FTB Modpacks Server Hosting Guide (2026)

FTB modpack server hosting

Feed The Beast (FTB) is one of the longest-running modpack platforms for Minecraft. Their packs range from tech-focused (FTB Infinity) to exploration (FTB Oceanblock) to kitchen-sink (FTB Revelation). Every pack is curated, tested, and designed to work together.

Popular FTB Modpacks in 2026

| Modpack | Type | Mods | Min RAM | |---------|------|------|---------| | FTB Infinity Evolved | Kitchen sink | 200+ | 6 GB | | FTB Revelation | Kitchen sink | 200+ | 6 GB | | FTB Oceanblock | Skyblock/Ocean | 150+ | 5 GB | | FTB Stoneblock 3 | Underground | 160+ | 5 GB | | FTB Direwolf20 | Tech/Exploration | 180+ | 6 GB | | FTB Presents Create | Create focused | 100+ | 4 GB |

Server Setup

Method 1: FTB Server Files

  1. Go to Feed The Beast
  2. Find your modpack and download the server files
  3. Upload the server files to your server
  4. Run the install script (./start.sh on Linux)
  5. Accept the EULA
  6. Start the server

Method 2: CurseForge

  1. Download the server pack from CurseForge
  2. Extract to your server directory
  3. Run the installer
  4. Start with the provided script

JVM Arguments

FTB modpacks are memory-hungry. Use Aikar's flags with extra allocation:

java -Xms6G -Xmx6G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:MaxTenuringThreshold=1 -jar forge-server.jar nogui

RAM Requirements

Heavy modpacks need more RAM than vanilla:

| Modpack Size | Player Count | Recommended RAM | |-------------|-------------|-----------------| | Light (50 to 100 mods) | 1 to 10 | 4 to 5 GB | | Medium (100 to 200 mods) | 1 to 10 | 6 to 8 GB | | Heavy (200+ mods) | 10 to 30 | 8 to 12 GB | | Heavy (200+ mods) | 30+ | 12 to 16 GB |

Common Issues

Server Crashes on Start

  • Check the crash log in crash-reports/
  • Usually a mod conflict or missing dependency
  • Verify Java version matches the pack requirements (Java 17 or 21)

TPS Drops

  • Use /forge tps to check performance
  • Limit chunk loading per player
  • Disable or reduce mob spawning with config tweaks
  • Restrict certain machines that cause lag (quarries, chunk loaders)

Client Cannot Connect

  • Client and server must run the exact same modpack version
  • Extra client mods (shaders, minimaps) are usually fine
  • Removing any mod from the pack breaks compatibility

Performance Tips

  • Pre-generate the world with Chunky before players join
  • Set view distance to 8 (FTB packs need less)
  • Limit the number of loaded entities
  • Restart the server every 12 to 24 hours to clear memory
