YetAnotherConfigLib: Neat Config Library for Minecraft Fabric

YetAnotherConfigLib (YACL): A Fresh Take on Fabric Config Screens

If you run a Fabric modded instance and spend any time in options menus, you have probably bumped into “yet another” library name and wondered whether it really matters. YetAnotherConfigLib—YACL for short—does one thing on purpose: it helps mods build clean, Minecraft-styled configuration screens without turning into a giant toolkit of unrelated features.

That narrow focus is the whole point. On Fabric, blocks, biomes, crafting tweaks, and server rules all live in the same ecosystem, but the plumbing behind player-facing settings is easy to get wrong. A config library that looks pretty on paper can still feel cluttered in-game or stop evolving when maintainers move on. YACL was built with that hindsight baked in.

Why mod authors wanted something new

Fabric already had established names in this space, and each had tradeoffs that frustrated developers who mainly wanted “a good settings UI.” Cloth Config API, for example, has been widely used, but its trajectory has felt stagnant to some modders; the maintainer has indicated they likely will not keep expanding it in the way power users hope. SpruceUI can do UI work, but it is not purpose-built for configuration, which can make dense option lists harder to scan. OwoLib (and similar “does a lot” libraries like MidnightLib) bundles broader functionality alongside UI pieces, which can increase surface area and footprint when all you need is screens for tunables.

YACL positions itself as the specialist option: config screen generation first, nothing else pretending to be the core product.

What YACL does (and deliberately does not do)

YACL is intentionally lightweight. It is “just a config library” in the sense that it focuses on presenting settings in a way that fits Minecraft’s look and workflow. That also means it does not try to replace your whole configuration stack; managing serialization, file formats, migrations, and lifecycle decisions largely stays in your hands. That design choice keeps the dependency lean and avoids hidden opinions about how every mod should store data.

If you want a higher-level layer for AutoConfig-like ergonomics, the author points readers toward pairing YACL with Settxi rather than cramming that responsibility into YACL itself. In practice, that separation can be refreshing: screen code stays screen code, and your data layer stays where you want it.

Developer experience: APIs, styling, and documentation

From a modding mechanics perspective, the selling point is a straightforward API. YACL takes inspiration from Sodium’s internal configuration approach, which many Fabric players already associate with polished sliders and readable groups. The goal is not a flashy alien menu that fights the base game’s UI language, but something that feels like it belongs next to vanilla video and accessibility settings.

For implementation details, the project wiki is treated as the source of truth. If you are integrating across versions and updates, treat the wiki like you would patch notes for a biome update: read carefully, follow examples, and re-check when you bump Minecraft or Loader versions.

Players, packs, and practical setup

If you are a player rather than a coder, you may never “install YACL” as a headline feature. You will notice it most when a mod adds a tidy options screen instead of expecting you to hand-edit JSON. When you add or update Fabric mods after a Minecraft version bump, keep an eye on mod compatibility lists, because libraries like YACL often ride alongside the mods that depend on them.

Pack maintenance gets easier when your tooling is predictable; if you are juggling several dependency updates at once, swapping library versions can feel like reorganizing a storage room full of different block types—everything fits, but only if the labels match. If you like grabbing mods through a launcher that keeps the workflow in one place, this kind of library sits quietly behind the scenes while your loader handles the heavy lifting. Some players also streamline Fabric experiments by using the foxygame.net launcher—a flexible, modern Minecraft launcher that lets you pull mods directly from the menu, which can make iterative tweaking less of a scavenger hunt across sites.

License and ecosystem hygiene

YACL is released under the GNU Lesser General Public License, version 3. That matters if you fork, redistribute, or ship it inside a curated modpack, because compliance is part of keeping servers and communities on solid ground. Treat it like any other dependency: respect the license text, attribute appropriately, and verify you are distributing the version your mods actually require.

Conclusion

YetAnotherConfigLib is not trying to be the only library in your mod. It is trying to be the one that does config screens exceptionally well on Fabric—lightweight, styled to match the game, and shaped by lessons learned from older alternatives. Whether you are building worldgen toggles, performance tweaks, or server-friendly limits, a focused UI layer helps players understand mechanics without turning every update into a support ticket. Pair it with the right config-management helpers, follow the wiki as versions evolve, and you get a Fabric ecosystem that feels cohesive from the first launch to your hundredth crafting session.
