Description

title

✨ Frost is a performance-first Fabric modpack for Minecraft — the spiritual successor to FoxClient, rebuilt from scratch with a modern mod stack, a Vulkan renderer, and zero unnecessary bloat. 72 handpicked mods, tuned for CPvP and competitive play, all preconfigured out of the box.

🌋 Having crashes on the Vulkan build?

  • Vulkan support depends heavily on your GPU and drivers. If you experience crashes, missing rendering, or startup issues, visit our Vulkan support page: https://frostclient.eu/vulkan

💎 What to Expect

  • ⚡ A real Vulkan renderer (VulkanMod + Beryl) alongside a standard OpenGL build — pick whichever runs best on your hardware.
  • 🧊 A deep, purpose-built performance stack under the hood — not just "one optimization mod," but a whole tuned pipeline.
  • 🥊 Built around CPvP: tier tags, totem tracking, TNT timers, and hit feedback baked in from the start.
  • 🆕 Native support for 1.21.11, maintained going forward.

want-more

Frost Client Lite pushes performance even further — on average 100–400 more FPS than classic Frost, depending on your hardware. Subscribers also get an in-game badge, a special Discord role, priority tickets, and staff pings. Check it out at frostclient.eu/lite.

🔑 Key Features

Performance & Rendering

  • 🌋 VulkanMod + Beryl — a modern Vulkan render pipeline with frame smoothing on top of it.
  • 🧵 C2ME, Krypton, FerriteCore, Noisium, ModernFix, VMP, BadOptimizations — chunk loading, memory, networking, and startup all optimized together, not in isolation.
  • 👁️ EntityCulling & CullLeaves — stop spending frames on what you can't see.
  • 🖥️ ServerCore — faster singleplayer worlds and integrated servers.

PvP & Combat

  • 🏷️ TierTagger — see a player's PvP tier right next to their name.
  • 💀 Totem Offhand Warning + Totem Highlight — never miss a totem pop again.
  • 💣 TNT Timer — know exactly when it's about to go off.
  • 🎯 HitColorPlus & Crosshair Addons — clean hit feedback and a fully customizable crosshair.
  • ⌨️ Key Overlay — on-screen keystrokes for clips and POV footage.

Quality of Life

  • 🎙️ Simple Voice Chat — built-in proximity voice chat, no third-party app needed.
  • 📦 Chest Tracker & Shulker Box Tooltip — see what's inside without opening it.
  • ⚙️ Mod Menu + YACL / Cloth Config — every mod's settings in one clean menu, in-game.
  • 🖱️ Smooth Scroll & Multi Key Bindings — the small stuff that adds up.

Customization & Visuals

  • 👥 Built-in friend list — add friends and play together, no server to buy or host.
  • 🧣 Better Capes / Wavey Capes — free custom capes, no third-party service.
  • 🔭 Freelook, Zoomify, toggleable Motion Blur, Skyboxify, Gamma Utils — camera and visual tweaks that matter for PvP.
  • 🎨 A custom branded main menu (ImproperUI), not vanilla's.
  • 🖼️ Comes bundled with a few ready-to-go resource packs, including a custom Zipp CPvP pack, a lightweight "potato" pack, and a dedicated PvP crosshair pack.

  1. ⬇️ Install the Modrinth App if you don't already have it.
  2. 📦 Download Frost from this page — pick the Vulkan or OpenGL build for your Minecraft version.
  3. 🖱️ Open the downloaded .mrpack file — the Modrinth App picks it up and installs everything automatically.
  4. ▶️ Launch Frost as an instance from the Modrinth App and play.

Don't own Minecraft? The official Modrinth App needs a premium (Microsoft) account. For an offline/cracked account, use AstralRinth instead — a fork of the Modrinth App with offline account support — and follow the same steps above.

🔗 Compatibility

  • 🖥️ Minecraft version: 1.21 - 26.2
  • 🧵 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.
