Shelly Cloud will shut down on March 31, 2016. All services you use will be operational until then. Read our announcement.
Please remember to turn off your cloud as soon as you finish migration (remember to remove your private IP endpoints too).
We don't want to charge you for redundant resources.

Rack-based Apps


Shelly Cloud supports rack compatible applications. It means that you can deploy applications written in frameworks such as sinatra or camping.


In order to deploy rack-based application to Shelly Cloud, the application must meet the following requirements:

  1. Configuration file must be present. It's common that rack-based frameworks generate this file. If you don't have it in your app's root directory, check your frameworks documentation.
  2. Minimal set of gems.
    source :rubygems
    gem "rack"
    gem "rake"
    gem "thin"
  3. File named Rakefile in your project's root directory with dummy db:migrate and db:setup tasks.
    namespace :db do
      task :migrate
      task :setup

Sample Rack-based Application

You can check out sample rack-based application on our github account. It's very minimal example and doesn't need database server.

Here is how deployment of this app looks like.

$ git clone git://
$ cd sample-rack-app
$ shelly add --code-name rack-123 --databases none
