## Choose when

### Choose aim if…

- License: aim is Apache-2.0, sacred is MIT.
- Tags unique to aim: ai, data-science, experiment tracking, mlflow.
- Also covers Evaluation & Observability.
- You are working on Python-based machine learning projects and need detailed experiment tracking to manage metadata effectively.

### Choose sacred if…

- License: sacred is MIT, aim is Apache-2.0.
- Pricing: Being an open-source tool under the MIT license, Sacred can be used freely without any cost..
- Tags unique to sacred: config injection, experiment management, logging, reproducibility.
- Also covers Developer Tools.
- When precise control over experiment configurations and their dependencies is required, allowing consistent reproduction of results.

## When NOT to use aim

- You prefer comprehensive pre-built integrations with cloud services for MLOps processes that are not natively extensive in Aim.
- Your project is primarily coded in languages other than Python; while language versatility might be desired, Aim specifically excels within the Python ecosystem.

## When NOT to use sacred

- If your project does not require deep integration with MongoDB for logging purposes, as Sacred assumes this setup out-of-the-box without offering as much flexibility to other storage options.
- When you need a tool with lightweight overhead, since Sacred's comprehensive feature set introduces more complexity suitable only for larger-scale projects.
