Check OG and Twitter cards before sharing a URL
Link Preview Checker helps inspect a blog post, product page, landing page, or documentation URL before sharing. It fetches page metadata server-side, then shows the social card preview, detected Open Graph/Twitter tags, and missing or weak fields.
Useful For
- Preview links before sharing in Slack, X, Facebook, or LinkedIn
- Check missing og:title, og:description, and og:image
- Verify a live page after generating SEO meta tags
Good To Know
Some websites may block bots, require login, geo-restrict content, or cache previews differently from social platforms.
Developer Check
Generated code, regexes, meta tags, and config snippets should be treated as drafts and tested again in your runtime, security policy, and deployment environment.
