What is a Share Debugger?

It's a tool that fetches a URL's HTML, reads its Open Graph (og:) and Twitter Card meta tags, and shows a mock-up of how the link will look when pasted into Facebook, X, KakaoTalk, Threads, Naver Blog, or WordPress.

Why does my link look different on each platform?

Each platform reads different tags (og:title vs twitter:title), truncates text at different lengths, and uses different layouts for the thumbnail image. This tool renders those layout differences side by side so you can catch problems before sharing.

Why is my image or title missing?

Most likely the page is missing an og:image, og:title, or og:description tag, or the page requires JavaScript to render its content, since crawlers only read the initial HTML.

Does this tool store the URLs I check?

No. The URL is fetched server-side to read its meta tags and the result is returned directly to your browser. Nothing is stored.

Why doesn't the preview match exactly what I see on Facebook or X?

Platforms sometimes cache a previously fetched preview or apply their own image cropping. This tool reflects the current meta tags on the page; if a platform shows a stale preview, use that platform's own cache-refresh tool after fixing your tags.
