pm2 (GitHub: Unitech / pm2, License: MIT, npm: pm2) by Alexandre Strzelewicz is a command-line process manager for Node. It can be used to start a program as a cluster of processes, and then monitor the cluster's health, monitor the server itself (CPU/RAM/etc.), keep processes alive, log exceptions, and throttle programs that stop too quickly.

connectr (GitHub: olalonde / connectr, License: MIT, npm: connectr) by Olivier Lalonde is a wrapper for Connect that allows middleware to be inserted at arbitrary points in the stack. That means you can add middleware before existing middleware.
It has a simple API: the
