Webdebug brings browser-based dump debugging and breakpoints to Drupal 8 and Drupal 9, without relying on Xdebug or any other external tools.


  • Dump any type of variable to a browser tab, browser console, terminal, or file.
  • Explore complex objects without running out of memory.
  • Set breakpoints to halt execution and inspect your session, request, and response.
  • Inspect errors with a catch-all error page with full stack trace and source code viewer.
