SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Mesop lets developers build web UIs for Python apps without writing HTML, CSS, or JavaScript, speeding UI delivery for AI demos and internal tools.

Core Features & Use Cases

  • Pure-Python UI definitions with components like me.box, me.text, me.input
  • Serializable per-session state via @me.stateclass and state objects
  • Flexible event handling (regular, generator/streaming, and async)
  • Styling and layout with me.Style and responsive box/grid patterns
  • Deployment targets: Cloud Run, Docker, and Hugging Face Spaces
  • Use Case: rapidly prototype internal dashboards and data-science demos directly in Python.

Quick Start

Install mesop and create a main.py with a page entry to launch your first Python-native web UI.

FAQPage Schema
How do I build a web UI in Python without writing any frontend HTML, CSS, or JavaScript?

You can build a Python-native web UI without writing frontend HTML, CSS, or JavaScript by using pure-Python UI definitions with components like me.box, me.text, and me.input. This allows rapid UI creation directly in Python for internal tools and AI demos.

How does per-session state management work in Python web UI frameworks?

Per-session state management in Python web UIs is handled via serializable @me.stateclass objects. This ensures individual user sessions maintain isolated state, which is critical for interactive dashboards and data-science demos.

Can I deploy Python-native web apps to Docker or Cloud Run?

Yes, you can deploy Python-native web apps to Docker, Cloud Run, or Hugging Face Spaces. This allows flexible deployment of internal tools and AI demos built with pure-Python UI definitions.

Does this Python UI framework support streaming event handlers for AI demos?

Yes, this Python UI framework supports flexible event handling for AI demos, including regular, async, and generator/streaming event handlers. This enables dynamic UI updates directly from Python.

What is the best way to style and layout a Python web UI without CSS?

The best way to style and layout a Python web UI without CSS is using me.Style along with responsive box and grid patterns. This provides complete styling control directly within pure-Python code.

Why use a Python-native UI framework instead of traditional frontend code for internal dashboards?

Use a Python-native UI framework for internal dashboards to speed up UI delivery by eliminating HTML, CSS, and JavaScript. This allows Python developers to rapidly prototype and deploy interactive tools without frontend overhead.
