🤖 WebQA Agent is an autonomous web browser agent that audits performance, functionality & UX for engineers and vibe-coding creators. ✨

🚀 Core Features

🧭 Overview

📋 Feature Highlights

• 🤖 AI-Powered Testing: Performs autonomous website testing with intelligent planning and reflection—explores pages, plans actions, and executes end-to-end flows without manual scripting. Features 2-stage architecture (lightweight filtering + comprehensive planning) and dynamic test generation for newly appeared UI elements.
• 📊 Multi-Dimensional Observation: Covers functionality, performance, user experience, and basic security; evaluates load speed, design details, and links to surface issues. Uses multi-modal analysis (screenshots + DOM structure + text content) and DOM diff detection to discover new test opportunities.
• 🎯 Actionable Recommendations: Runs in real browsers with smart element prioritization and automatic viewport management. Provides concrete suggestions for improvement with adaptive recovery mechanisms for robust test execution.
• 📈 Visual Reports: Generates detailed HTML test reports with clear, multi-dimensional views for analysis and tracking.

📹 Examples

• 🤖 Conversational UI: Autonomously plans goals and interacts across a dynamic chat interface
• 🎨 Creative Page: Explores page structure, identifies elements

Quick Start

🏎️ Recommended uv (Python>=3.11):

# 1) Create a project and install the package
uv init my-webqa && cd my-webqa
uv add webqa-agent
uv sync

# 2) Install browser (required)
uv run playwright install chromium

# 3) Create a config file (auto-generated template)
uv run webqa-agent init            # creates config.yaml

# 4) Edit config.yaml
#    - target.url: your site
#    - llm_config.api_key: your OpenAI key (or set OPENAI_API_KEY)
#  For detailed configuration information, please refer to the "Usage > Test Configuration"

# 5) Run
uv run webqa-agent run

🐳 Docker (one-liner)

Before starting, ensure Docker is installed. If not, please refer to the official installation guide: Docker Installation Guide.

Recommended versions: Docker >= 24.0, Docker Compose >= 2.32.

mkdir -p config \
  && curl -fsSL https://raw.githubusercontent.com/MigoXLab/webqa-agent/main/config/config.yaml.example -o config/config.yaml

# Edit config.yaml
# Set target.url, llm_config.api_key and other parameters

curl -fsSL https://raw.githubusercontent.com/MigoXLab/webqa-agent/main/start.sh | bash

🛠️ From source

git clone https://github.com/MigoXLab/webqa-agent.git
cd webqa-agent
uv sync
uv run playwright install chromium
cp ./config/config.yaml.example ./config/config.yaml
# Edit config.yaml
# Set target.url, llm_config.api_key and other parameters
uv run webqa-agent run -c ./config/config.yaml

Notes for Running Tests

• Functional Testing (AI mode): Two-stage planning. Stage 1 (filter_model) prioritizes elements for efficient analysis; Stage 2 (primary model) generates comprehensive test cases. The agent may reflect and re-plan based on page state and coverage, so executed case count can differ from the initial request. When dynamic_step_generation is enabled, new UI elements (e.g., dropdowns, modals) detected via DOM diff will trigger additional generated steps.
• Functional Testing (default mode): Focuses on whether UI interactions (clicks, navigations) complete successfully.
• User Experience Testing: Multi-modal analysis (screenshots + DOM structure + text) to assess visual quality, detect typos/grammar issues, and validate layout rendering. Model outputs include best-practice suggestions for optimization.
