Paste a URL; a real Chromium browser loads it on desktop and mobile and checks what breaks launches: HTTP status, broken links, title / meta description / H1, Open Graph social previews, mobile viewport + horizontal overflow, console errors, load time, image alt text, favicon. You get a shareable report with screenshots and exact fixes. Works for humans (web, $3) and AI agents (MCP / REST).
