Facebook Sharing Debugger Alternatives: Tools for Checking Link Previews Across Platforms

Written by Proovd — proovd.in.

Last verified September 19, 2026. Meta’s Sharing Debugger still requires a Facebook login. Proovd does not scrape Facebook.

If you typed “sharing debugger” looking for Meta’s official tool, that is developers.facebook.com/tools/debug/. This page is about checking Open Graph on other platforms.

Need Facebook’s cache scraped?

Use Meta’s Sharing Debugger. Need to see Discord, Slack, LinkedIn, X, WhatsApp, or Reddit before you share? That is Proovd — not a Facebook clone.

Intent check

  • Facebook/Meta debugger → official Sharing Debugger (login required, Facebook only, can refresh Facebook’s scrape).
  • Multi-platform OG check → Proovd (no Facebook card, no Facebook cache clear).
  • LinkedIn cache → LinkedIn Post Inspector.

What Meta’s Sharing Debugger is for

Sharing Debugger previews how content looks when it is shared to Facebook and debugs Open Graph issues as Facebook sees them. If your job is “make this URL look right on Facebook / Instagram sharing,” start there. Third-party tools cannot issue Facebook’s scrape the way Meta can.

What it is not for

It will not tell you why Discord hid an embed, why Slack did not unfurl, or why LinkedIn is still showing last week’s image. Those crawlers are separate. Ranking for the query “sharing debugger” while answering “use us instead of Facebook” mismatches what people typed.

Platform coverage (honest)

LinkedIn Post Inspector — — — ✓ — —

Proovd also simulates a Reddit card. It does not clear any platform’s production cache. LinkedIn Post Inspector is still the right cache-bust for LinkedIn: linkedin.com/post-inspector.

Suggested workflow

  1. If the destination is Facebook, use Sharing Debugger and scrape again after you change tags.
  2. If you share the same URL in Slack, Discord, or LinkedIn, paste it into Proovd once and look at those previews together.
  3. If LinkedIn is stale after a fix, run Post Inspector, then re-check.
  4. We are not linking a Twitter/X “Card Validator” URL here; that endpoint has moved and is often gated. Treat X as another OG consumer and verify tags in the HTML.

Quick checklist

  1. Pick the platform you actually ship to — Facebook vs everywhere else.
  2. Facebook scrape → Meta debugger.
  3. Discord / Slack / LinkedIn / X / WhatsApp / Reddit preview → Proovd.
  4. LinkedIn still stale → Post Inspector.

Frequently asked questions

Is Facebook Sharing Debugger free?

Yes. It is a Meta developer tool. You must be logged into Facebook.

Does Proovd replace Sharing Debugger?

No. Different crawlers, different cache. Use both if you publish to Facebook and to chat apps.
