PreviewProof
Built for apps that deserve to spread

See your link the waythe internet sees it

Paste a public URL. We fetch it the way sharing bots do, with no JavaScript, then show you the previews your tags produce and how to fix what's missing.

Try:

Public pages only. We don't keep the pages you check; recent checks stay in your browser.

How it works

Fetch like a bot

We request your page the way Slack, X and LinkedIn do: no JavaScript, a strict time limit, and redirects followed.

See every preview

Google, X, LinkedIn, Slack and iMessage/WhatsApp cards rendered from your real tags, with each platform's fallbacks.

Fix it in one paste

Each issue comes with the exact HTML and a prompt you can paste straight into Lovable, or copy everything at once.

What we check

The things that quietly turn a share into a bare blue link.

  • Pages that are blank until JavaScript runs
  • Preview image: present, loads, is an image, not too heavy
  • Title and description: present, not placeholders, right length
  • Open Graph and X card tags
  • noindex in meta tags or X-Robots-Tag
  • Canonical URL and redirects
  • Slow first responses that make bots give up
  • Stock template images and default titles
