Latest Stable Version License


Keep your Neos website free of broken links with this easy-to-use link checker

CodeQ.LinkChecker makes sure all your links are working smoothly in Neos projects. It validates internal page and asset references, external links and phone numbers in node data, as well crawls all rendered pages to ensure that no hidden pages fall through the cracks!

Backend Module screenshot

The backend module allows you to mark errors as fixed and as to-be-ignored. Editing buttons directly open relevant pages in the Neos inline editing to easily fix the issues.

The link checker has the following methods to find broken links:

  • The backend module can validate all internal page links node://XXX and assets asset://XXX in all node properties
    • Additionally, it validates phone numbers to be in international format (+99 999999999)
  • The command controller ./flow checklinks:crawl will crawl all in the settings configured domains and pages and check the following:
    • Do all internal links node://XXX point to visible pages (not hidden, not hidden via visible before or visible after)
    • Are all phone numbers in international format (+99 999999999)
    • Do external links point to valid pages (http status code 2xx)
  • The command controller ./flow checklinks:crawlnodes will only validate internal links, assets and phone numbers
  • The command controller ./flow checklinks:crawlexternallinks will crawl the website and validate external links


CodeQ.LinkChecker is available via packagist run composer require codeq/linkchecker. We use semantic versioning so every breaking change will increase the major-version number.


Configure the link checker sync in your settings, like this:

    # how many concurrent requests should the command controller perform
    # If set too high, you will DDoS your server
    concurrency: 10

Make sure the domains are also added in the "Sites Management"!

Setup a cronjob e.g. daily to execute ./flow checklinks:crawl

Email reports

The link checker can also send an email report with a csv attachment with a list of all broken links. To enable this, you need to configure the email service like this:

      enabled: true
      subject: 'Link checker results'
      minimumStatusCode: 300
            name: 'Link Checker'
            address: ''
            name: 'John Doe'
            address: ''

Limitations and possible future Features:

  • Support additional languages
  • Use a job queue for crawling
  • Update the link checks after a page is published via a job queue
  • Check external links against malware oder security adviser lists
  • Find all occurrences of external links to internal pages
  • Check against deny list (e.g. list of competitors)
  • Check for broken links in other workspaces
