English adaptation of xb/doc/WHY_QDRANT.md. It explains why Qdrant became the first officially supported vector backend.
Reasons to choose Qdrant

- Operational maturity – horizontal scaling, snapshots, cloud + self-hosted options.
- JSON-first design – easy to integrate with xb’s
Custom.Generate.
- Open-source friendly – permissive license and strong community.
