Social Preview
Preview how a URL unfurls on social platforms and audit its meta tags.
A link that unfurls with a missing image or a cut-off title is easy to ship and hard to notice. Enter a URL and Social Preview fetches its Open Graph and Twitter Card tags, draws the card as ten platforms would show it, and audits the tags against common best practices. The fetch comes from your own machine, which also works for staging pages you can reach.
Ten platform previews
See mock-ups for X, Bluesky, Facebook, LinkedIn, Discord, Slack, Reddit, WhatsApp, Telegram and Google Search. Toggle platforms on or off.
Fallback chains applied
The effective title, description and image follow fallbacks such as og:title, then twitter:title, then the HTML title tag.
Audit with pass, warn and fail
Checks cover the HTTP status, title and description length, image presence and HTTPS, twitter:card, og:url, canonical link, site name, type, favicon and theme colour.
Image size and weight
The tool downloads the preview image to read its dimensions and file size, and flags sizes below the recommended 1200x630 or files that are too heavy.
Raw tag table
Open the list of every Open Graph and Twitter tag found on the page, in document order.
Is the preview exactly what each platform shows?
It is a close mock-up built from the page's tags. Platforms cache cards and change their layouts, so treat the previews and audit as a guide and re-scrape on the platform when you need the live result.
Can I preview a page that returns an error?
Yes. Pages such as a 404 that still contain meta tags are parsed, and the audit flags the HTTP status as a problem.
