Installation

Install 3TSpawner on Paper or Purpur and activate your license.

Requirements

• Server software: Paper, Purpur, or Folia 1.20.6 through 26.x
• Java: Java 21 or newer
• Economy: Vault + an economy plugin (required for shop/sell)
• License: A paid 3TSpawner license key (product id 3TSPAWNER)
• Optional: PlaceholderAPI, WorldGuard, MythicMobs, EliteMobs, Stonkz

Folia uses the same region-safe scheduler facade as Paper/Purpur. After install, /3ts doctor should report Folia when running on a Folia host.

Install 3TSpawner

1. Stop your server.
2. Place 3TSpawner.jar in the plugins folder.
3. Install Vault and your economy plugin if they are not already present.
4. Start the server once so 3TSpawner generates its config files.
5. Stop the server again.
6. Open plugins/3TSpawner/config.yml.
7. Replace YOUR_KEY_HERE with your license key.
8. Start the server.

plugins/3TSpawner/config.yml

license_key: "MATT-XXXX-XXXX"
license:
  grace_hours: 72

Verification always runs on startup. grace_hours only helps if the license API is down and a previous successful verify for that key is still cached.

Claim your license

Join the support Discord and claim the 3TSPAWNER product license (for example /claim 3TSPAWNER). Paste the generated key into config.yml before running in production.

First checks

Run these after startup:

/3ts doctor
/3ts integrations
/3ts admin preset list

Recommended first preset on a fresh SMP:

/3ts admin preset apply casual-smp

If the plugin cannot verify the key and grace does not apply, it disables during startup. Check the console log and confirm the key is present, valid, and claimed for 3TSPAWNER.

Staging checklist

• Vault economy deposit/withdraw works
• Place / stack / break a physical spawner
• Open /3ts virtual, /3ts shop, /3ts storage
• Sell loot once (/3ts sell)
• Create a backup (/3ts backup create) before migration experiments
