Linkit

As of version 11.3, Drupal core provides link autocomplete suggestions in CKEditor similar to what this module does. Sites using or considering using Linkit should evaluate whether they can use the core solution instead of Linkit. Here is a list of features Linkit has that aren't currently included in Drupal core's version:

• Ability to configure which types of links will be shown in autocomplete suggestions, and how to group them
• Ability to create multiple Linkit "profiles" to be used on different text formats
• Linkit-styled autocomplete suggestions for link fields (core already has this, but it's entity suggestions don't have the configuration options below)
• Ability to configure metadata (with token support) for autcomplete suggestions; for example, showing the authoring information, published state for each suggestion
• Ability to configure the number of suggestions shown
• Ability to toggle published/unpublished entities in suggestions
• A Drupal form element for hyperlinks, allowing developers to use autocomplete functionality in custom Field Widgets
• An extendable plugin type for "Matchers," which determine what types of links can be suggested. Linkit includes a front page matcher, external link matcher, email address matcher, as well as matchers for user, taxonomy, media, and contact form entities.
• An extendable plugin type for "Substitutions" to customize what a match should render as
• For media entities, the ability to configure whether to link to the media entity URL or direct download
