About this Modpack
FabricBoost is a Fabric modpack designed to give you the best Minecraft experience by boosting performance without sacrificing amazing optional shaders and enhanced graphics. If you've ever dealt with lag or very choppy frames but still want high-quality visuals, FabricBoost is made for you. It includes a carefully chosen selection of performance mods that make your game run way smoother—even on lower-end systems—while still keeping the game looking great.
In addition to performance improvements, FabricBoost enhances your gameplay with quality-of-life mods. The built-in map mod gives you a clear, detailed view of your surroundings, making exploration easier and more fun. Plus, the zoom mod lets you get a closer look at distant places or mobs with a simple keypress, the experience immersive and keeping close to the base game.
Most of the mods in FabricBoost work on any server, but a few only work in your single-player world or on custom servers with those mods installed.
From smooth visuals to better navigation, FabricBoost makes Minecraft more enjoyable while keeping the core gameplay intact. If you want a modpack that boosts performance, improves visuals, and feels intuitive, FabricBoost is the perfect choice.

Frequently Asked Questions
FabricBoost 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 FabricBoost 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 €8/month).
Can I add custom mods to FabricBoost without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.4). 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.
FabricBoost 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.
