Simple Mod Pack to get started on my private server.
For others, this is intended for use on a vanilla-type server with no additional content. All the mods are client-side, and only interact with the server if the server also has the mods.
Most of the mods are quality of life, although if you're just joining someone's realm some of the tools provided here are likely overkill.

This pack Includes:
Multiple Performance Enhancing Mods (Sodium, Lithium, Phosphor)
Litematica for ease of construction and blueprinting
A Minimap and Worldmap Mod for tracking locations
Carpet and Carpet-Extras for extra information and higher-level debugging
Distant Horizons for insane render distance
Iris for loading shader packs
Freecam for screenshots and content-creation
Modmenu for improved setting management
and other QOL mods

These mods should barely affect your experience in survival at all, except for arguably the map mods.

If you would like, you can install these mods too:

Carpet-AutoCraftingTable

this mod works fine server-side, youd only need to install it if you plan on messing with autocrafting in singleplayer/creative worlds

ItemScroller

this is my clientside mass crafting mod. it also has features which overwrite mousewheelie, which seems to be a better mod for normal use

Litematica-Printer

this is the quick building mod i use in tandem with litematica. allows rapid building.

Remember to check for new releases when installing these!
