Death Chests Mod
This modification solves one of the most annoying problems in Minecraft - losing all items when the character dies. When a player dies, two chests automatically appear at the death location, containing all the items from the inventory. Now you won't have to go searching for your valuable resources again!
One of the key advantages of this mod is its server-side implementation. This means it's sufficient to install the modification only on the server, and it will work for all connecting players, even if they don't have this mod on their client.
The mod works perfectly in single-player mode as well, providing protection for your belongings regardless of your chosen playstyle.

Pairs excellently with other useful survival modifications for Minecraft!
