Browser Guard

A Laravel package that discourages:

• right click / context menu
• selected shortcut keys like F12, Ctrl+Shift+I, Ctrl+Shift+J, Ctrl+Shift+C, Ctrl+U
• casual DevTools opening through simple browser-side detection

Important note

This package does not provide real security. Anything running in the browser can be bypassed by a determined user. Use it only as a UI deterrent, not as a protection layer for sensitive data.

Installation

composer require dakshraman/laravel-browser-guard
php artisan browser-guard:install

Or publish manually:

php artisan vendor:publish --tag=browser-guard-config
php artisan vendor:publish --tag=browser-guard-assets

Add the script to your layout

In your main Blade layout, just before </body>:

@browserGuardScripts

Usage modes

1. Global mode

In config/browser-guard.php:

'mode' => 'global',

The script will load wherever @browserGuardScripts exists.

2. Middleware mode

In config/browser-guard.php:

'mode' => 'middleware',

Then apply the middleware only to routes you want to protect:

Route::middleware('browser.guard')->group(function () {
    Route::get('/protected-page', function () {
        return view('welcome');
    });
});

Useful config

'enabled' => true,
'block_right_click' => true,
'block_shortcuts' => true,
'detect_devtools' => true,
'show_alert' => true,
'alert_message' => 'This action is disabled on this page.',
'devtools_action' => 'alert', // alert | redirect | blank
'devtools_redirect_url' => '/',

Custom shortcuts

'shortcuts' => [
    ['key' => 'F12'],
    ['ctrl' => true, 'shift' => true, 'key' => 'I'],
    ['ctrl' => true, 'shift' => true, 'key' => 'J'],
    ['ctrl' => true, 'shift' => true, 'key' => 'C'],
    ['ctrl' => true, 'key' => 'U'],
],

Excluding paths

'except_paths' => [
    'admin/api/*',
    'health-check',
],

Suggested improvements

If you want this package to feel more production-ready, the next upgrades are:

• add tests with Orchestra Testbench
• add a facade or helper for runtime toggling
• add a small toast UI instead of alert()
• add IP/user-based exemptions
• add an inline-script fallback when published assets are missing
