Calagopus vs AMP
AMP (Application Management Panel) by CubeCoders is a commercial, closed-source game server management solution with deep integrations for specific games. Calagopus is free, open-source, and built in Rust. This page covers the key differences to help you decide which fits your use case.
Quick Summary
| Calagopus | AMP | |
|---|---|---|
| Language | Rust | C# (.NET) |
| License | MIT (open source) | Commercial (closed source) |
| Price | Free | Paid (per-instance licensing) |
| Extension System | Native (Rust traits) | None publicly documented |
| Game-specific Features | Community eggs | Deep built-in integrations |
| Windows Panel Support | ✅ | ✅ |
| ARM64 Support | ✅ | ✅ |
The Core Tradeoff: Open Source vs Commercial
The most fundamental difference between Calagopus and AMP is the licensing model.
Calagopus is MIT-licensed and free for any use - personal, commercial, or otherwise - with no feature gating, no instance caps, and no licensing cost at any scale. You can inspect, modify, and contribute to the source code on GitHub.
AMP is proprietary software sold under a commercial license. Pricing is per-instance; running many game servers or many nodes increases cost. You cannot inspect or modify the source code.
For self-hosters and budget-conscious hosting providers, this is often the decisive factor. For operators who prioritize vendor support and specific game-level integrations, AMP's commercial model may be a reasonable trade-off.

Where Each Panel Leads
AMP's Advantage: Deep Game Integrations
AMP's primary differentiator is game-specific feature depth. For games like Minecraft, AMP ships integrations that surface game-native data - online players, in-game events, world management tools - directly in the panel UI without relying on a generic console approach. For hosting providers whose entire business is one or two specific games, AMP's native integrations can be genuinely useful.
Calagopus takes a more generalist approach. The egg system supports any Linux-containerizable game, and community eggs handle configuration for hundreds of games. What you don't get is the same level of game-native UI integration. If you need to serve game-specific configuration dialogs for specific titles, AMP has the lead.
Where Calagopus Leads: Open Source and Extensibility
Extension system. Calagopus ships a native Rust extension API. Extensions can add backend logic, custom routes, database migrations, UI elements, CLI commands, event handlers, and more. Because extension points are defined in the Rust type system, integrations are stable and type-checked. AMP has no public extension system.
No licensing cost at any scale. Calagopus has no per-instance, per-node, or per-user pricing. Whether you're running a three-server homelab or a multi-node commercial operation, the cost is zero.
File management depth. Calagopus adds file edit history, archive browsing, and backup browsing - features AMP doesn't offer in the file manager. Being able to browse inside a .zip or a backup snapshot without extracting it first saves meaningful time during server maintenance.
Shell access. Calagopus gives users direct SSH shell access to their server container from the web UI. AMP provides console access but not a full interactive shell.
Database type flexibility. Calagopus supports MySQL/MariaDB, PostgreSQL, and MongoDB as server-managed database types. AMP supports none of these as game database hosts.
User impersonation. Calagopus lets admins impersonate any user - useful for support workflows and debugging permission configurations. AMP does not have this feature.
Egg ecosystem. Calagopus ships with a built-in egg repository browser. Hundreds of community-maintained eggs are available for Minecraft variants (Java, Bedrock, Paper, Fabric, Forge, Velocity, BungeeCord), Rust, ARK: Survival Evolved, Valheim, FiveM/RedM, CS2, Garry's Mod, 7 Days to Die, Factorio, Terraria, and many more. The egg format is also compatible with the wider Pterodactyl/Pelican ecosystem.
Dynamic backup configuration. Calagopus's backup system lets administrators define multiple named backup targets (different S3 buckets, different retention policies) and assign servers to specific targets. This is useful for tiered storage or compliance requirements. AMP uses a single backup configuration.
Who Should Use What
Choose Calagopus if:
- You want a free, open-source solution with no licensing cost
- You're self-hosting or running a multi-game hosting operation
- You want an extension system to add custom functionality
- You value transparency and community contributions
- You need database-host functionality with PostgreSQL or MongoDB
- You're migrating from Pterodactyl or Pelican and want to keep your egg library
AMP may be worth evaluating if:
- Your operation is heavily focused on a specific game that AMP integrates natively
- You have budget for commercial software and prioritize vendor support
- You prefer a closed-source solution
Frequently Asked Questions
Is Calagopus really free for commercial use?
Yes. The MIT license permits commercial use without restriction and without licensing fees.
Can I use Calagopus for a game hosting business?
Yes. There are no per-node, per-server, or per-user restrictions. You can run Calagopus on as many hosts as you need. Integrations with billing systems like Paymenter, WHMCS, and Blesta are available.
Does Calagopus support Minecraft?
Yes. Calagopus supports Minecraft Java Edition, Bedrock Edition, Paper, Fabric, Forge, NeoForge, Velocity, BungeeCord, and other Minecraft-adjacent software via community eggs. See the egg repositories guide for how to add egg repos to your panel.
Can I migrate from AMP to Calagopus?
There is no automated migration path from AMP to Calagopus - the data models are different. You would need to set up Calagopus fresh and recreate server configurations. This is typically a manageable process for small installations. The installation guide is the starting point.
Does Calagopus have a commercial support option?
Calagopus is community-supported. The Discord server is active, and issues can be filed on GitHub. If you need guaranteed SLAs or dedicated support contracts, AMP or a managed hosting solution may be a better fit.
