Calagopus is a self-hosted, open-source Rust game server panel and Pterodactyl alternative. See features, licensing, and setup details.
Calagopus is an open-source, self-hosted panel for deploying and managing game servers such as Minecraft and Rust. It was written from scratch in Rust and React as a modern alternative to Pterodactyl Panel, a widely used PHP-based game server management tool, with the stated goals of better performance, a refreshed interface, and a more extensible plugin architecture.
The project has been publicly developed on GitHub since 2025 under the calagopus organization, with frequent point releases. It is free for personal and commercial use with no feature gating.
Each game server runs inside an isolated Docker container, and the panel supports Pterodactyl-compatible 'egg' presets so administrators can reuse existing game installation configurations. A Rust-trait-based plugin system lets developers extend both the frontend and backend.
The panel component runs on Windows, Linux, or Docker, while the Wings server-side daemon requires Linux; the project also supports ARM64 hardware, including Raspberry Pi.
Calagopus is entirely free and open source, with no paid tiers, subscriptions, or feature gating for personal or commercial deployments. Users are responsible for their own hosting infrastructure costs.
Yes. Calagopus is free and open source for both personal and commercial use, with no feature gating or paid tiers.
Yes. Calagopus must be self-hosted; the panel runs on Windows, Linux, or Docker, and the Wings server-side daemon requires a Linux host.
Calagopus is a from-scratch reimplementation of a Pterodactyl-style panel written in Rust and React rather than PHP, aiming for better performance and a more extensible plugin system, while remaining compatible with existing Pterodactyl egg presets.
Calagopus can manage Minecraft, Rust, and other Linux-containerized game servers supported through its egg system.
