Ping Overlay

See every player's latency right on their nametag.

Ping Overlay is a lightweight client-side Fabric mod for Minecraft 1.21.11 that appends each player's ping in milliseconds to their nametag, with clear color coding so you can read connection quality at a glance.

Features

• Client-side only (no server install required)
• Shows ping as [Xms] next to player nametags
• Color-coded quality display:
  • Green: low ping
  • Yellow: medium ping
  • Red: high ping
• In-game settings screen from the pause menu
• User-editable config file support
• Cached ping updates (3-second refresh interval) for low overhead
• Keeps vanilla nametag behavior and visibility rules

In-Game Configuration

You can change ping thresholds without editing source code:

• Open the pause menu (Esc) and click Ping Overlay Settings
• Set:
  • Green max ms
  • Yellow max ms
• Save and continue playing

If you prefer manual config, edit:

config/ping-overlay.json

How Colors Work

• Green if ping is less than or equal to greenMaxMs
• Yellow if ping is above greenMaxMs and less than or equal to yellowMaxMs
• Red if ping is above yellowMaxMs

Example: if you want red to start at 120+, set yellowMaxMs to 119.

Performance

Ping values are cached and refreshed every 3 seconds per player, reducing repeated lookup work while keeping values current.

Compatibility

• Minecraft: 1.21.11
• Mod Loader: Fabric
• Environment: Client

Why Use This Mod?

• Quickly spot laggy players in PvP or co-op
• Easy to tune thresholds for your server or region
• Minimal impact and clean vanilla-style integration

Notes

• Ping display is only available when ping data is provided by the client network player list (typical multiplayer behavior)
• Singleplayer/integrated worlds do not represent real network latency the same way as remote servers
