DebugKit provides a debugging toolbar and enhanced debugging tools for CakePHP applications. It lets you quickly see configuration data, log messages, SQL queries, and timing data for your application.

⚠️ DebugKit is only intended for use in single-user local development environments. You should avoid using DebugKit in shared development environments, staging environments, or any environment where you need to keep configuration data and environment variables hidden. ⚠️


  • SQLite (pdo_sqlite) or another database driver that CakePHP can talk to. By default DebugKit will use SQLite, if you need to use a different database see the Database Configuration section in the documentation linked below.

For details and older versions see version map.


  • Install the plugin with Composer from your CakePHP Project's ROOT directory (where the composer.json file is located)
php composer.phar require --dev cakephp/debug_kit:"^5.0"
// src/Application.php
  • Set 'debug' => true, in config/app.php.

Is DebugKit not working?

If you don't see a CakePHP icon on the bottom right of your page DebugKit is not be working correctly. Some common problems are:

  1. Your PHP environment doesn't have SQLite installed. Check your application logs to confirm if this happening. You can either configure DebugKit to use a different database, or install the PDO SQLite 3 extension.
  2. Your hostname needs to be added to the DebugKit.safeTld. If your local domain isn't a known development environment name, DebugKit will disable itself to protect a potentially non-development environment.
  3. If you are using the Authorization Plugin you need to set DebugKit.ignoreAuthorization to true in your config.
