CatQueue — Smarter Queueing & Seamless Pterodactyl Autoscaling for Velocity
CatQueue is a modern Velocity proxy plugin built to give players a smooth, frustration-free queueing experience while automatically scaling your Minecraft backend servers using Pterodactyl.

Unlike other queue plugins, CatQueue focuses on player clarity, admin safety, and long-term maintainability. It’s built with robust config migrations, live queue feedback, and first-class autoscaling — so your network feels professional and future-proof.

Why CatQueue?
Other queue plugins often…

• Spam chat with outdated queue messages.
• Break configs between updates, forcing manual rewrites.
• Ignore scaling, leaving you to manage server capacity by hand.

CatQueue solves these pain points by delivering:

• Continuous action bar updates (not just chat spam).
• Non-destructive config migrations (your comments stay safe).
• Automatic autoscaling with Pterodactyl (grow and shrink capacity based on demand).

It’s not just a queue — it’s a queue built for modern Minecraft networks.

✨ Features

• Continuous Action Bar Queue Status
  • Live queue position and ETA displayed right in the action bar.
  • Fully configurable format + update interval.
  • Cleaner, more professional than noisy chat spam.
    
• Pterodactyl Autoscaling Integration
  • Scale backend servers up/down automatically based on queue pressure.
  • Structured config for Pterodactyl API and application settings.
  • Keeps hosting costs down while maintaining great player experience.
    
• Safe Config Versioning + Migration
  • Every config includes a configVersion.
  • On startup, CatQueue generates a config.migrated.yml with new keys, leaving your original untouched.
  • You’ll never lose comments, formatting, or customizations.
    
• Clean, Extensible Config
  
  • Organized top-level blocks like pterodactyl and messages.
  • Easy to read, easy to extend.
  • Defaults automatically added during migrations.
