Validate Links As-You-Type

Check for valid hyperlinks inside the editor

Contribute to this page

The Link Checker plugin provides a link checking service right within the TinyMCE editor.

Think of Link Checker as "spell checking for links". But instead of checking spelling, it will let you know if a link in the editor is valid, invalid or questionable. This is a huge time-saver for anyone who creates content — no more having to double-check URLs, especially in imported content. Not to mention the benefit of no longer frustrating readers with broken links.

Link Checker is available as a stand-alone plugin or as part of our Pro Bundle. To learn more about your options, check out our pricing and plans here.

Your have two deployment options. One is super easy with TinyMCE Cloud, the other is to go the more traditional SDK route, requiring an additional server-side component to be installed and configured.

Link Checker Cloud Quick Setup

TinyMCE Cloud makes setting up Link Checker a breeze. Simply include the linkchecker parameter in your tinymce.init and have our Cloud services do the work for you.

Link Checker SDK Quick Setup

If you'd rather deploy Link Checker via SDK, you have a little more work to do. Once you've got the server-side component installed, additional configuration to your application.conf file is required. (Don't forget to restart the Java application server after updating the configuration.)

This element configures the Link Checker service's built-in cache. When a hyperlink is checked and confirmed valid, the result is cached to save unnecessary network traffic in the future.

Default settings are automatically configured, meaning these settings are optional.


ephox {
  link-checking.cache {
    capacity = 500
    timeToLiveInSeconds = 86400
    timeToIdleInSeconds = 3600

There is also more SDK setup information on the Link Checker plugin page.

Important note: The Link Checker server currently does not support integration with IBM WebSphere Application Server.
