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?
