Item tool
by RethinkQAQ
Item tool is a Fabric client-side mod that shows data about item entities in the world, such as velocity, stack count, age and pickup delay.
What it does
Item tool reads the NBT tag data of item entities and displays it on screen. The readout covers velocity on the x, y and z axes, horizontal speed split into its x and z components, and the stack count of each item stack. It also indicates whether an item entity is touching the ground, and shows its age measured as time since it spawned.
The mod further displays the remaining lifespan of an item entity, since vanilla item entities despawn after 6000 game ticks, along with its pickup delay and portal cooldown. Because parsing an item entity's data requires operator permission level 2 or higher, the mod is most useful to players with operator rights on a world or server. Files are published for Fabric only, for game versions 1.20 – 1.21.10, and the code is licensed under the GNU Lesser General Public License v3.0 only, so it is open source.

Use cases
Inspecting dropped items
Players can check how far a dropped stack has traveled and how close it is to despawning, without leaving the game world.
Debugging item behavior
Anyone studying how item entities move, fall or pass through portals can read their exact values as they change.
Who it’s for: Players and map makers who want to inspect item entities during play, particularly those with operator permission level 2 or higher. The mod only runs on the client, so it is installed on the player's side.

Since it works by parsing the item entity's data, you need to have permission level 2 or higher to use it. This is my first attempt at developing a relatively complete…
