.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.
💎 What Frost is
Frost is a performance-first Fabric client for Minecraft — the spiritual successor to FoxClient, rebuilt from scratch with a modern mod stack, a Vulkan renderer and zero unnecessary bloat. Tuned for CPvP and competitive play, preconfigured out of the box.

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. Lite unlocks inside the launcher once you sign in with the same Discord account. Details at frostclient.eu/lite.

🌋 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.

Frequently Asked Questions
FrostClient server crashes or won't start – what to do?
Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.
How much RAM does a FrostClient server really need?
Minimum 4 GB, recommended 6 GB for stable performance. per 8 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €5.2/month).
Can I add custom mods to FrostClient without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.2). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
FrostClient server lagging – performance tips
1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
