PortalEvent
by Galaxio82
PortalEvent gives server administrators scheduled and event-driven control over Nether and End portals, with countdown warnings for players before each change.
What it does
Portals on the server can open on a set schedule, at random times, or when a special event fires because of conditions the server meets. Each opening or closing is announced to players in advance, with messages sent five minutes and one minute before the change, so people inside or near a portal have time to prepare.
When a portal closes, any players still inside are moved safely back to the Overworld, which keeps them from losing progress or being stranded in another dimension. The mod is server-side only: players join without installing anything, and only the server needs the mod. It is released under the MIT License and is open source, with its source code and issue tracker public. Files exist for NeoForge alone, and the only game version supported is 1.21.8.
Key features
Scheduled portal openings
Administrators can set portals to open at fixed times so players can plan trips to the Nether or End.
Random and event-based openings
Portals can also open at random times or when a server condition triggers a special event.
Countdown alerts
Players receive messages five minutes and one minute before a portal opens or closes.
Safe return on closing
Players still inside a closing portal are teleported back to the Overworld, so they are not left in another dimension.

Use cases
Timed portal events on a server
A server can open Nether or End portals at set hours, giving the community shared windows for dimension travel.
Surprise openings
Random or conditional openings can make portal access less predictable for players on a long-running world.
Who it’s for: Server owners who want to control when players can use Nether and End portals, and who want players warned before each change. The mod only needs to run on the server.
How it compares
Simple Server Restart is a Fabric server mod for 1.21.5 – 1.21.11 that is open source under the MIT License, so it covers restarts rather than portals. LFT: 1 season is a NeoForge mod for 1.21.1 that is server-side only in the sense that players need nothing extra, and it is released under All rights reserved. Vanilla+ Disable Portals is a Fabric mod for 1.21.5, server-side only, under All rights reserved, and it disables portals instead of scheduling them.
