How does the free RPM Developer Mode plug-in work?
The free plug-in is, of course, free. You can use RPM Developer Mode on your local machine for as long as you like. Upgrade anytime when your app is production-ready by simply clicking the Upgrade link on your Developer Mode home page, or by visiting this page. RPM Lite is free to run in production for as long as you like. Unplugging RPM is easy, too. If you don’t like it, you can unplug in seconds, without a trace.
