Create web-based user interfaces with Python, featuring a backend-first approach and rich interactive elements.
NiceGUI is a Python-based UI framework that allows developers to create web-based graphical user interfaces directly from Python code. It provides a rich set of interactive components like buttons, plots, 3D scenes, and dashboards, which render in a web browser without requiring frontend expertise. The framework solves the problem of building interactive web apps quickly, especially for data visualization, device control, and internal tools.
Python developers, data scientists, robotics engineers, and IoT practitioners who need to build interactive web interfaces, dashboards, or control panels without deep frontend knowledge.
Developers choose NiceGUI for its backend-first approach, which keeps all logic in Python while delivering a modern web UI. It offers more control and less 'magic' than alternatives like Streamlit, with real-time updates, extensive component library, and flexible deployment options including self-hosting.
Create web-based user interfaces with Python. The nice way.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Offers a wide array of elements from basic buttons to advanced 3D scenes and plots, as listed in the features, reducing the need for external libraries.
Keeps all UI logic in Python using FastAPI, eliminating frontend expertise requirements and speeding up prototyping for Python developers.
Built-in WebSocket support and timers enable live data updates and responsive interfaces, ideal for dashboards and control panels.
Runs as a webserver, in native desktop windows, or within Jupyter Notebooks, catering to diverse environments from development to production.
Deep styling or behavior changes require understanding of the underlying Vue/Quasar framework, which can be complex despite Tailwind auto-complete.
WebSocket-based communication for all UI events may introduce latency and scalability challenges in high-concurrency scenarios.
Tightly coupled with specific technologies like Vue and Quasar, making migration or integration with other stacks more difficult.
