Vision2Web is a comprehensive benchmark designed to evaluate multimodal coding agents on **visual website development tasks spanning the full software development lifecycle**.

This dataset repository contains the **benchmark tasks, UI prototypes, test workflows, and resources** used to evaluate agent performance.

---

# 👀 Introduction

Vision2Web is a hierarchical benchmark for evaluating multimodal coding agents on **end-to-end visual website development**, measuring their ability to integrate:

- UI understanding
- requirements reasoning
- interactive logic
- full-stack implementation

in **long-horizon development scenarios**.

</p>

The benchmark is organized into three progressive levels:

### Level 1 – Static Webpage

Generate responsive executable webpages from multi-device UI prototypes  
(desktop / tablet / mobile).

**Metric**

- Visual Score (VS)

---

### Level 2 – Interactive Frontend

Develop multi-page interactive frontends from multiple prototypes and textual specifications.

**Metrics**

- Visual Score (VS)
- Functional Score (FS)

---

### Level 3 – Full-Stack Website

Build complete full-stack web systems from requirement documents and UI prototypes.

Agents must implement:

- backend logic
- state management
- frontend interactions

**Metrics**

- Visual Score (VS)
- Functional Score (FS)

---

Evaluation uses a **workflow-based agent verification paradigm** combining:

- **GUI Agent verifiers** for functional correctness
- **VLM-based judges** for visual fidelity

This enables **scalable and implementation-agnostic evaluation** across increasing levels of complexity.

---

# 📥 Using the Dataset

The dataset can be downloaded directly from Hugging Face.

After downloading, extract the dataset and place it in your project directory with the following structure:

```

datasets/
├── webpage/    # Level 1: Static Webpage (100 tasks)
├── frontend/   # Level 2: Interactive Frontend (66 tasks)
└── website/    # Level 3: Full-Stack Website (27 tasks)

```

Each task directory contains the following components:

| File / Folder | Description |
|---|---|
| `prototypes/` | UI prototype images (desktop / tablet / mobile) |
| `resources/` | Multimedia assets used in tasks |
| `workflow.json` | Functional test workflow specification |
| `prompt.txt` | Textual requirements (Level 2 only) |
| `prd.md` | Requirement document (Level 3 only) |

Once extracted, ensure the dataset directory is placed at the root of the Vision2Web project so that the evaluation pipeline can locate the benchmark tasks correctly.
