## Overview

Incredibly easy way to perform **fire-and-forget**, **delayed** and **recurring jobs** in **.NET applications**. CPU and I/O intensive, long-running and short-running jobs are supported. No Windows Service / Task Scheduler required. Backed by Redis, SQL Server, SQL Azure and MSMQ.

Hangfire provides a unified programming model to handle background tasks in a **reliable way** and run them on shared hosting, dedicated hosting or in cloud. You can start with a simple setup and grow computational power for background jobs with time for these scenarios:

- mass notifications/newsletters
- batch import from xml, csv or json
- creation of archives
- firing off web hooks
- deleting users
- building different graphs
- image/video processing
- purging temporary files
- recurring automated reports
- database maintenance
- *…and so on*

Hangfire is a .NET alternative to [Resque](https://github.com/resque/resque), [Sidekiq](https://sidekiq.org), [delayed_job](https://github.com/collectiveidea/delayed_job), [Celery](https://www.celeryproject.org).
