Coalstack vs Crafty Controller

The short version

Of the tools on these pages, Crafty Controller is the closest to Coalstack in what it is for: both exist to run Minecraft servers, Java and Bedrock, for people who own the machine. The difference is the shape. Crafty is a web panel you run on a server and open in a browser. Coalstack is a desktop application, with an optional remote dashboard on top.

Crafty is free and open source, and that matters. If that is the deciding factor, it is a good answer.

Where Crafty Controller wins

• It is free and open source under the GPLv3, with nothing behind a paywall and source you can read and change.
• It runs in more places. Windows, Linux, macOS, Docker and UnRAID are all supported, while Coalstack is Windows and Linux.
• It is a web panel from the start. Anyone you give a login can manage a server from a browser on your network with nothing to install, and there is a mobile app for remote monitoring.
• It runs happily on a headless box. A server in a closet that nobody logs into is exactly what a web panel is for.

Where Coalstack is different

• It is built around the Minecraft problems people actually hit. An Auto Debugger reads a crash log and names the cause, a Modrinth marketplace installs mods and plugins, and mod compatibility checks flag likely conflicts before they crash a server. The Auto Debugger and the marketplace are on the free tier; the compatibility checks and the modpack installer are on Coalstack Plus. See the error code reference for what it catches.
• Getting reachable is part of the app. Port forwarding through your router, the firewall rule, a Playit tunnel, and dynamic DNS are tabs in the same window, rather than something you set up around the panel.
• Crossplay and networks are one tab each. Bedrock players can join a Paper, Purpur or Spigot server through Geyser, and a Velocity proxy can put several of your servers behind one address, both without editing config files by hand.
• Importing or resetting a world backs it up first, swaps it in, and rolls back if something goes wrong.
• Remote control without opening a port. Conduit has the app poll coalstack.net outbound, so no panel port is exposed on your router. The trade is that the relay runs through coalstack.net rather than a machine you own.

Which should you use?

Crafty Controller if you want free and open source, you are comfortable running a web service, you want macOS or Docker support, or the server lives on a headless machine you manage from a browser.

Coalstack if the server runs on a PC you sit at, you would rather have a desktop app than a panel to host, and crash diagnosis, mod installs and getting friends connected matter more to you than the licence.
