CullTag
CullTag hides player nametags that sit behind solid blocks, so a player cannot spot another player through a wall by their name alone.
What it does
CullTag works on the server. It runs a raycast from each viewer's eyes to the nametag position, and when a solid block sits between them the nametag is not sent. Glass, panes, bars, chains and ladders do not hide a nametag, and a datapack tag named culltag:transparent lets server owners add more blocks that never hide one. Named mobs and armour stands follow the same rule, while hologram stands without a visible block in front of them stay readable.
Because the calculation and packet interception both happen on the server, players connect with an unmodified vanilla client and need nothing installed. Fabric API is required. The mod is server-side only, released under the MIT License and open source, with files for 26.1 – 26.2. Its configuration can be toggled and reloaded live, and changes persist to the config file without a server restart. Built-in profiling reports how the system performs.
Key features
Server-side nametag culling
Nametags behind solid blocks are removed from the packets sent to each viewer, so they stay hidden on the client.
Transparent block list
A datapack tag lets server owners mark more blocks as transparent, and changes apply without a server restart.
Named mobs and armour stands
Named mobs and armour stands are culled by the same raycast as player nametags, while open hologram stands stay visible.
In-game management
Commands turn the culling system on and off, reload it and change its settings, provided the player has the matching permission.
Built-in profiling
Performance metrics show how much work the raycasting costs while the server runs.

How it compares
Hide Names is a Fabric client-side only mod under the Creative Commons Attribution Non Commercial 4.0 license, not open source, for 1.18.2 – 26.1.2, so each player installs it. No Player Nametags is server required with client optional, released under the MIT License, not open source, for 26.2 – 26.3. Show Player Nametags is client-side only and open source under the MIT License, covering 1.21.2 – 1.21.11, so only the client changes.

What the author says
Vanilla Minecraft gives every player a free, built-in wallhack: nametags visible through solid blocks. CullTag fixes this unfair advantage with highly optimized, server-side raycasting. If a player is hiding behind a wall, their nametag is gone. It’s that simple.
