FrostClient
Frost Client is a clean, minimal performance modpack for 1.21.11 — the spiritual successor to FoxClient, rebuilt for modern Minecraft with more stability, more FPS, and zero bloat.
Quick answer
Which FrostClient release should I use?
Frost Client 1.21.11 - Vulkan is a complete pack release for 1.21.11 with Fabric 0.19.3. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 79 mods in this pack file.
Pack setup
How should I set up FrostClient for players and a server?
Use Frost Client 1.21.11 - Vulkan 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 FrostClient?
Frost Client 1.21.11 - Vulkan. Change the pack release and its contents or setup may change too.
The selected pack release is Frost Client 1.21.11 - Vulkan. That file is for Minecraft 1.21.11 with Fabric 0.19.3. It contains 79 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 FrostClient?

⚠️ This modpack is no longer updated
Frost has moved to its own launcher.
The .mrpack files on this page still work and you can keep playing them, but they are frozen. Every new Minecraft version, every new feature and every fix from now on ships only through the Frost Launcher.

➡️ Download the launcher at frostclient.eu/download
Why switch?
- 🆕 Newer Minecraft versions that will never come to this page.
- 🔄 One-click updates — no re-downloading a
.mrpackevery time something changes. - 🧊 The full Frost client: custom menus, HUD editor, built-in mods, friend list and capes.
- 🎛️ Instance management, mod browsing and settings transfer built in.
- ⚡ Frost Client Lite, if you want the tuned high-FPS build.
Your worlds, settings and resource packs are yours — the launcher can import an existing instance, so you do not have to start over.
🔑 Key Features
Performance & Rendering
- 🌋 A real Vulkan render pipeline alongside a standard OpenGL build — pick whichever runs best on your hardware.
- 🧵 Chunk loading, memory, networking and startup optimized together as one tuned pipeline, not a single "optimization mod".
- 👁️ Entity and foliage culling — stop spending frames on what you cannot see.
PvP & Combat
- 💀 Totem tracking and offhand warnings — never miss a totem pop again.
- 💣 TNT timers — know exactly when it is about to go off.
- 🎯 Hit feedback and a fully customizable crosshair.
- ⌨️ On-screen keystrokes for clips and POV footage.
Quality of Life
- 🎙️ Simple Voice Chat — built-in proximity voice chat, no third-party app needed.
- 👥 Built-in friend list — add friends and play together, no server to buy or host.
- 🧣 Custom capes, free, no third-party service.
- ⚙️ Every setting in one clean in-game menu, plus a drag-and-drop HUD editor.
- 🔭 Freelook, zoom, motion blur, custom skies and brightness controls that matter for PvP.
- 🎨 A custom branded main menu, not vanilla's.
- 🖼️ Bundled ready-to-go resource packs, including a custom Zipp CPvP pack, a lightweight "potato" pack and a dedicated PvP crosshair pack.

🌋 Crashing on the Vulkan build?
Vulkan performance depends heavily on your GPU and drivers. If you get crashes, missing rendering or startup issues, switch that instance to the OpenGL build — it needs no extra setup and runs on far more hardware. In the launcher you can keep both side by side and swap in a click.
🔗 Compatibility
- 🖥️ Minecraft versions on this page: 1.21 – 26.2 (frozen). Newer versions are launcher-only.
- 🧵 Mod loader: Fabric
- 🌋 Available as both Vulkan and OpenGL builds — Vulkan gives the bigger FPS boost, OpenGL runs on more hardware.
- ✅ Works with most CPvP and Optifine-format texture packs without issue.
