How Laravel 11 Introduces a Built‑in Health Check Route (/up)

Laravel 11 adds a built‑in health‑check endpoint that can be accessed via the /up route.

The route is defined through the health‑check parameter in the new bootstrap/app.php configuration. By default Laravel configures it as follows:

Application::configure(basePath: dirname(__DIR__))
    ->withProviders()
    ->withRouting(
        web: __DIR__.'/../routes/web.php',
        // api: __DIR__.'/../routes/api.php',
        commands: __DIR__.'/../routes/console.php',
        // channels: __DIR__.'/../routes/channels.php',
        health: '/up',
    );

When the health route is registered, Laravel dispatches a DiagnosingHealth event. The default implementation returns a simple view that shows an animated “Application up” page.

use Illuminate\Foundation\Events\DiagnosingHealth;

if (is_string($health)) {
    Route::middleware('web')->get($health, function () {
        Event::dispatch(new DiagnosingHealth);
        return View::file(__DIR__.'/../resources/health-up.blade.php');
    });
}

The endpoint can be accessed at /up and will display the health page in the browser.
