Why peeklink

Preview cards. Catch broken meta.

One paste, six platform mockups, and a clear checklist for Open Graph and Twitter Card tags.

Multi-platform cards

See approximate Discord, Telegram, X, Facebook, LinkedIn and Slack previews side by side.

OG & Twitter audit

We flag missing titles, thin descriptions, absent images and incomplete Twitter Card tags.

No account needed

Paste a public URL and get results instantly — free, in the browser.

Share-ready confidence

Ship links knowing what followers will actually see in the embed.

Any public page

Landing pages, blog posts, docs, product pages — if it’s public HTML, we can unfurl it.

SEO-friendly meta

Good previews and complete tags help both social CTR and how search engines understand your page.

How it works

Three steps to a clean preview

No extensions. No debugger logins. Just the URL.

  1. 01

    Paste the link

    Drop any public https URL into the checker.

  2. 02

    We read the meta

    Peeklink fetches the page and extracts Open Graph, Twitter Card and HTML tags.

  3. 03

    Fix what matters

    Use the score and checklist to add missing title, description or image tags.

Guide

How to improve your link preview

A quick checklist for marketers, founders and developers.

Step 1

Set og:title and og:description

Use a clear title and a 50–160 character description that works when truncated.

Step 2

Add a large og:image

Prefer ~1200×630 images. Absolute https URLs work best across platforms.

Step 3

Add twitter:card

summary_large_image is usually best for articles and product pages.

Step 4

Re-check after deploy

Paste the live URL into peeklink again — some networks cache previews aggressively.

Use cases

Built for people who share links

From launch posts to docs and support replies.

Product launches

Make sure your landing page card looks sharp on X, LinkedIn and Discord before you announce.

Content & SEO

Validate blog and docs pages so embeds don’t show a blank image or truncated nonsense.

Community & support

Check links before posting in Slack, Telegram or Discord so the embed matches the message.

Agencies & freelancers

Show clients a before/after of their social cards without logging into each platform debugger.

FAQ

Questions about link previews

Quick answers before you paste a URL.

Is peeklink.app free?

Yes. Checking public URLs is free and does not require an account.

Do you store the pages I check?

We fetch pages temporarily to extract meta tags. We don’t build a public archive of your URLs.

Why doesn’t my preview update on Discord/X?

Many platforms cache embeds. After you fix tags, you may need their debugger or to wait for cache expiry.

Is this the same as Facebook Sharing Debugger?

It’s a lightweight alternative: one place to preview multiple networks and audit OG/Twitter tags without logging in.

Can you check private or localhost URLs?

No. Only publicly reachable http(s) pages are supported — private networks are blocked for safety.

Will the mockups look identical to each app?

They’re close approximations. Platforms change styling; use them to catch missing content, not pixel-perfect design QA.
