Suspenders Build Status Reviewed by Hound

Suspenders is the base Rails application used at thoughtbot.

Suspenders boy


First install the suspenders gem:

gem install suspenders

Then run:

suspenders projectname

This will create a Rails app in projectname using the latest version of Rails.

Associated services


To see the latest and greatest gems, look at Suspenders' Gemfile, which will be appended to the default generated projectname/Gemfile.

It includes application gems like:

And development gems like:

  • Dotenv for loading environment variables
  • Pry Rails for interactively exploring objects
  • ByeBug for interactively debugging behavior
  • Bullet for help to kill N+1 queries and unused eager loading
  • Bundler Audit for scanning the Gemfile for insecure dependencies based on published CVEs
  • Spring for fast Rails actions via pre-loading
  • Web Console for better debugging via in-browser IRB consoles.

And testing gems like:

Other goodies

Suspenders also comes with:


Read the documentation on deploying to Heroku

You can optionally create Heroku staging and production apps:

suspenders app --heroku true


  • Creates a staging and production Heroku app
  • Sets them as staging and production Git remotes
  • Configures staging with HONEYBADGER_ENV environment variable set to staging
  • Creates a Heroku Pipeline for review apps
  • Schedules automated backups for 10AM UTC for both staging and production

You can optionally specify alternate Heroku flags:

suspenders app \
  --heroku true \
  --heroku-flags "--region eu --addons sendgrid,ssl"

See all possible Heroku flags:

heroku help create


This will initialize a new git repository for your Rails app. You can bypass this with the --skip-git option:

suspenders app --skip-git true


You can optionally create a GitHub repository for the suspended Rails app. It requires that you have Hub on your system:

curl -sLo ~/bin/hub && chmod +x ~/bin/hub
suspenders app --github organization/project

This has the same effect as running:

hub create organization/project


Suspenders uses spring by default. It makes Rails applications load faster, but it might introduce confusing issues around stale code not being refreshed. If you think your application is running old code, run spring stop. And if you'd rather not use spring, add DISABLE_SPRING=1 to your login file.


Suspenders requires the latest version of Ruby.

Some gems included in Suspenders have native extensions. You should have GCC installed on your machine before generating an app with Suspenders.

Use OS X GCC Installer for Snow Leopard (OS X 10.6).

Use Command Line Tools for Xcode for Lion (OS X 10.7) or Mountain Lion (OS X 10.8).

We use Google Chromedriver for full-stack JavaScript integration testing. It requires Google Chrome or Chromium.

PostgreSQL needs to be installed and running for the db:create rake task.
