## Choose when

### Choose sacred if…

- 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.

### Choose wandb if…

- Tags unique to wandb: ai, collaboration, deep-learning, hyperparameter-optimization.
- Also covers Evaluation & Observability.
- Need extensive collaboration features for teams working on deep-learning projects

## 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.

## When NOT to use wandb

- Looking for a lightweight solution without extensive collaboration features
- Focusing on simple models where detailed experiment tracking is unnecessary
- Operating within environments that strictly forbid third-party hosting solutions
