Exact Portals
by Mike
Exact Portals changes how Nether portals link, so a portal entered in one dimension lines up with the same x and z coordinates in the other.
What it does
Vanilla Minecraft scales coordinates by 1:8 between the Overworld and the Nether, which can place a return portal far from the spot a player left. Exact Portals removes that conversion and uses a 1:1 block coordinate system instead. When a player enters a portal, the mod searches the other dimension at the same x and z position, starting at the portal's y coordinate. It scans upward until it finds a portal, and then downward if none is found above.
If no portal exists at the matching position, the mod creates one at that exact position and size in the original dimension's counterpart. Each portal therefore links to one fixed x and z location, which the author describes as a perfect link system. The mod runs on the server only, so players join without installing anything, and it requires Fabric API. Files are published for Fabric alone, for 1.20.1, 1.20.2, 1.20.3, 1.20.4 and 26.2, with 1.2.1 for 26.2 as the latest file, under All rights reserved.
Key features
1:1 coordinate linking
Portals keep their horizontal position between dimensions, removing the 1:8 scaling of vanilla travel.
Upward and downward search
The search for a matching portal starts at the portal's y coordinate and checks upward first, then downward.
Automatic portal creation
When no portal is found at the target position, a new one is built at the exact position and size of the original.
Fixed link per position
Each x and z location links to one specific spot in the other dimension, with no ambiguity about the destination.

How it compares
NetherPortalHelper is a client-side only Fabric mod for 1.21.1 – 26.2 under the MIT License, so it adds nothing to a server. Instant Portal Nether is server-side only, under the MIT License, for 26.1.2 – 26.2. End Relay requires both client and server and is limited to 26.2, with the MIT License.

What the author says
This mod simply removes the "1:8 conversion" for the Nether, instead making it a 1:1 block coord system. This causes a lot of weird cases, as sometimes the portal spawns in less-than-ideal spots, otherwise it is awesome for linking up portals exactly.
