Coolite
by kazut0
Coolite is a Fabric client-side HUD that draws the cooldowns of Hoplite's items as an overlay on the screen while a player plays.
What it does
Coolite shows active item cooldowns on the HUD, with a progress bar and the remaining time for each item. Its position and scale can be set anywhere on the screen, and the layout can grow to the right or to the left. Custom Model Data support lets the HUD display the correct custom item texture that a pack assigned.
The mod is written for Minecraft 1.21.x on Fabric Loader and needs Fabric API. Mod Menu is optional and gives in-game access to its settings. Only the player's client needs the mod, so it is a client-side only addition. Its author also designed it for servers that use custom cooldown systems through the Apollo protocol.
Coolite is published for Fabric only, with a single build for 1.21.11. The code is not open source; it is released under All rights reserved.

Use cases
Hoplite item tracking
Players of Hoplite-style item setups can watch several cooldowns at once instead of tracking timers by hand.
Custom cooldown servers
Server owners who run custom cooldown systems over the Apollo protocol can give players a readable overlay for them.
Who it’s for: Players who use items with cooldowns on a Fabric 1.21.11 client, and server owners whose cooldown systems use the Apollo protocol.
How it compares
Cooldown Hud is another Fabric client-side cooldown display for 1.21.11, but it is released under All rights reserved and is not open source. Chronos Timer is also client-side only for 1.21.11 and is open source under the MIT License, so its code can be read and reused. MovableInventory is client-side only on Fabric for 1.21.8 – 1.21.11 and is a different kind of mod, moving the inventory layout rather than showing cooldowns.
