AppSignal for Ruby

AppSignal supports the Ruby language with a Ruby gem. The gem supports many frameworks and gems out-of-the-box. Some gems and frameworks might require some custom instrumentation.

Table of Contents


The AppSignal Ruby gem integrates with many frameworks like Rails, Sinatra, Padrino, Grape, and more.

See our integrations page for the full list and implementation details.


It's possible to configure the AppSignal Ruby gem using an initializer, a configuration file or using environment variables. Read more about configuring AppSignal.


To make your own integrations with AppSignal or to add custom instrumentation to your application, see the instrumentation pages.

Ruby implementation support

Ruby (MRI)

We currently support Ruby 1.9.3+ for the latest gem version 1.x. To use this version add to your Gemfile.

gem 'appsignal'


At the moment please install the 0.11 version of the appsignal gem if you use jRuby. Add this line to your Gemfile:

gem 'appsignal', '~> 0.11.17'

We are working to support jRuby for the 1.x release, but cannot provide an ETA at this time.
