Milvus
Milvus is an open-source vector database that accepts embeddings and returns similarity search results. You can run it locally for notebooks or single-node testing, deploy a distributed cluster for very large collections, or use the managed Zilliz Cloud for serverless or dedicated hosting.
The linked official pages do not list plan prices.Is Milvus right for you?
Good for
- Teams building GenAI or similarity-search features who want a vector DB that can run locally for prototyping and scale to distributed clusters for very large datasets.
- Open-source vector database positioned for GenAI and similarity search.
- Can scale from local prototyping to tens of billions of vectors using distributed deployment.
Keep in mind
- The lightweight 'Lite' option is explicitly described as for learning and prototyping, not production workloads.
- Standalone deployment is described as suitable up to millions of vectors, suggesting single-node capacity limits.
- Buyers who require published list prices or a guaranteed single-node capacity beyond “millions of vectors” without verifying capacity and pricing with the vendor first.
Pricing and plan limits
The source describes deployment options including a managed Zilliz Cloud and local/standalone/distributed installs but does not provide currency amounts, billing cadence, or plan names tied to prices. You must request pricing details from the vendor.

Standalone deployment is described as suitable up to millions of vectors, suggesting single-node capacity limits.
Choosing a plan
Assess Milvus by testing the 'Lite' local install for your prototype, then validate target dataset size and ask Zilliz for exact capacity and pricing for managed or distributed deployments before production roll‑out.
