Facebook Sharing Debugger (and the related Meta content tools) scrape a URL and show the Open Graph tags Facebook stored. Nothing else fully replaces that cache refresh. You can still diagnose most failures without it.
What is a Facebook Sharing Debugger alternative?
For diagnosis, use View Source plus the Link Preview Checker to confirm absolute og:image before you scrape. For cache refresh, Sharing Debugger remains the official step. Treat “alternatives” as the checklist that makes Debugger succeed on the first try.
What size should a Facebook link preview image be?
Use 1200×630 as the working default. Details: Facebook image sizes.
| Goal | Use |
|---|---|
| See tags bots receive | View Source / link preview checker |
| Create the PNG | OG Image Generator |
| Clear Facebook cache | Sharing Debugger scrape |
| Related chat previews | WhatsApp guide |
Workflow
- Fix relative URLs, client-only meta tags, and blocked image hosts.
- Prefer a new image path when you change artwork.
- Confirm 200 on the image URL without cookies.
- Scrape the page URL in Sharing Debugger (not only the image URL).
- Reshare or wait for clients that still hold an old card.
