Does this look exactly the same as it does on KakaoTalk or Facebook?

Not exactly — each platform has its own caching policy and rendering style, so the visual details may differ, but the extracted og: tag values themselves are the same.

What happens if there are no OGP tags?

If no og: tags are found, "No tags found" is shown — in that case, most social platforms fall back to inferring the page's title and description instead.

Is the URL I check stored?

No. Every request is checked immediately and nothing is stored.

Card shows old content?

The platform cached it — refresh via Facebook Sharing Debugger or Twitter Card Validator.

What if og:image is small?

Platforms have minimum sizes — the card may not render. 1200×630px is recommended.

Entering a URL extracts that page's og: meta tags and shows them alongside a social share card preview. The values above are an illustrative sample and will vary with the tags present at the time you check.
