Debugging is an essential part of software development, and Laravel makes this process easier with its powerful tool — Laravel Debugbar. This package integrates a debugging toolbar directly into your application, allowing developers to inspect queries, routes, views, and much more in real time. Whether you are building APIs or web apps, Laravel Debugbar can significantly speed up troubleshooting and performance optimization.

In this blog, we’ll cover everything you need to know: Laravel Debugbar install, using it with APIs, managing it via Composer, and even how to disable it when not needed.

What is Laravel Debugbar?

Laravel Debugbar is a package developed by Barryvdh that integrates the PHP Debug Bar into your Laravel project. Once installed, it adds a sleek toolbar at the bottom of your application. This toolbar provides detailed insights into your application’s internals, including:

  • Database queries and execution time
  • Rendered Blade views and variables passed
  • Logged messages, warnings, and errors
  • Current route, controller, and middleware stack
  • Exception details for debugging

In short, Laravel Debugbar makes your development workflow smoother by giving instant visibility into what’s happening under the hood.

Laravel Debugbar Install

Installing Laravel Debugbar is straightforward. Since it’s primarily a development tool, you’ll want to install it only in your local environment. Open your terminal and run:

composer require barryvdh/laravel-debugbar --dev

The --dev flag ensures Debugbar is not included in production, keeping your app secure and optimized.

Once installed, Laravel automatically detects the package. If you’d like to customize its settings, publish the configuration file:

php artisan vendor:publish --provider="Barryvdh\Debugbar\ServiceProvider"

This creates a config/debugbar.php file where you can enable or disable specific panels, like queries, timeline, or exceptions.

Laravel Debugbar Composer Integration

Because Laravel Debugbar is managed through Composer, you can easily keep it updated or remove it if no longer needed. For example:

  • To update:
composer update barryvdh/laravel-debugbar
  • To remove:
composer remove barryvdh/laravel-debugbar

This seamless integration ensures Debugbar fits perfectly into your Laravel ecosystem.

Using Laravel Debugbar for API Development

One of the most common questions developers have is: Can I use Laravel Debugbar for APIs?

The answer is yes. While APIs don’t return HTML pages (and therefore don’t display the toolbar), Debugbar can still log requests and responses in the background. You can access the collected data through logs or integrate it with tools like Telescope or external API clients (e.g., Postman).

To make the most out of Laravel Debugbar for API projects:

  • Use \Debugbar::info($data) to log request and response payloads.
  • Track performance with the Timeline panel.
  • Debug queries and exceptions triggered by API endpoints.

This approach gives you the same insights as in web development, but tailored to API workflows.

Laravel Debugbar::disable – Controlling the Toolbar

Sometimes, you may want to disable Debugbar temporarily without uninstalling it. Laravel makes this simple with the laravel debugbar::disable method.

Example usage:

\Debugbar::disable();

This is useful when debugging sensitive routes, working with production-like environments, or when Debugbar slows down your development process. You can re-enable it anytime with:

\Debugbar::enable();

Additionally, you can permanently disable Debugbar by setting the following in config/debugbar.php:

'debug' => false,

Key Features That Make Laravel Debugbar Indispensable

  • Database Insights – View all executed queries, bindings, and execution time.
  • Performance Monitoring – The Timeline panel shows how long each part of your code takes.
  • Error Tracking – Catch exceptions and warnings instantly.
  • View Debugging – See which Blade templates are loaded and what data is passed to them.
  • Route Details – Quickly check controllers, methods, and middleware for the current request.

Best Practices When Using Laravel Debugbar

  1. Keep it local only – Never use Debugbar in production as it can expose sensitive information.
  2. Use it alongside Laravel Telescope – For an even deeper debugging experience.
  3. Leverage laravel debugbar::disable – Switch Debugbar off when profiling is not necessary.
  4. Optimize for APIs – Use Debugbar selectively to log data without cluttering API responses.

Final Thoughts

Laravel Debugbar is more than just a debugging tool — it’s a productivity booster for developers. From monitoring database queries to troubleshooting API responses, it gives you an inside look at your Laravel application with minimal setup.

To get started:

  • Run Laravel Debugbar install via Composer.
  • Use it smartly in web and API projects.
  • Disable it (laravel debugbar::disable) when not required.

With these practices, you’ll have a more transparent, efficient, and enjoyable development experience.
