RPM Developer Mode

Be our guest. Try RPM Developer Mode for free on your local machine.

RPM Developer Mode is a free, lightweight Rails plug-in that lets you monitor your Rails app’s performance on your desktop. Use it for as long as you like. Take a Tour. When your app gets bigger, you can go beyond having a Rails monitor in Developer Mode. Take RPM with you to production with RPM Lite.

Try RPM Developer Mode

install dev mode

or, for those who prefer to copy/paste:

script/plugin install http://newrelic.rubyforge.org/svn/newrelic_rpm


Nice work! The New Relic agent is now installed.

Getting Started with RPM Developer Mode

  • Whenever you run your app in development, the New Relic Agent tracks the performance of every http request. It stores the last 100 http transactions in memory.
  • RPM presents this info as a collection of web pages within your application. To view performance information, including detailed SQL statement analysis, go to http://localhost:3000/newrelic and start drilling down.
  • Try it for free as long as you like on your desktop. There's no expiration date. Plug in to Developer Mode today.
  • We designed RPM Developer Mode to be an easy Rails application monitor. If you need help, check our Troubleshooting Guide & Documentation. You can post a message on our support site, or flip us and email: support@newrelic.com. Operators are standing by.
  • When you're ready to take your Rails app to production, don't forget to take RPM with you.
