## Choose when

### Choose zvec if…

- zvec is primarily C++; azure-search-vector-samples is Jupyter Notebook.
- License: zvec is Apache-2.0, azure-search-vector-samples is MIT.
- Pricing: Open-source under Apache-2.0 license; free to use and modify for personal or commercial purposes..
- Requirements: Min 1 GB RAM; Minimum RAM requirement corresponds to recommended system resources for optimal performance without overburdening the host environment..
- Tags unique to zvec: agent-skills, db, embedded, faiss.
- Ideal for applications that require ultra-fast searching capabilities within an embedded solution.

### Choose azure-search-vector-samples if…

- azure-search-vector-samples is primarily Jupyter Notebook; zvec is C++.
- License: azure-search-vector-samples is MIT, zvec is Apache-2.0.
- Tags unique to azure-search-vector-samples: azure, azurecognitivesearch, embeddings, vector-search.
- When developing applications that require advanced semantic search functionalities on unstructured data within the Microsoft ecosystem, as it integrates seamlessly with Azure resources

## When NOT to use zvec

- Not recommended if your project requires Python versions outside of 3.10-3.14 for its Python SDK.
- If you need a distributed vector database that operates across multiple nodes or services, zvec’s in-process and embedded nature may be restrictive.
- Consider alternatives if Zvec's current language support (Python, Node.js, Go, Rust, Dart/Flutter) does not align with the languages used in your project.

## When NOT to use azure-search-vector-samples

- When working in non-Microsoft cloud environments due to its tight integration with Azure services
- For users who require real-time processing capabilities, as Azure AI Search might not be optimized for low-latency queries compared to specialized vector databases
