A Filament plugin that catches exceptions and emails them to your team, gives you a one-liner debug mail channel, and lets you browse log files from the admin panel -- no SSH required.

#Features

• Automatic error emails -- Stack traces, request context, and environment info delivered straight to your inbox when something breaks
• Configurable ignore list -- Skip exceptions you don't care about (like 404s and token mismatches)
• Per-exception throttling -- Same error won't flood your inbox; configurable cooldown period
• Recursive loop guard -- If the error email itself fails, it won't trigger more error emails
• Sensitive data scrubbing -- Passwords, tokens, API keys, and secrets are redacted automatically
• Debug mail via Facade -- FinSentinel::debug($data) sends whatever you're inspecting as a formatted email
• Fluent builder -- Chain ->subject(), ->to(), and ->send() for full control over debug emails
• Smart formatting -- Arrays, Eloquent models, collections, and query builders are formatted into readable HTML
• Event-based debug -- Fire SentinelDebug::dispatch($data) from anywhere, including queued jobs
• Log file browser -- List, search, and filter your Laravel log files from the admin panel
• File actions -- View, download, email, or delete log files without touching the server
• Memory-safe parsing -- Handles 100MB+ log files using indexed two-pass pagination
• Admin settings pages -- Configure both channels (error and debug) from the UI
• Shield integration -- Optional page-level permissions via Filament Shield
• AI error analysis (opt-in) -- Optional laravel/ai integration adds a provider-generated suggestion to the top of every error email, in the operator's locale

#AI Error Analysis

When laravel/ai is installed and the operator opts in, error emails carry a short suggestion section at the top of the body, generated by the provider you pick. The section is fully translated across 58 locales. The base package stays lean — laravel/ai is in suggest, not require, so v1.0 installs upgrade with zero behavior change until AI is explicitly enabled.

Configure provider, model, API key, prompt template, hourly cap, and cache TTL from the Error Channel settings page. The API key is stored encrypted at rest and injected into the SDK config per-call (never written to .env). A "Test" action button next to the API key validates the credentials with a one-shot SDK call without saving or sending an email.

#Provider compatibility

The AI feature uses laravel/ai, which supports nine text-capable providers: Anthropic, Azure OpenAI, DeepSeek, Gemini, Groq, Mistral, Ollama, OpenAI, and xAI.

Tested in production with:

• Anthropic

If you've successfully used another provider with FinSentinel, open an issue telling me which provider, model, and roughly what your traffic looks like — I'll add it to the list and credit you.

#Cost protection

A per-hour call cap and a three-strike circuit breaker (5-minute open window with half-open probe) sit between every error and the SDK call. Successful suggestions are cached by normalized exception fingerprint, so repeated occurrences of the same error reuse the previous answer for free. Token usage (last call + current month total) is shown on the settings page.

#Requirements

• PHP 8.2+
• Laravel 11+
• Filament 5

#Installation

composer require finity-labs/fin-sentinel

php artisan fin-sentinel:install

The install command will:

• Publish the config file and settings migrations
• Run migrations to create the settings tables
• Register the plugin in your selected Filament panel(s)

#Non-interactive install

Pass panel IDs as arguments to skip the interactive prompt:

php artisan fin-sentinel:install admin

In non-interactive mode (e.g., CI), the command registers the plugin in all discovered panels automatically.

#Register the plugin

If you skipped the automatic registration during install, add it to your panel provider manually:

use FinityLabs\FinSentinel\FinSentinelPlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        ->plugins([
            FinSentinelPlugin::make(),
        ]);
}

#Plugin options

FinSentinelPlugin::make()
    ->navigationGroup('Monitoring')      // string, UnitEnum, Closure, or null
    ->navigationSort(10)                 // ?int
    ->canAccess(fn () => auth()->user()?->is_admin)  // restrict access without Shield
    ->settingsCluster(MySettingsCluster::class)       // move settings to a custom cluster

The canAccess closure controls who can see all Sentinel pages. When omitted, every authenticated panel user has access. When Filament Shield is installed, its page-level permissions take priority.

The settingsCluster option lets you move the Error Channel and Debug Channel settings pages into a different cluster (e.g., a shared "Settings" cluster in your app). By default, they live in the built-in FinSentinelSettings cluster.

#Usage

#Error Notifications

Once installed, the error channel works automatically -- there's no code to write. When an exception or message is logged at error, critical, alert, or emergency level, FinSentinel catches it, formats the stack trace and request context, scrubs sensitive data, and emails it to your configured recipients. Lower-severity log events (debug, info, notice, warning) are always ignored -- use the debug channel for ad-hoc inspection instead.

To get started, open the Error Channel Settings page in your admin panel and:

1. Toggle the channel on
2. Add one or more recipient email addresses
3. Save

That's it. Errors will start arriving in your inbox.

You can also configure:

• Ignored exceptions -- Common exceptions like NotFoundHttpException and TokenMismatchException are ignored by default. Add or remove classes from the settings page.
• Throttle -- Enable per-exception throttling to avoid duplicate emails within a configurable time window.

To customize the error email template, publish the views:

php artisan vendor:publish --tag=fin-sentinel-views

#Debug Channel

The debug channel gives you a quick way to email yourself any variable, model, or collection for inspection. It's like dd() but it lands in your inbox instead of killing the request. Every FinSentinel::debug() call also writes a Log::debug() entry, so you always have a log trail regardless of whether the email is enabled.

#Using the Facade

use FinityLabs\FinSentinel\Facades\FinSentinel;

// Quick one-liner -- sends to the configured recipients
FinSentinel::debug($user);

// With a custom subject
FinSentinel::debug($order, 'Order inspection');

// Fluent builder for full control
FinSentinel::debug($cart)
    ->subject('Cart contents')
    ->to('dev@example.com')
    ->send();

When you call ->send(), the email goes out synchronously. If you don't call ->send(), the builder queues the email automatically when it's garbage collected -- so you won't accidentally forget to send it.

#Using the Event

If you prefer events (useful in queued jobs or when you don't want to import the Facade):

use FinityLabs\FinSentinel\Events\SentinelDebug;

SentinelDebug::dispatch($data, 'Optional subject');

The event listener always queues the email.

Note: The debug channel must be enabled in the admin settings before emails will be sent. The Facade and event both check the debug_enabled setting.

#Log Viewer

The log viewer lets you browse your Laravel log files from the admin panel. You'll find two pages under the Sentinel navigation group:

Log File List -- Shows all .log files in your storage/logs directory with file size and last modified date. From here you can:

• View -- Opens the log entry viewer with paginated entries
• Download -- Streams the file to your browser
• Email -- Sends the log file as an attachment to any address
• Delete -- Removes the file from disk (with confirmation)

Log Entry Viewer -- Displays individual log entries with:

• Level filtering -- Show only errors, warnings, or any combination of log levels
• Text search -- Filter entries by keyword
• Stack trace modal -- Click an entry to see the full stack trace with vendor frame detection
• Copy buttons -- Copy the message or full stack trace to your clipboard

The parser uses a two-pass approach (index first, then parse) so it can handle large log files without running out of memory.

#Settings

FinSentinel has two settings pages, both accessible from the admin panel:

• Error Channel Settings -- Toggle the error channel on/off, manage recipients, configure ignored exceptions, and set throttle rules.
• Debug Channel Settings -- Toggle the debug channel, set recipients, and configure throttle behavior.

#Configuration

Publish the config file:

php artisan vendor:publish --tag=fin-sentinel-config

The config file (config/fin-sentinel.php) contains:

Email layout -- Controls the max-width of error and debug notification emails. Stack traces and data tables benefit from extra space, so the default is wider than standard emails:

'email_max_width' => '90%',

The log file attachment email uses Laravel's default 600px width since it's a simple message.

Sensitive data scrubbing -- Values matching these keys are replaced with [REDACTED] in error and debug emails:

'scrub' => [
    'params'     => ['password', 'token', 'secret', '_token', 'credit_card', ...],
    'headers'    => ['authorization', 'cookie', 'x-api-key'],
    'env'        => ['DB_PASSWORD', 'APP_KEY', 'MAIL_PASSWORD', 'AWS_SECRET_ACCESS_KEY'],
    'trace_args' => ['password', 'secret', 'token'],
],

Each category targets a different data source. Keys are matched case-insensitively. Add your own keys to any category as needed.

#Customization

php artisan vendor:publish --tag=fin-sentinel-views
php artisan vendor:publish --tag=fin-sentinel-translations

#Filament Shield Integration

FinSentinel pages use the HasPageShieldSupport trait, which integrates with Filament Shield for page-level permissions. Shield is entirely optional -- without it, all pages are accessible to any authenticated user.

If you use Shield, generate the permissions:

php artisan shield:generate --panel=admin --option=policies_and_permissions

#Uninstalling

Run the uninstall command before removing the package:

php artisan fin-sentinel:uninstall
composer remove finity-labs/fin-sentinel

The uninstall command will:

• Remove FinSentinelPlugin::make() from your panel provider(s)
• Delete the published config file
• Optionally roll back settings migrations and clean up database entries

Use --force to skip confirmation prompts.
