About OG Scope

What it is for

OG Scope is a set of small developer tools. Most of them take a public URL, fetch that page on the server, and report what the HTML publishes: Open Graph and Twitter card tags, the title and meta description, the canonical URL, redirects, or the pages a crawler can reach. The two image tools work on a file from your device instead.

• Open Graph Checker: Check a public URL. Estimated cards, a metadata table, an HTML export, an OG image check, and a checklist.
• Meta Tag Checker: Title, meta description, canonical URL, robots, viewport, language, H1, and Open Graph and Twitter tags from the public HTML.
• SERP Preview: Estimated Google title and description on desktop or mobile, with pixel width, a date or product prefix, and a rich snippet line.
• OG Image Size: Crop and resize an image in the browser to 1200 × 630 or another Open Graph size, then download PNG, JPG, or WebP.
• OG Image Generator: Create a 1200 × 630 share image from a template, a title, colors, and a logo, then download PNG, JPG, or WebP.
• Redirect Checker: Follow one URL or up to 1,000 in bulk, hop by hop, as a browser, Googlebot, or a link preview bot, with each status code and the final URL.
• XML Sitemap Generator: Crawl up to 20,000 pages and download sitemap.xml, a sitemap index for large sites, image tags, and a broken link report.
• XML Sitemap Validator: Check sitemap.xml, a sitemap index, or a text sitemap for XML errors, bad URLs, invalid lastmod dates, and size limits.

The guides explain the tags behind those results, from what Open Graph is to WhatsApp link previews. All of them are listed on the guides page.

What it does not do

It does not sign you in, and it does not keep a history of searches. A successful Open Graph or meta tag check may be kept for about ten minutes so the same URL is not downloaded again immediately. Failures are not kept, and the cache is not a permanent record. Redirect checks and sitemap crawls are not cached; a sitemap crawl lives in your browser tab until the tab is closed.

Images opened in the OG image generator or the OG image size tool stay in the browser. They are not uploaded to the server.

The server will not request localhost, private network addresses, or link-local addresses such as cloud metadata endpoints. Redirects are checked again before they are followed. The raw HTML of the target page is not sent to your browser.

The OGScopeBot crawler

Requests from the server identify themselves as OGScopeBot/1.0, with a link to this page. The redirect checker can also send the user agent of a browser, a search crawler, or a link preview bot when that option is chosen. The sitemap generator reads robots.txt first and, by default, skips the paths it disallows and follows its crawl delay. The person running the crawl can turn that setting off. A request is made only when someone runs a check on that URL.

Limits worth knowing

The cards are estimates. They are not screenshots of Facebook, LinkedIn, X, WhatsApp, Slack, Discord, or Telegram, and this site is not affiliated with those companies. Tags injected only by JavaScript will not appear. A site can also block the request. Each visitor can run a limited number of checks per minute.

How the guides are checked

The guides are published by Abid Ali, who maintains the site. A description of the tags on a public page can be checked again with the tool that guide names. The Open Graph checker, the meta tag checker, the redirect checker, and the sitemap tools read the public response. A card on this site is an estimate from that response. It is not a screenshot of Facebook, LinkedIn, X, Slack, Discord, WhatsApp, or Telegram.

A sentence about what a platform's documentation says is tied to the official page linked beside it. Sample tags in a guide are examples of markup. When a guide names a public URL it fetched, that URL is the page that was read.

A correction goes to the contact page or to abid.saeed.ali92@gmail.com. Name the guide and the sentence. The updated date on a guide is the date its text last changed. The published date stays the day the guide first appeared.
