Mesop

Mesop: The open-source Python UI framework for rapidly building scalable web applications, especially AI/ML demos and internal tools.

Mesop is a declarative, component-based UI framework that lets Python developers build full web applications using pure Python code: no required HTML, CSS, or JavaScript. Developed by a team at Google, it targets engineers without extensive frontend experience (e.g., data scientists, ML engineers) who need fast visualization and deployment. Installation is simple: `pip install mesop`. The framework focuses on velocity, making it ideal for rapid prototyping and creating user-friendly internal apps, a use case validated by its adoption across dozens of teams within Google for their own internal tooling.
