Better Config
by Meldexun
Better Config is a Forge library for 1.12.2 that replaces the annotation-based config system with its own annotation, BetterConfig.
What it does
Developers annotate a config class with BetterConfig instead of Forge's Config annotation, and the mod processes that class in its place. Config values can then be edited in the game through a GUI instead of only by hand in a text file. The mod extends Forge's built-in configuration mechanism, so the existing config setup still applies.
Better Config is published for Forge 1.12.2 only, with the latest file 1.12.2-1.3.0 dated 2026-09-23. Client and server both need it, so the mod must be installed on both sides. The code is open source under the MIT License.
Key features
BetterConfig annotation
A config class is marked with BetterConfig in place of Forge's Config annotation to be processed by the mod.
In-game config editing
Values declared through the mod can be changed from a GUI in the game, not only by editing files.
Built on Forge's config mechanism
The GUI and annotation work extend Forge's underlying config mechanism, keeping the same storage behind it.

What the author says
To then migrate from Forge to BetterConfig, you only have to - annotate your config class with @BetterConfig instead of @Config and - replace all invocations of ConfigManager.sync(String, Type) with BetterConfigManager.sync(String). That's it! Now your config will be processed by BetterConfig.
