AI Website Auditor: A Full-Stack Intelligent Website Analysis Tool Combining Playwright and Groq

Introducing an open-source full-stack website auditing tool called AI Website Auditor. It combines Playwright's deep crawling of dynamic pages with Groq LLM's intelligent semantic analysis to address the pain points of traditional tools, such as insufficient static crawling and lack of intelligent insights. It offers real-time WebSocket streaming diagnostics and a glassmorphism UI experience, providing developers and website owners with a comprehensive website health diagnosis solution.

As web application complexity increases, dynamically rendered pages render traditional static crawlers ineffective. SEO optimization, content quality assessment, and accessibility testing require professional knowledge. AI Website Auditor was created to solve these issues: it deeply crawls dynamic pages and uses AI to generate intelligent audit summaries, making technical diagnostics more intuitive and understandable.

Frontend

Built with React + Vite, using Tailwind CSS v4 to implement glassmorphism design, paired with the Lucide React icon library and React Router v7 for routing.

Backend

Based on the FastAPI asynchronous framework, Playwright drives real browsers to render dynamic pages. A thread pool is encapsulated to solve Windows asynchronous process issues, ensuring cross-platform compatibility.

AI Layer

Combined with the LangChain framework and Groq API (Llama-3-8b model), it uses low-latency inference capabilities to perform semantic understanding of crawled data and generate readable audit summaries.

1. Deep Crawling: Playwright simulates user visits + BeautifulSoup parses DOM, supporting JavaScript-heavy pages.
2. Multi-dimensional Evaluation: SEO detection (titles/meta descriptions/hierarchy), content analysis (word count/keyword density), accessibility checks (alt text/semantic tags).
3. Real-time Streaming Diagnostics: WebSocket pushes audit progress (crawling → analysis) with visual feedback.
4. AI Intelligent Summary: Converts technical data into natural language summaries and improvement suggestions.
5. Persistent Storage: PostgreSQL + SQLAlchemy saves audit records, supporting historical queries and trend analysis.

Environment Requirements: Python 3.10+, Node.js, PostgreSQL, Groq API key. Backend Deployment: Create a virtual environment → install dependencies → configure .env (GROQ_API_KEY/DATABASE_URL) → start the service with Uvicorn. Frontend Deployment: Enter the frontend directory → npm install → npm run dev to start the development server.

Suitable for independent developers' pre-launch self-inspection, SEO practitioners' client website diagnosis, and internal quality monitoring by enterprise technical teams; the real-time streaming feedback feature is especially suitable for demo environments to intuitively display the audit process.

Open-sourced on GitHub under the MIT license, it demonstrates a reference architecture combining web technology and AI capabilities. Developers can expand detection dimensions or integrate other LLM providers.

AI Website Auditor represents a new direction in website auditing: shifting from technical detection to intelligent and visual comprehensive analysis. Playwright solves the problem of dynamic rendering, Groq provides low-latency AI inference, and WebSocket enables real-time interaction. In the future, it is expected to add screenshot visual analysis features supported by multimodal models.
