Milvus pricing guide details
Pricing Overview
Milvus operates as a fully open-source vector database under the Apache 2.0 license, meaning the core software is free to download, deploy, and use without licensing fees. Organizations can run Milvus Lite for prototyping, Milvus Standalone for single-machine production workloads, or Milvus Distributed for enterprise-grade horizontal scaling across billions of vectors. For teams that prefer a managed service, Zilliz Cloud offers fully managed Milvus with serverless and dedicated cluster options, plus BYOC deployment for security-sensitive environments. Self-hosted Milvus carries zero software cost but requires infrastructure investment in compute, storage, and engineering time for operations. Zilliz Cloud pricing is usage-based and requires contacting sales for a custom quote.
Plan Comparison
Milvus provides four distinct deployment models, each targeting a different stage of the adoption lifecycle.
| Deployment | Cost | Scale | Best For |
|---|---|---|---|
| Milvus Lite | Free | Millions of vectors | Learning, prototyping, notebook environments |
| Milvus Standalone | Free (self-hosted) | Millions of vectors | Production or testing on a single machine |
| Milvus Distributed | Free (self-hosted) | Tens of billions of vectors | Enterprise workloads requiring horizontal scaling and high availability |
| Zilliz Cloud | Custom quote | Tens of billions of vectors | Teams wanting fully managed infrastructure with SaaS or BYOC options |
Milvus Lite runs as a lightweight library installed via pip, making it the fastest path to evaluation. Milvus Standalone delivers a complete single-node deployment suitable for datasets up to millions of vectors. Milvus Distributed separates storage and computation with a stateless, cloud-native architecture that scales horizontally. Zilliz Cloud removes all operational overhead and advertises 10x quick performance compared to self-managed Milvus, with both serverless and dedicated cluster configurations available.
Hidden Costs and Considerations
Self-hosted Milvus deployments require Kubernetes orchestration for the Distributed edition, which demands dedicated DevOps expertise. Infrastructure costs for compute nodes, persistent storage, and network egress scale with data volume. Monitoring, backup, and disaster recovery must be built and maintained by your team. Zilliz Cloud eliminates these operational burdens but locks you into a managed service contract. Data migration between self-hosted and cloud deployments requires careful planning around index compatibility.
How Milvus Pricing Compares
Milvus competes in the vector database category against both open-source and SaaS-first alternatives. Its open-source core provides a cost advantage for teams with infrastructure expertise.
| Vector Database | Pricing Model | Starting Price | Free Tier |
|---|---|---|---|
| Milvus | Open Source / Enterprise | $0 (self-hosted) | Full open-source edition |
| ChromaDB | Usage-Based | $0 | Free tier; paid from $5/mo |
| Qdrant | Freemium | $0 | Free tier; paid from $1/mo |
| Pinecone | Usage-Based | $0 | Free tier; paid from $0.15/hr for 4 cores |
Milvus stands apart by offering unlimited self-hosted usage at zero software cost. ChromaDB provides usage-based pricing starting at $5/mo for smaller workloads. Qdrant follows a freemium model with paid plans beginning at $1/mo. Pinecone charges $0.15 per hour for a 4-core pod, making it consumption-based from the start. For organizations with existing Kubernetes infrastructure, Milvus Distributed delivers enterprise-grade vector search without per-query or per-vector fees.
