node.js instance manager

node.js instance manager is a simple application that lets you manage the execution of multiple instance of node.js applications. You can play/stop many instances and monitor them using a simple UI that reside in the system tray. You can specify the port of all instances and many other process parameters.

It is useful to have a single view on all your node instances that are running and being able to quickly restart them, etc.


main ui

  • You add a new node instance slot by pressing the Add button.
  • Then browse for a node.js startup script (same script you would start using node.exe on the command line).
  • If your node application is a server that needs a given port, enter it in the port field.
  • Finally press the Play button to start the node process. If it didn't crashed at startup, the icon should pass to a stop button state.
    • Pressing the stop button will kill the node process
  • Repeat the process for other node instances.

Improvements (TODO)

  • Port on Mac (partly done, just need to fix UI a bit)
  • Port on Linux
  • Start all nodes at once
  • Group nodes
    • Start all nodes of a group
  • Sort node instance slots (using a small drag and drop widget?)
  • Save logs
  • See in the log window stderr
  • Detect all started node.exe process and list them as new slots
