# Introduction

> Build faster, more reliable apps that make users happy

Cronatic is a task queueing service built for serverless and edge functions. It provides a simple, reliable, and scalable way to defer code execution, schedule background jobs, and build event-driven applications.

## How it Works

1. **Define:** Write your Task function in any language / framework.
2. **Enqueue (Schedule):** Tell us when the Task should run.
3. **Webhook:** We’ll notify you with a webhook when it’s time to execute the Task.
4. **Automatic Retries:** If something doesn’t work, we’ll try again.
5. **Task History:** Track what happened for easy debugging.
