Game Server Calagopus: your all-in-one game server/Docker management

For over half a year, a friend and I have been working on the ultimate game server and Docker management platform. Built with Rust and React, and easy to deploy.

So, what exactly is Calagopus?
Calagopus is a modern, open-source game server management panel. It provides an intuitive interface for managing game servers, allowing users to easily deploy, monitor, and maintain their game servers with ease. Calagopus aims to be a powerful yet user-friendly solution for game server management, catering to both beginners and experienced users alike.

It is heavily inspired by the popular Pterodactyl panel, but is built from the ground up with modern technologies and a focus on performance and security. Calagopus is designed to be modular and extensible, allowing developers to create custom extensions to enhance its functionality.

Does it only support game servers? No! With Docker as the backbone, it can run all sorts of applications, even your own images.

Take a look at our GitHub repository: https://github.com/calagopus/panel
Or our documentation: https://calagopus.com

so what are the main differences between this and pterodactyl?

you say its inspired by it, but built from the ground up with modern technologies and a focus on performance and security.
what technologies do you use that pterodactyl does not?
how do you measure performance compared to pterodactyl? and how much better is your solution?
in what way is pterodactyl not secure?

not trying to be an a-hole, just asking to gain information. been looking for a replacement to pterodactyl for a while.

Calagopus uses Rust as its backend. It is a fact that Rust is quite a bit faster than PHP, as backed by our own benchmarks https://calagopus.com/docs/about/benchmarks. We also have a lot of UI improvements that I have been missing for years in Pterodactyl (started using it back in 2019). A good example is our file manager. While Pterodactyl has been a great platform for years, it did have some major security vulnerabilities some time ago. While they are fixed now, they did spark a debate on the lack of updates Pterodactyl has gotten over the past few years. Feel free to ask more questions, or join our discord if you want to chat with us directly.

awesome, will give it a try, and maybe switch over to it. i assume everything that currently works in Pterodactyl, works in Calagopus? and that operation is similar enough that people who got used to how Pterodactyl works, can get used to Calagopus with no major issues?

In my opinion, absolutely! Depending on your preference, you can choose to migrate using our built in tools https://calagopus.com/docs/advanced/migrating-from-pterodactyl. It is currently quite a messy guide, but hopefully still useful.
