Another week and another feature that was on top of our most request features list is now complete: Support for other Rack servers like Unicorn, Thin and Puma.

By default, we serve your Rails application with Phusion
, but from today, if you would like to use Unicorn or any other Rack servers you can do that.

The process is as simple as putting a line in your Procfiles that is labeled as custom_web and following a couple of conventions to ensure traffic is redirected to your Rack server and Cloud 66 can control the process. Those are simple enough to integrate into your Unicorn configuration.

Please note: This feature is only available to new stacks.

You can find more detailed information about Unicorn support in Cloud 66.
