NodeFly

It is an open source utility that will monitor for any changes in your source and automatically restart your server. It has a default support for node & coffeescript, but easy to run any executable (such as python, make, etc).

Determine in realtime what's happening inside your node process from the terminal. No need to instrument code to get the deets. Also splits stderr/stdout to help spot errors sooner.

Nodetime is an application performance management toolset in the cloud - an all-round solution for performance monitoring, optimization and troubleshooting.
