Calagopus

The full write-up

Calagopus is an open-source control panel for deploying, monitoring, and maintaining game servers through a Rust and React interface. It suits everyone from a homelab owner to a hosting operator who wants to run the panel on their own infrastructure. The strongest case is a feature-complete, unrestricted free plan; the main planning issue is that game-server workloads still depend on a Linux Wings host and a shared kernel. Overview Calagopus combines server provisioning, monitoring, scheduled backups, role-based access controls, and a broad game-egg system in one self-hosted panel. Its supported catalogue covers Minecraft Java and Bedrock, Rust, ARK, Valheim, FiveM, and source-engine games, provided the game runs in a Linux Docker container. That makes it a practical foundation for mixed-game communities rather than a Minecraft-only dashboard. The self-hosted model gives operators control over deployment and data, but it also leaves upgrades, host security, and availability in their hands. Docker, binary, and package-manager installation paths accommodate different operating habits, while the web and API surfaces make it suitable for both manual administration and automation. Key features File work and recovery Server file editing goes beyond a basic browser file manager: collaborative editing, revision diffs, and restore tools support teams that change configuration together or need to recover from a bad edit. Scheduled backups add a second recovery layer, which is especially valuable for persistent worlds and communities with several administrators. Authentication and extensibility WebAuthn authentication accepts passkeys, biometrics, and hardware security keys. Those methods are a strong fit for operators protecting an administrative panel without relying solely on passwords. The Rust trait-based Extension API can add backend logic, routes, interface elements, and database migrations, so an operator or integrator can tailor the panel without being confined to built-in workflows. The API covers everything exposed in the panel UI, making external control and provisioning realistic rather than limited to a few administrative calls. Documented integrations for VS Code, Paymenter, WHMCS, Blesta, and FOSSBilling also give hosting businesses routes into development and billing systems. Container isolation Game servers run in isolated containers with dropped capabilities, seccomp, read-only root filesystems, and configurable resource limits. These controls reduce the blast radius of an individual game process and help operators enforce predictable resource use. They do not replace host hardening: containers share the host kernel, and a compromised host can expose every workload. Pricing Free — free. The plan is free for personal and commercial use and has no feature gating. There is no free trial because the complete product is already available at no cost. For a homelab, community server, or commercial operator comfortable managing infrastructure, this removes per-server licensing as a scaling concern. The trade-off is operational rather than financial: you provide the host, maintenance, backups, and support process yourself. Platforms Calagopus supports API, Linux, macOS, self-hosted, web, and Windows environments. The panel runs natively on Windows or through Docker Desktop, but Wings—the component that runs game servers—requires Linux. A Windows administrator can therefore manage the interface from Windows while still needing Linux capacity for actual game-server workloads. That distinction matters when selecting a node provider or designing a home setup. Who it's for Choose Calagopus if you run several supported games, need team administration, or want to connect panel actions to billing and development tools. Its unrestricted plan and extension system also suit hosting operators building a customized service. It is less suitable when you require game workloads to run directly on Windows, need protection against a compromised host, or prefer a vendor-managed service instead of maintaining your own panel and nodes. Pros and cons Pros No feature gate or licensing cost: the free plan covers personal and commercial use. Broad container-based game support: Minecraft, Rust, ARK, Valheim, FiveM, and source-engine servers fit one panel. Serious administrative tooling: collaborative edits, diffs, restores, backups, roles, and WebAuthn address real team-operations needs. Deep integration surface: a full UI-level API and Rust extensions can support custom workflows and commercial integrations. Cons Linux is mandatory for Wings: Windows can host the panel, not the game-server runtime. Shared-kernel risk remains: container isolation does not defend workloads from a compromised host. Pterodactyl Blueprint extensions do not carry over: they target Pterodactyl's PHP architecture and cannot be reused in Calagopus. Self-hosting is an operational commitment: infrastructure, updates, and support are yours to run, with help directed to the Discord community or [email protected]. Alternatives Browse Game server control panels for a wider comparison. Crafty Controller is another free, open-source option with broad platform coverage, including Android and iOS. Pick Multicraft if you want a freemium model with a personal-use free tier and paid per-gameserver scaling. Zomboid Control Panel is the more focused choice for a self-hosted, MIT-licensed setup. GameAP offers another free, open-source self-hosted panel. GameCP fits operators who want a 14-day community tier with one node and three game servers, plus paid upgrades. HaruHost is an alternative freemium hosting tool. Teploy Arcade is a free, open-source deployment and operations tool. Kretase provides a free-forever, MIT-licensed, self-hosted option. Verdict Calagopus is a strong recommendation for self-hosters and hosting operators who need one extensible panel for multiple Docker-based games, with team controls and no feature-gated plan. Choose it for its breadth, API, and security-conscious container controls; look elsewhere if Linux Wings cannot fit your deployment or if you need isolation that survives a compromised host.
