Why does Meta Preview run on the server?
Fetching arbitrary websites directly from a browser is often restricted by cross-origin policies. Server-side retrieval also allows BOYGR Tools to validate destinations and safely inspect HTML metadata.
Preview website metadata and social sharing information.
Meta & Open Graph Preview inspects common HTML metadata from a public webpage, including page title, description, canonical URL, Open Graph tags, and Twitter card metadata.
Open Graph tags help websites describe how pages should appear when shared on compatible social platforms and messaging applications. Twitter card metadata provides similar information for supported Twitter/X previews.
BOYGR Tools validates requested URLs before fetching them. Localhost, private networks, link-local addresses, reserved address ranges, unsupported protocols, and unsafe redirects are rejected by the Meta Preview backend.
Unlike browser-only utilities, this tool sends the requested public URL to the BOYGR Tools server. The server retrieves a limited HTML response, extracts metadata, and returns the parsed values to the browser.
Fetching arbitrary websites directly from a browser is often restricted by cross-origin policies. Server-side retrieval also allows BOYGR Tools to validate destinations and safely inspect HTML metadata.
Not every webpage provides every metadata tag. A page may omit Open Graph, Twitter, canonical, or description metadata.
Some websites block automated requests, require authentication, use bot protection, or return metadata only after client-side JavaScript executes.
No. Private, localhost, link-local, and reserved network destinations are intentionally blocked to reduce server-side request forgery risks.
