PortalPeek
by spce_man
Players who travel through Nether portals can see the matching coordinates on a HUD overlay, so PortalPeek removes the need to convert positions by hand.
What it does
When a player stands near a Nether portal or moves between the Overworld and the Nether, PortalPeek shows the corresponding coordinates for the opposite dimension on screen. Converted Nether values are the Overworld values divided by 8, and converted Overworld values are the Nether values multiplied by 8. The overlay uses a semi-transparent background with drop shadows so the text stays readable over any texture.
PortalPeek runs on the client alone, so it works on a singleplayer world, a multiplayer server or a realm without any server-side install. Commands typed with a dot prefix, such as .portalpeek toggle, run locally and are never sent to server chat. The mod is released under the MIT License and is not open source. It is published for Fabric only, with builds covering 1.21 – 26.2 across 16 release versions.
Key features
Automatic coordinate conversion
The HUD displays converted Nether and Overworld coordinates without any manual math, updating as the player moves.
Proximity mode
When the proximity setting is enabled, the overlay appears only while the player stands within 5 blocks of a Nether portal, leaving the remainder of the screen uncluttered.
Quick-toggle hotkey
The H key, which can be rebound in the controls menu, switches the overlay on and off instantly.
In-game configuration
Scale, position and toggles can be adjusted in the settings screen, and ModMenu integration gives access to it.
Command support
Full slash and dot-prefix commands let players change settings from the chat line while the game is running.

Use cases
Who it’s for: Players who link Overworld and Nether portals often and want the corresponding coordinates without calculating them. Server owners need take no action, since nothing is installed on the server.
