A web-based parallel SSH console for managing multiple linux servers.

Do you have too many servers to manage manually, but not big enough for puppet/chef? Want an interactive feel while still deduplicating effort across 3-10 servers? Inspired by, this is a alternative with the following features:


  • Add servers by password or keypair authentication
  • Host the control server locally to avoid trusting a third party
  • Arrange servers into groups (e.g. all web servers, all database servers, ...)
  • Supports running commands in parallel
  • Response streams back in realtime over websockets
  • Run any #! script remotely (bash, php, node, python, ...)
  • Syntax highlighting text editor (thanks Codemirror!)
  • Includes some demo scripts demonstrating using multiple languages, realtime, and a longer script to update node.js binaries from


  • Install from npm (npm install opencommandio)
  • Configure servers.js as per inline documentation
  • Run the server (node ./core.js)
  • Browse to localhost:8081 and enjoy
  • Optional: Protect the server by nginx reverse proxy with http authentication, or similar

Check npm to see if there's a more recent version than from here.
