You can run enyo apps in a webkit browser with mock services. Then just use the Chrome debugging tools.
Note that you'll have to start Chrome with the necessary command line switches to allow for file access or cross domain xhr.
If you need to debug against your app in the emulator or a device you can use the Ares debugger. https://ares.palm.com/AresDebug/
