Netron

Netron is a browser-based visualizer for neural network, machine learning, and deep learning model architectures.

About Netron

Netron is a viewer for neural network models that runs entirely in your browser. You drag in a model file and it renders the full network graph, showing every layer, node, and tensor operation. It supports ONNX, TensorFlow Lite, Keras, Caffe, Darknet, MXNet, PyTorch, and many other formats.

Built by Lutz Roeder, Netron works offline after the page loads because the parsing happens client-side. The GitHub repository also provides a standalone Electron desktop app for Windows, macOS, and Linux. It handles models up to several hundred megabytes, with search, zoom, and export features built in.

Netron is open source under the MIT license and completely free. Anyone debugging or documenting a model architecture will find it useful. Researchers, ML engineers, and students often use it to inspect pretrained models without setting up a full training environment.
