Displacer
by Kaonicping
Displacer is a Fabric technology mod that adds an in-between block for moving items, which sits between a vacuum hopper and a hopper duct in how it behaves.
What it does
Displacer takes items out of the world and its surroundings and moves them along, acting as a hybrid between a vacuum hopper and a hopper duct. Its suck and push rates are set by the mod, and when it pulls items it works through a stack at a time, with a limit of one stack in its inventory. Redstone controls the block: a low signal leaves it idle, while a high signal makes it try to pull items from the world, and the result depends on the signal in the previous game tick.
Both Fabric API and Fabric Language Scala are needed alongside the mod. Displacer provides a comparator output, which lets players read its state with a comparator, though a slower transport line may be needed to catch the signal. Files are published for Fabric only, for game versions 1.16.2, 1.16.3 and 1.16.4, and the environment is client and server, so the server and every player need it. The license is a custom one and the mod is not open source, though its source code and issue tracker are public.
Key features
Hybrid item intake
The block combines the pulling of a vacuum hopper with the transfer behavior of a hopper duct, so it can both collect and move items.
Redstone-driven behavior
Its actions switch on a high or low redstone signal, and the result also depends on the signal state in the previous tick.
Comparator output
A comparator can read the block's output, with a signal strength of 0 when it is idle.
Single-stack inventory
The block holds one stack at a time, with suck and push timing set by the mod rather than by hopper speed.

How it compares
Vacuum Hopper is a Fabric mod for 1.19.2 – 1.19.4 that shares the client and server environment with Displacer, under a custom license and not open source. EasyAutoCrafting is a Fabric mod for 1.16 – 1.21.8 that is server-side only and open source under the MIT License, so players can join without installing it. Super Hopper and Slow Hopper cover Fabric, Forge, NeoForge and Quilt, while Displacer is limited to Fabric.

What the author says
The Displacer provides a comparator output as you would expect. You will probably need to slow down its transport until you get the comparator signal since otherwise it will be too fast for the comparator to catch.
