Undespawnable
by otomir23
Undespawnable lengthens how long dropped items stay on the ground before they vanish, using enchantments and item data components.
What it does
Dropped items normally despawn after 5 minutes, a base value stored as 6000 ticks. Undespawnable changes that limit per item rather than only through the global game rules. A per-item data component sets the despawn time in ticks, and enchantments add extra time on top of the base value, so a stack can be made to last longer than the default.
The Persistence enchantments are the main way players extend item lifetime. Persistence II adds 5 minutes, bringing the total to 10 minutes under the default configuration, and Persistence III adds 10 minutes for 15 in total. A further level adds 15 minutes, reaching 20. Undespawnable overrides the game rules for these items, so the change applies even when the server rules are set to something else.
The mod requires Fabric API and Fabric Language Kotlin, and it is published for Fabric only, with one file for 1.21.4. Every player and the server need a copy of the mod. The code is open source under the MIT License.
Key features
Per-item despawn time
A data component on each item sets its despawn time in ticks, so different items can have different lifetimes.
Enchantment-based extension
Persistence enchantments add fixed amounts of time to the base despawn value, one step for each level.
Persistence levels
Persistence II adds 5 minutes, Persistence III adds 10 minutes and the highest level adds 15 minutes.
Game rule override
Despawn behavior for these items follows the mod's own settings instead of the server's global game rules.

Who it’s for: Server owners who want to change how long dropped items last, and players who use enchanted gear that should stay on the ground longer.
How it compares
I Died, My Xp Didn't is server-side only, open source under the MIT License and published for 1.21 – 1.21.1, so it does not need installing on clients. No Peaceful Despawn is server-side only, uses a custom license and is published only for 1.21.8, and it is not open source. DelTime is client-side only, open source under the MIT License and published for 1.21.8, so it does not run on a server.
