Compare NiceGUI vs. Streamlit

NiceGUI is an open-source library designed for Python that empowers developers to craft web-based graphical user interfaces (GUIs) using solely Python code. It boasts an approachable learning curve and simultaneously allows for sophisticated customizations. Adopting a backend-first approach, NiceGUI takes care of all web development intricacies, enabling developers to concentrate on their Python code. This framework is well-suited for diverse applications, from simple scripts and dashboards to robotics, IoT systems, smart home automation, and machine learning initiatives. It is constructed on FastAPI for backend functions, utilizes Vue.js for frontend interactions, and incorporates Tailwind CSS for styling aesthetics. With NiceGUI, developers can effortlessly create various elements, including buttons, dialogs, Markdown content, 3D visualizations, plots, and much more—all within a Python-centric environment. Furthermore, it facilitates real-time interactivity via WebSocket connections, allowing for immediate updates in the browser without needing to refresh the page. Additionally, NiceGUI provides a plethora of components and layout configurations, like rows and columns, ensuring versatile design possibilities for users.

Streamlit is the quickest way to create and distribute data applications. It allows you to transform your data scripts into shareable web applications within minutes, all using Python and at no cost, eliminating the need for any front-end development skills. The platform is built on three core principles: first, it encourages the use of Python scripting; second, it enables you to construct an application with just a few lines of code through an intuitively simple API, which automatically updates when the source file is saved; and third, it simplifies interaction by making the addition of widgets as straightforward as declaring a variable, without the necessity to write a backend, define routes, or manage HTTP requests. Additionally, you can deploy your applications immediately by utilizing Streamlit’s sharing platform, which facilitates easy sharing, management, and collaboration on your projects. This minimalistic framework empowers you to create robust applications, such as the Face-GAN explorer, which employs Shaobo Guan’s TL-GAN project along with TensorFlow and NVIDIA’s PG-GAN to generate attributes-based facial images. Another example is a real-time object detection app that serves as an image browser for the Udacity self-driving car dataset, showcasing advanced capabilities in processing and recognizing objects in real-time. Through these diverse applications, Streamlit proves to be an invaluable tool for developers and data enthusiasts alike.
