Let There Be Dark
by jacobxny
Let There Be Dark is a Fabric client mod that adds a dark mode toggle for Minecraft's interface and texture packs, switched without reloading resources.
What it does
Players switch between dark and light appearance with a toggle, and resource packs and texture packs pick up the change without a reload. Because the switch happens on the client, the mod can be added to any existing world or server setup.
Installation needs Cloth Config API and Fabric API, and Mod Menu is optional for opening its settings from the game menu. Builds exist for 1.21.4 – 1.21.8 and the latest file targets 1.21.8. The code is open source under the MIT License, and the source and issue tracker are public.

How it compares
ResBundler is a Fabric client-side mod for 1.21.10 – 1.21.11, released under the MIT License and open source, so it targets newer versions than this mod. Better Toggle Sneak is a Fabric client-side mod for 1.21.4 with all rights reserved and no open source code, so its license differs from this mod's MIT License. Repacked covers 1.21 – 1.21.7 under the GNU General Public License v3.0 only and is open source, so it overlaps this mod's range only on 1.21.4 – 1.21.7.
