# Asynchronous Handling and Scheduling

{% hint style="info" %}
Works with: **Laravel**, **Symfony**, and **Standalone PHP**
{% endhint %}

## The Problem

You added async processing, but now you can't tell which messages are stuck, which failed silently, and which will retry forever. Going async required touching every handler — adding queue configuration, serialization logic, and retry strategies individually.

## How Ecotone Solves It

Ecotone makes any handler async with a single `#[Asynchronous]` attribute. Retries, error handling, and dead letter are configured at the channel level And switch between synchronous and asynchronous execution without changing your business code.
