## Choose when

### Choose scikit-learn if…

- scikit-learn is primarily Python; FeatherCNN is C++.
- Tags unique to scikit-learn: data-science, machine-learning, data-analysis, python.
- More GitHub stars (67k vs 1.2k) - visibility, not fit.

### Choose FeatherCNN if…

- FeatherCNN is primarily C++; scikit-learn is Python.
- Tags unique to FeatherCNN: android, arm-neon, c++, inference-engine.
- Also covers Inference & Serving.

## When NOT to use scikit-learn

- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.

## When NOT to use FeatherCNN

- Last GitHub push was 2483 days ago (dormant maintenance, Sep 24, 2019). Validate activity before betting a new project on FeatherCNN.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
