Rio is a Python framework for building web applications and websites without writing HTML, CSS, or JavaScript.
Rio addresses the friction of full-stack web development by letting Python developers build complete applications using only Python code. It brings a component-based architecture inspired by React to Python, where developers compose built-in UI components into custom components and then into full applications. The framework handles the translation to web technologies internally, eliminating the need to context-switch between languages or manage separate frontend and backend codebases.
Rio suits Python developers building data applications, dashboards, and internal tools who want to avoid learning web technologies. It works well for data science and machine learning projects where the primary logic is already in Python and a web interface is needed. The framework supports both local execution and web deployment from the same codebase, making it practical for prototyping locally before publishing online.
The project shows consistent development activity with regular updates to its codebase. The maintainers actively engage with the community through a dedicated Discord channel. Documentation is maintained across tutorials, examples, and API references. The project continues to expand its component library and improve the developer experience based on community feedback.
