Laravel Quota

Supports: Laravel 11, 12 & 13+ • PHP 8.2+ • Redis • Memcached • Database

Application-level quota management for Laravel. Track and enforce usage limits across daily, weekly, monthly, or custom time periods.

Manage quotas with a clean, expressive API using cache or persistent database storage, attach them directly to Eloquent models, protect routes with declarative middleware, and extend the package with custom storage backends.

Unlike Laravel's RateLimiter, which focuses on request throttling, Laravel Quota manages cumulative usage budgets over calendar periods such as daily, weekly, monthly, or custom windows.

Quick Example

Quota::for('monthly_exports', $user)
    ->limit(50)
    ->perMonth()
    ->consume();

echo Quota::for('monthly_exports', $user)
    ->remaining();

Common Use Cases

Laravel Quota is ideal for:

Monthly PDF export budgets
AI credits & prompt limits
API monthly request quotas
Tier-based billing restrictions
Team / workspace creation caps
File storage upload thresholds
Weekly newsletter dispatch budgets
Daily transaction volume limits

Why not RateLimiter?

Laravel's RateLimiter is excellent for protecting endpoints from bursts of traffic. Laravel Quota doesn't replace RateLimiter. Instead, it complements it by managing cumulative usage across longer calendar periods.

Laravel Quota focuses on application-level usage budgets with:

Monthly allocations
Daily limits
Team budgets
Usage metering
Calendar windows
Remaining capacity
Rich DTOs
Eloquent integration
Database persistence

Features

Expressive Fluent API: Chain expressive calls like Quota::for('pdf_exports', $user)->using('database')->limit(100)->perMonth()->consume().
Calendar Periods: Enforce quotas over exact calendar time periods (perMinute(), perHour(), perDay(), perWeek(), perMonth(), perYear(), or custom start/end windows).
Atomic Consumption: Prevent concurrent usage overages and race conditions using atomic execution (block()) or declarative route middleware.
Native Eloquent Integration: Attach the HasQuotas trait to any model for scoped action metering ($user->quota('pdf_exports')->limit(50)->perMonth()->consume()).
Route Middleware: Protect endpoints automatically using quota:action_name,limit,period with automatic HTTP 429 enforcement and Retry-After headers.
Multiple Storage Backends: Switch seamlessly between high-performance cache stores (Redis, Memcached, Array) and persistent database storage with automatic cleanup.
Immutable DTOs: Work safely with strict QuotaInfo Data Transfer Objects returning exact period boundaries (used, remaining, periodStart, periodEnd).
Custom Storage Backend Extensibility: Register custom storage backends on the fly with closure-based creators via Quota::extend().
Prunable Database Storage: Built-in Prunable trait integration ensures expired database records never clutter your database.

Installation

Ready to get started? Install the package with Composer:

composer require zaber-dev/laravel-quota

Publish the configuration and database migrations:

php artisan vendor:publish --provider="ZaberDev\Quota\QuotaServiceProvider"

Run migrations if you intend to use the database storage backend:

php artisan migrate

Configuration

The configuration file config/quotas.php allows you to define your default storage backend, backend parameters, and event dispatching behaviors:

return [
    /*
    |--------------------------------------------------------------------------
    | Default Quota Driver
    |--------------------------------------------------------------------------
    |
    | Supported drivers: "cache", "database"
    |
    */
    'default' => env('QUOTA_DRIVER', 'cache'),

    'drivers' => [
        'cache' => [
            'driver' => 'cache',
            'store' => env('QUOTA_CACHE_STORE', null),
            'prefix' => 'quotas:',
        ],
        'database' => [
            'driver' => 'database',
            'table' => 'quotas',
        ],
    ],

    'events' => [
        'dispatch' => true,
    ],
];

Usage Guide

1. The Fluent Quota API

The Quota facade provides an expressive builder interface for setting, checking, enforcing, and consuming quotas.

Setting & Consuming a Quota

use ZaberDev\Quota\Facades\Quota;

$builder = Quota::for('api_queries', $user)
    ->limit(1000)
    ->perDay(); // Available periods: perMinute(), perHour(), perDay(), perWeek(), perMonth(), perYear(), period($start, $end)

// Check current usage stats
$used = $builder->used();             // int (e.g. 240)
$remaining = $builder->remaining();   // int (e.g. 760)
$isExceeded = $builder->isExceeded(); // bool (false)
$hasCapacity = $builder->hasCapacity(10); // bool (true)

// Consume quota (throws QuotaExceededException with HTTP 429 if insufficient capacity)
$info = $builder->consume(5);

Enforcing Quotas (`enforce`)

If you want to automatically halt execution and throw an HTTP 429 Too Many Requests exception without consuming any units when the budget is exhausted, call enforce():

Quota::for('api_queries', $user)->limit(1000)->perDay()->enforce();

Atomic Block Execution (`block`)

For operations vulnerable to concurrent bursts or long-running tasks, use the block() helper. block() acquires a temporary atomic lock while the callback executes and only deducts quota units if execution completes successfully:

Quota::for('pdf_generation', $user)
    ->limit(50)
    ->perMonth()
    ->block(function () use ($pdfService, $user) {
        $pdfService->generate($user);
    }, amount: 1, lockSeconds: 30);

Resetting / Flushing Quotas

// Immediately reset the quota counter for the current period window
Quota::for('api_queries', $user)->reset();

// Flush all historical quota records for this action and target
Quota::for('api_queries', $user)->flush();

2. Eloquent Model Integration (`HasQuotas`)

Add the HasQuotas trait to any Eloquent model to scope quotas directly to that entity:

namespace App\Models;

use Illuminate\Foundation\Auth\User as Authenticatable;
use ZaberDev\Quota\HasQuotas;

class User extends Authenticatable
{
    use HasQuotas;
}

You can now interact directly with your model instance:

$user = User::find(1);

// Consume 1 PDF export quota from the user's monthly budget
$user->quota('pdf_exports')->limit(25)->perMonth()->consume();

// Check remaining budget
$remaining = $user->quota('pdf_exports')->limit(25)->perMonth()->remaining();

Polymorphic Database Querying

When using the database storage backend, HasQuotas also exposes a quotas() polymorphic relationship, allowing direct querying and bulk management:

// Get all database quota records assigned to this user
$activeQuotas = $user->quotas()->where('period_end', '>', now())->get();

// Delete all quota records for this user
$user->quotas()->delete();

3. Route Middleware

Protect routes declaratively without writing boilerplate checks in your controllers using the CheckQuota middleware:

use Illuminate\Support\Facades\Route;

// Enforce a monthly allowance of 50 exports per User / IP address
Route::post('/exports/generate', [ExportController::class, 'store'])
    ->middleware('quota:exports,50,month');

// Use a specific storage backend
Route::post('/api/v1/query', [ApiController::class, 'query'])
    ->middleware('quota:api_query,1000,day,database');

How the Middleware Works:

Before executing your controller, CheckQuota verifies remaining capacity (HTTP 429).
When your controller completes successfully (2xx or 3xx), the quota unit is consumed (consume(1)). If the controller fails due to validation (4xx) or server errors (5xx), no quota is deducted so the user can immediately correct their input and retry.

4. Working with Storage Backends (`using`)

By default, the package uses the storage backend defined in config/quotas.php. You can switch storage backends on the fly per request or action:

// Store high-frequency API checks in fast cache/Redis
Quota::for('api_ping', $ip)->using('cache')->limit(5000)->perDay()->consume();

// Store critical billing tier budgets in SQL database
Quota::for('monthly_exports', $user)->using('database')->limit(50)->perMonth()->consume();

Registering Custom Storage Backends

You can extend the QuotaManager with your own storage backends (e.g., DynamoDB, MongoDB) in your AppServiceProvider:

use ZaberDev\Quota\Contracts\QuotaDriverContract;
use ZaberDev\Quota\Facades\Quota;

public function boot(): void
{
    Quota::extend('dynamodb', function ($app) {
        return new MyDynamoDbQuotaDriver($app['config']['quotas.drivers.dynamodb']);
    });
}

5. Database Pruning (`Prunable`)

When using the database storage backend, expired records are automatically marked for pruning via Laravel's Prunable trait on the ZaberDev\Quota\Models\Quota model.

To clean up old records automatically, schedule Laravel's model:prune command in your console.php or Kernel.php:

use Illuminate\Support\Facades\Schedule;
use ZaberDev\Quota\Models\Quota;

Schedule::command('model:prune', ['--model' => Quota::class])->daily();

6. Events

Whenever a quota is consumed, exceeded, or reset, the package dispatches strongly typed events if enabled (quotas.events.dispatch = true):

ZaberDev\Quota\Events\QuotaConsumed: Dispatched when consume() deducts units ($key, $amount, $remaining, $info).
ZaberDev\Quota\Events\QuotaExceeded: Dispatched when capacity is exceeded ($key, $limit, $info).
ZaberDev\Quota\Events\QuotaReset: Dispatched when reset() clears a period window ($key, $info).

You can listen to these in your EventServiceProvider for logging, monitoring, or webhook triggers.
