Quick Start

1. Clone the repository

git clone https://github.com/OriLevin55/siteaudit-pro.git
cd siteaudit-pro

2. Create a virtual environment

python -m venv venv
source venv/bin/activate        # macOS/Linux
venv\Scripts\activate           # Windows

3. Install dependencies

pip install -r requirements.txt

4. Run the application

python app.py

Open your browser and navigate to http://localhost:5000.

How It Works

1. User enters a website URL
2. The Flask backend fetches the page and runs six audit modules
3. Each module returns a score (0–100) and individual check results
4. Scores are combined using a weighted average into an overall health score
5. Results are displayed with animated cards, a circular score ring, and status badges
