Stacker
by Andrew6rant
Stacker changes the maximum stack size of items, with the default set to 64 and a configurable limit that can go far above it.
What it does
Stacker lets server owners and players raise how many of each item fit in one slot. The default is 64, and the limit can be set in the mod config, though values far above 1 are not recommended. Support extends to stacks as large as 1,073,741,823. Stacker requires Fabric API and Cloth Config API on Fabric and Quilt, and Stacc API is embedded in the mod, so no separate file is needed. Client and server both need the mod, since only the client and the server running it agree on the stack sizes.
Key features

What the author says
This mod has a config that defaults to 64. Change it to be whatever you like (below int_max), but I do not recommend anything too far over 1 Billion (No support will be given for stacks larger than 1,073,741,823). Requires Stacc API and Cloth Config API. Stacc API is an embedded library, so don't worry about…
