- pricing
- freemium
- license
- Apache-2.0
Key features
- Expansive Metadata Filters — Store JSON metadata and apply nested, text, geo, and vector filters during search.
- Native Hybrid Search — Combine dense vector and sparse keyword queries (BM25, SPLADE++, miniCOIL) in a single request.
- Built-in Multivector Support — Attach multiple vectors per object for richer, multimodal retrieval.
- Real-Time Indexing — New vectors become searchable instantly without rebuilding the index.
- Memory-Efficient Storage — Store billions of vectors with optimized storage and up to 64× quantization compression.
- Developer-Friendly APIs — Access via REST, gRPC, and official Python/JavaScript clients with full control over HNSW and reranking.
- Enterprise Tooling — Includes RBAC, SSO, backups, point-in-time restore, and monitoring integrations (Prometheus, Grafana, Datadog).
- Multi-Cloud Deployment Options — Run on-prem, hybrid, edge, or fully managed Qdrant Cloud on AWS, Azure, or GCP.
Use cases
- Semantic search for large document corpora with real-time updates.
- Recommendation engines that match users to items via vector similarity.
- RAG pipelines that retrieve context-rich passages using hybrid dense-sparse search.
- AI agents requiring persistent memory and fast similarity lookup.
- Anomaly detection by finding outlier patterns in high-dimensional data.
Qdrant FAQ
What happens if I exceed the Free Tier limits?+
You can upgrade to a Standard Tier, which provides larger resources and dedicated clusters.
How does Qdrant Cloud pricing work?+
Pricing is usage-based; you pay for the compute, memory, storage, backups, and paid inference tokens your cluster consumes.
Can I migrate from OSS to Qdrant Cloud?+
Yes, Qdrant provides a migration tool and documentation to move an existing OSS deployment to the cloud.
How do I choose between Free and Standard tiers?+
Free Tier is for testing with limited resources; Standard Tier is for production workloads needing dedicated clusters and higher availability.
What’s the difference between Managed, Hybrid, and Private Cloud?+
Managed Cloud is fully run by Qdrant; Hybrid lets you use your own infrastructure with Qdrant’s control plane; Private Cloud offers isolated on-prem deployments.
How is billing calculated month-to-month?+
Billing is hourly based on actual resource usage (vCPU, memory, storage, backups, and inference tokens) and summarized monthly.
