Allows to define shortcodes for easy replacement. Handy for recurrent copy/paste’s from sites like YouTube or DailyMotion… But not only. You decide! Also allows you not to write un-valid tags that would be stripped out by WordPress (<code><object></code>s for example)
The syntaxt is Shortcodes’ one, but for legacy reasons you can use this syntax : [key:parameter1,parameter2,parameter3…]

Snips

Easy snippet/Shortcode editor plugin for Wordpress

Brecht

Easily create a Facebook-like link preview for any link on your website. You can choose the image and text to display and create your very own custom template. The default template can be styled from the settings to match your website.
Some examples of what you could use this for:
<ul>
<li>A call to action for your affiliate links</li>
<li>Promote WooCommerce products on your website</li>
<li>List sources for your article</li>
<li>A weekly posty of interesting websites you’ve found</li>
<li>Link to related posts on your own website</li>
<li>…</li>
</ul>
It does not require any database lookups, which means even having many of these blocks on a page should not affect performance.
Compatible with both the Classic and Gutenberg Block Editor using shortcodes and blocks. Also includes full Elementor support with a dedicated widget for easy integration into your Elementor pages.
The plugin includes multiple URL metadata providers (PHP, Microlink API, and LinkPreview API) with automatic fallback switching. If one provider fails to fetch link information, the plugin automatically tries the next available provider. You can also manually retry with a different provider if needed.
