Xenith
a Fabric‑based modpack built for players who love the vanilla feel. It enhances performance, fixes long‑standing bugs, and adds lightweight quality‑of‑life improvements.
Quick answer
Which Xenith release matches Quilt?
MC Xtended 1.21.4-1 is a complete pack release for 1.21.4 with Fabric, Quilt. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 52 mods in this pack file.
Pack setup
How should I set up Xenith for players and a server?
Use MC Xtended 1.21.4-1 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.
A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.
These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.
What are the server requirements for Xenith?
MC Xtended 1.21.4-1 on Quilt. The pack contents and setup notes below stay tied to that release.
The selected pack release is MC Xtended 1.21.4-1. That file is for Minecraft 1.21.4 with Fabric, Quilt. It contains 52 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.
About this project
What kind of pack is Xenith?

Xenith
Xenith is a Fabric modpack that preserves the vanilla Minecraft experience, while improving performance, fixing many bugs, and adding quality of life features.
It’s aimed at players who want a modernized vanilla experience — featuring better performance, smoother rendering, fewer stutters, and small UX improvements, all while maintaining the vanilla charm.
Highlights:
- Performance first: modern Fabric optimizations for both client and server.
- Vanilla parity: bugfixes and QoL that do not alter core mechanics.
- One‑click server creation: open your singleplayer world to friends with one click using e4mc — it makes your LAN world public so friends can join easily. It also supports offline mode: disable online mode when opening to LAN if you need to play without online authentication.
- Cosmetics: get a cape at MinecraftCapes and show it in‑game using the included cape support mod.
- Optional server package: download a ready‑to‑use
Xenith_Server.zipcontaining a fabricserver.jar, an optimizedstart.sh, and all server‑side mods for quick deployment. Download it from GitHub.
- Core optimizations spotlight:
- Sodium — massive FPS gains through rendering optimizations.
- Lithium — faster tick calculations and mob AI improvements.
- FerriteCore — reduced memory usage for chunk and block data.
- ImmediatelyFast — snappier responsiveness and reduced stutter.
- ScalableLux — optimized light engine for better performance.
- Smarter resource use: mods like Clumps, Dynamic FPS, and Entity Culling reduce idle resource usage, merge XP orbs, and skip rendering hidden entities — keeping gameplay smooth even on lower‑end systems.
- Improved network stack: Krypton optimizes server networking for lower latency and smoother multiplayer performance.
- Beginner‑friendly tools: mods like Jade, Xaero’s Minimap & World Map, REI, and Enchantment Descriptions make the game easier to learn by showing block info, guiding exploration, simplifying recipes, and explaining enchantments — perfect for new or inexperienced players.
- Bugfixes included: long‑standing vanilla issues are patched with mods like Debugify and ModernFix, ensuring smoother gameplay.
- Flexible visuals: built‑in shader support with Iris and curated packs like Complementary Reimagined or Vanilla Plus Shader let you enhance graphics without breaking vanilla style.
- Lightweight customization: UI polish from BetterF3, Raised, Reese’s Sodium Options, and Ping View makes menus cleaner and more informative without overwhelming players.
