Cronicle is a multi-server task scheduler and runner, with a web based front-end UI. It handles both scheduled, repeating and on-demand jobs, targeting any number of slave servers, with real-time stats and live log viewer. It's basically a fancy Cron replacement written in Node.js. You can give it simple shell commands, or write Plugins in virtually any language. Please note that Cronicle currently only works on POSIX-compliant operating systems, which basically means Unix/Linux and OS X. If there is enough interest, I'll look into making it work on Windows.
