# WebMMU: The Web Multimodal Understanding Benchmark
WebMMU is a comprehensive benchmark designed to push the boundaries of AI for the web. It challenges models to answer questions about websites, edit real HTML/CSS/JS code, and generate web layouts from mockups—across four languages and 20+ domains. Whether you're building smarter web agents or testing the limits of multimodal models, WebMMU is your go-to testbed.
## Key Features
- 🌐 **Multilingual:** English, Spanish, German, French
- 🧩 **Three Core Tasks:** WebQA, Code Editing, Mockup2Code
- 🖥️ **Real-World Data:** 20+ website domains
- 🔍 **Fine-Grained Evaluation:** Web Understanding & Reasoning, Agentic UI Action, and Code Generation
- 🤝 **Open & Human-Annotated:** Expert-verified, high-quality samples
---
## Tasks Overview
### WebQA
Answer questions about real website screenshots—test your model's ability to reason, ground, and understand UI elements and content.
### Mockup2Code
Turn hand-drawn or digital mockups into working HTML/CSS code. Evaluate how well your model translates design into code.
### Code Editing
Edit real website code based on user instructions. Can your model make precise, functional changes to HTML, CSS, or JS?
