## Choose when

### Choose mlem if…

- Tags unique to mlem: cli, data-science, deployment, git.
- Also covers Developer Tools.
- Use MLEM if you are looking to deploy ML models quickly using a command-line interface (CLI), making it ideal for teams preferring script-driven integration.

### Choose mlflow if…

- Tags unique to mlflow: agentops, agents, ai-governance, evaluation.
- Also covers Evaluation & Observability, Model Training.
- - Use when you're working with a diverse range of environments like local or cloud platforms because MLflow is **vendor-neutral**.

## When NOT to use mlem

- Avoid MLEM if you are working in environments where strict package dependency management is required outside Python, as it might complicate integration with non-Python native services.
- If detailed manual configuration of deployment settings is a necessity for your application, consider alternatives that offer more granular control over model serving parameters and configurations.

## When NOT to use mlflow

- - Avoid if your organization has strong preferences for proprietary solutions with advanced features not available in the open-source domain.
- - Not recommended for users who prefer a fully managed service without self-hosting options, as competitors like Databricks or Azure ML offer integrated services tailored for their cloud environments.
