Description
OpenGraph Fallback Embed adds a custom Gutenberg block and an auto-embed fallback that renders rich link cards using OpenGraph metadata from any URL.
Features:
- OpenGraph Embed block — Paste any URL to embed it as a styled card showing the page’s title, description, image, and site name.
- Auto-embed fallback — When WordPress can’t find an oEmbed provider for a URL pasted on its own line, this plugin automatically fetches the page’s OpenGraph tags and renders a card instead of a plain link.
- Graceful degradation — Falls back to Twitter Card meta tags, then to HTML
<title>and<meta name="description">when OpenGraph tags are missing. - Transient caching — Fetched metadata is cached for 7 days to minimise external requests.

FAQ
-
The plugin falls back to Twitter Card meta tags, then to the page’s
<title>and<meta name="description">. If none of these are available, the original WordPress output is preserved. -
Does this override existing embed providers?
-
No. This plugin only activates when WordPress has no other embed handler for the URL.
-
Can I customise the card appearance?
-
The card uses the
.og-fallback-embedCSS class. You can override styles in your theme.
