Write it once, run it everywhere. Events, networking, registries and configs, with screen effects, custom skies, cutscenes and GUI widgets on top: the purr-fect foundation for your mods.
Write it once, run it everywhere: the foundation for multi-loader mods, with the visuals to match.
One common codebase and a mod constructor
Listen to server, player, block and client events from common code, and send record payloads without writing a codec.
Deferred registers, creative tabs, menus with extra data and key mappings, all from common code.
Declare settings once with defaults, ranges and comments.
Typed data on players, entities, block entities and item stacks: saved with a codec, synced to who you pick, kept on death.
Custom skies, screen effects, world effects, cutscenes, text effects and GUI widgets, from common code.
Post-processing shaders you switch on, pulse or fade from code.
Layer gradients, cubemaps, sprites and shaders over the vanilla sky, from code or a resource pack.
Rainbow and gradient text, outlines and glowing borders for labels, buttons and titles.

✨ About
Write it once, run it everywhere. CoolCatLib is the purr-fect foundation for multi-loader mods: write your mod once in common code, and it runs on Fabric, NeoForge and Forge.
📦 Players: this is a library. It adds nothing by itself; install it when another mod asks for it.
🐾 One codebase, every loader
Set your mod up once, then register content, listen to events and send packets from common code. There are no per-loader classes to keep in step and no packet codecs to write: a record is the whole payload.
⚙️ Configs as code
Declare a setting once, with its default, range and comment. CoolCatLib takes care of the file, validation, live reloading, syncing server settings to players, and the commands to change them.
🎨 Visuals built in
Screen effects, custom skies, world effects and cutscenes, each a call or two away and controllable from the server, plus the widgets for polished screens.
