A plugin based control panel for Bukkit / Spigot http://dev.bukkit.org/bukkit-plugins/jpanel/
JPanel is a plugin based control panel for your minecraft server. It is viewable within a web browser, and does not require running any external web servers, or knowledge of PHP or databases. This plugin is in beta, and has a number of key features, including:
THIS PLUGIN REQUIRES JAVA 8. ALSO BE AWARE IT'S STILL IN BETA, AND THERE MIGHT BE BUGS OR INCOMPLETE FEATURES.
Since this plugin doesn't require anything else other than the Bukkit server, installation is extremely easy
As of JPanel Beta 5, you can now add pages to the panel. For more information, please see the guide.
All commands can only be executed through the console, either via JPanel or a standard minecraft console.
These are modified through the config file. Once modified, restart the server.
I'm developing a series of apps that you can use to access the panel. Currently, there is an app for windows 10.
All source code is avaliable on GitHub, check it out!
