Portal Anchor
by v3rg1l
Portal Anchor keeps mobs that travel through Nether portals from despawning before they can reach a nearby player on the other side.
What it does
Mobs that pass through a portal arrive in a dimension where players may be far away. In vanilla, a mob in that short grace window after dimension travel is removed at once when the nearest player is out of range. This breaks portal-based farms, particularly ones that shuttle creatures between the Overworld and the Nether, because the mobs vanish on arrival. The mod keeps those mobs alive long enough to reach a player, which fixes a narrow but disruptive server problem.
The mod runs server-side only, so players join without installing it. It also works in singleplayer, where the same despawn behavior applies. The author built it for technical survival servers that run portal farms. Server staff can adjust the mod's behavior from inside the game, and the mod is open source under the MIT License. Files are published for Fabric, and the latest file is 1.0.1-26.1.2 for 26.1.2, released on 2026-05-24.
Key features
Grace window for portal mobs
Mobs that come through a portal keep existing past the vanilla despawn check while they wait to reach a player.

Use cases
Portal farms on survival servers
Mob farms that route creatures between dimensions keep their output when the mobs arrive far from any player.
Who it’s for: Server owners who run technical survival servers with portal farms, and players who build such farms in singleplayer. Players who only join a server do not need to do anything.
How it compares
Let There Be Portal Farms! is server-side only, open source under the MIT License, and targets 26.2 – 26.3, so it does not cover 26.1.2. Portalfarm Fix is server-side only, open source under the MIT License, and covers 26.1.2 – 26.2. PortalNuhUh is server-side only for 26.1.2 under a custom license and is not open source.

What the author says
Portal Anchor fixes a niche but painful vanilla server issue: mobs can disappear after going through a Nether portal if they arrive in a dimension where players exist, but are very far away. That can break portal-based farms, especially setups that move mobs between the Overworld and the Nether.
