TwinDoors
by sev1ch
TwinDoors makes two wooden copper doors set in a pair, with their handles facing the opening, behave as one unit, so opening one opens the other.
What it does
When two wooden copper doors are placed next to each other with their handles facing the opening, TwinDoors pairs them and keeps them in sync. Opening or closing one door moves its partner at the same time. The mod works with doors that are operated by hand and does not need any redstone or extra blocks to link them.
TwinDoors is server-side only, so players join without installing anything and only the server runs it. It requires Fabric API, and files are published for Fabric alone across 12 game versions, released under the MIT License. The source code is public and the project is open source, with an issue tracker for reports.
Key features
Automatic pairing
Double doors placed handle to handle are detected and linked without any setup from the builder.
Synced opening and closing
Paired doors open and close together, so a double door never ends up half open after one side is used.
Wooden copper doors
The pairing applies to hand-operated wooden copper doors, which are the doors this mod targets.
Light on the server
The mod is described as lightweight, adding little load for server owners who run it.

Who it’s for: Builders and server owners who use wooden copper doors in double-door layouts and want the pair to open together.
How it compares
Geo's double doors is open source under the MIT License, with Fabric files for 1.21.1 – 1.21.5, and it runs on the client and server. 2 Doors is a server-side only Fabric mod for 1.21.11 that is not open source. Teleport Doors is a client and server Fabric mod for 1.21.11 released under CC0 1.0 Universal, so it is a different kind of door mod from TwinDoors. Synced Double Doors targets 26.1.2 – 26.3 on the client and server and is licensed as All rights reserved. Plaify is a client-side only Fabric mod for 1.21.4 – 1.21.5 under the MIT License that is not open source. TwinDoors covers only its own range on the server side.
