spatie/laravel-health
Monitor your Laravel app’s health by registering checks (disk space, etc.) with warning/fail thresholds. Get notified via mail or Slack when checks degrade, and extend with custom checks for proactive alerting.
The package contains a controller Spatie\Health\Http\Controllers\HealthCheckResultsController that can be used to render the latest results of all checks. Simply use that controller in your routes on any URL you desire.
use Spatie\Health\Http\Controllers\HealthCheckResultsController;
Route::get('health', HealthCheckResultsController::class);
Here's how that page will look like:

There is also a dark mode available:

You can enable dark mode by changing the theme key from light to dark in the config file.
If you don't want these results to be public, be sure to take care of authorization yourself.
If you want to run the checks in the same request, you can pass the fresh query parameter.
https://example.com/health?fresh
This way you'll see the fresh results in the browser.
