Show HN: Emmtrix ONNX-to-C Code Generator for Edge AI Deployment
emx-can Tuesday, February 03, 2026
Hi HN, we wanted to share our open source ONNX-to-C code generator. It translates ONNX models into C code for deployment on embedded systems. We developed it for use with emmtrix Code Vectorizer (https://www.emmtrix.com/tools/emmtrix-code-vectorizer) which optimizes the generated code for various embedded architectures. The ONNX-to-C code generator can however also be used standalone to generate plain C code. In contrast to many other tools, it makes deployment trivial since the generated code is fully standalone and no additional runtime is required.
Summary
The article discusses the emx-onnx-cgen project, which is a tool that generates C++ code from ONNX models, enabling efficient deployment of machine learning models on embedded systems and edge devices.
