Using Laravel Telescope For Debugging

Laravel Telescope is an open-source debugging tool by Laravel. It is open-source, free and available on Github. You can install it by adding it as a Composer dependency.

What is Laravel Telescope?

Telescope is a debugging tool which is a combination of different watchers for incoming requests on your application such as HTTP Request, Command-Line Requests, Scheduler or Queue.

These watchers catch-all type of information about these requests like database queries, query execution time, events fired and much more.

Installing Laravel Telescope

Before installing the Telescope, you need to have Laravel installed. If you want to create a new application you can run below command in your terminal and it will create a new Laravel project.

composer create-project laravel/laravel Telescope

To install Telescope, run below command:

composer require laravel/telescope --dev

You can use --dev tag to install it as a dev dependency or you can install it without this tag.

After the installation is set and done, you can move to prepare the assets, config files, and database by running:

php artisan telescope:install
php artisan migrate

Configuring Laravel Telescope

Right after the installation, you can open the route /telescope and you will be presented with Telescope like below:

You can change the route in the config/telescope.php file. This file allows you to configure Laravel Telescope. Most important options are:


This is the path within your application which will allow you to access telescope. The default value is telescope.


This is where Telescope will store the data. The default value is database.


This will determine which database connection to use. It’ll use your default database connection.


This will determine how much data Telescope will store for everything you will debug. The default value is 100.

Restricting Access to Telescope

In your local environment, any user can access the Telescope. Let’s say in the production environment you want to restrict the access for selected users. To achieve this, go to app/Providers/TelescopeServiceProvider.php file and find the gate function.

 * Register the Telescope gate.
 * This gate determines who can access Telescope in non-local environments.
 * @return void
protected function gate()
    Gate::define('viewTelescope', function ($user) {
        return in_array($user->email, [

You can add a list of emails. Users with this email will have access to Telescope.

Features of Telescope

The telescope comes with multiple options, where you can monitor the processing of almost everything. I mostly use the below tabs to look after the performance of my application.


This tab contains information about all incoming HTTP requests to your application.

The command-tab shows all the executed commands as well as their exit code. You can as well see arguments, options and related items for those commands.
