Kadira vs. AppDynamics vs. AppSignal

See what’s going on with your app with different performance metrics and traces. Kadira tracks all your client and server errors automatically. You can profile your app in production or locally with Kadira and analyze it using an easy-to-use CPU analyzer.

AppDynamics develops application performance management (APM) solutions that deliver problem resolution for highly distributed applications through transaction flow monitoring and deep diagnostics.

AppSignal gives you and your team alerts and detailed metrics about your Ruby application. We work with Rails, Sinatra and Grape and support Sidekiq, Delayed Job and Resque. Sensible pricing, no aggressive sales & support by developers.
