If I (as a Gradio founder) can offer a different perspective: most apps on Hugging Face Spaces are not designed for production-level traffic. Instead, it might be a researcher who wants to share a demo of their model for reproducibility purposes, a student who's built a class project, or a hobbyist interested in building out a portfolio. For most of these projects, writing a simple gradio application and hosting on Spaces is the easiest way to share their machine learning model.
