DelayedJob vs Sidekiq - quick comparison for your Rails app

Thinking about putting in DelayedJob or Sidekiq for your rails app? Here's a quick rundown of the pros and cons of each:

DelayedJob has been around the longest, created by the crew that built Shopify.com. It creates a table in your rails app and queues and works off of that. For me it provides the simplest option, as it carries no other dependencies other than your rails app.


  • no dependencies
  • simple
  • well supported


  • lives in your app, so constrained by app performance
  • no great user admin interface

Sidekiq offers a great alternative as well. It too is very simple and well-maintained, but instead of using your database, it uses a redis server to manage the jobs. That makes development a bit trickier, as you have to install redis and remember to start it when running your app. Not hard, just a bit extra stuff.


  • better performance possible
  • separate from app, so not dependent on app performance
  • great admin user interface


  • more complex to develop (need redis)
  • need a redis server to run app in production
