This plugin is ultra lightweight. It adds a media button above the tinyMCE editor on both the page and post editor, which when pressed copies a shortlink to your clipboard.
The idea behind this plugin is to add short-linking capabilities, without all the bloated code found in other plugins. This plugin does not alter the database, nor is any data saved or collected. It uses the built in WordPresspost/page ID’s in the URL.

ERP ShortLinks

A very lightweight plugin which adds a shortlink button to the post/page editor for quickly sharing on social platforms.

kURL connects your WordPress site to your self-hosted YOURLS installation.
The name kURL combines kurz URL — “short URL” in German — with the familiar term URL. In other words, kURL is built for creating and managing short URLs from WordPress.
It lets you create short URLs for posts, pages, and supported custom post types directly from the WordPress admin area. You can generate links manually, create them automatically when content is published, assign custom keywords, refresh click statistics, and process older content in bulk.
kURL also includes migration tools for older Better YOURLS data, local logging for troubleshooting, and optional helper code for true remote deletion and safe reverse lookup on the YOURLS side.
Requires a self-hosted YOURLS installation with API access. No third-party shortening service is included.
If your server uses Nginx instead of Apache, add a deny rule for the <code>wp-content/uploads/kurl/</code> directory in your Nginx configuration to protect the log folder.
