About this tool
Website Checker is a static, client-side tool with no backend. Website Checker is a free SEO Audit utility that runs in your browser, doing its work on the input you provide without a backend.
Because it runs on your device, it is fast and private and works offline once loaded. Your input never leaves the page, and no account or install is required.
