Disable Nether

A simple, lightweight plugin that lets you temporarily disable Nether portals on your server — no need to delete world files or restart your server.

Features

• 🔥 Blocks Nether portal teleportation for players and entities, even if the Nether world is already loaded
• ⚙️ Toggle on/off instantly with a single command — no restart required
• 💬 Customizable message shown to players when they try to enter a blocked portal
• 🪶 Lightweight — no dependencies, minimal performance impact

Why use this plugin?

Setting allow-nether=false in server.properties only prevents the Nether world from loading on startup. If the world_nether folder already exists and has been loaded before, portals will keep working regardless of that setting. This plugin fixes that by directly cancelling portal events, giving you reliable control over Nether access at any time.
