Overview of Current Alternatives
| Project | Stars | Maintenance | Language | License | Best for |
|---|---|---|---|---|---|
| TensorFlow Lite | 89,406 | ✅ actively maintained | C/C++ and Python | Apache-2.0 | Integration into TensorFlow ecosystem |
| ONNX Runtime | 25,954 | ✅ actively maintained | C++ & others | MIT | Cross-framework model inference across multiple ecosystems |
| MNN | 20,295 | ✅ actively maintained | C++ | Apache-2.0 | Mobile-focused inference with strong performance metrics |
Verdict
While ncnn (with its 23,505 stars and recent updates) is still a robust contender for developing on mobile platforms, leveraging frameworks like TensorFlow Lite or ONNX Runtime could provide you with broader support and more extensive toolsets, especially if you're deploying diverse model types or transitioning between different frameworks.
If you're already entrenched in a particular ecosystem (e.g., TensorFlow), TensorFlow Lite is a sound choice. For a more universal solution, ONNX Runtime shines, while MNN offers solid performance tailored specifically for mobile inference.
In conclusion, while ncnn is a highly efficient option, these alternatives can provide additional flexibility and support — choose based on your specific project requirements and existing technology stack.
