Social Preview & OG Tag Checker for Lovable Apps

Paste any URL to see realistic link-preview mockups for LinkedIn, X, Facebook, Slack and iMessage, built from the page's Open Graph and Twitter tags. A pass/warn/fail checklist covers title and description length, og:image size and absolute URLs, and flags pages that look empty to crawlers. You get a copyable 'Fix it in Lovable' prompt and corrected meta tag HTML. Free, no signup. Built by Cogny, the AI marketing analytics platform. Not affiliated with Lovable, LinkedIn, X or Meta.
