FTB at a glance
| Type | a platform with many standalone packs, not a single modpack |
|---|---|
| Well-known packs | FTB Skies, FTB StoneBlock, FTB Direwolf20, FTB Infinity Evolved and more |
| Mod loader | Forge or NeoForge depending on the pack |
| Minecraft version | different per pack - stated in the FTB App and on feed-the-beast.com |
| Java | depends on the Minecraft version of the chosen pack |
| Source | FTB App or feed-the-beast.com; many packs are also on CurseForge |
| Own mods | FTB Chunks (claims and chunk loading), FTB Quests, FTB Teams |
| Recommended plan | depends on the pack - skyblock packs are more frugal, kitchen-sink packs memory-hungry |

FTB server hosting
Prepaid from €2.99 / month, unlimited slots, no minimum term. The right plan is listed in the RAM table below.
Plans & pricesThe installation route: FTB App or CurseForge
This is where FTB differs from practically all other packs on these pages. Most modpacks are on CurseForge, and our panel installs them from there with a click - loader version and dependencies included. Some FTB packs can be found there too; then exactly the same route applies as with ATM9.
For everything else, the FTB App or feed-the-beast.com is the source. There, you download the server files under the respective pack - an archive containing the complete server state. You upload this archive via SFTP or the web file manager into your server directory, set the matching loader in the panel and start.
That is one step more than the click installer, but no witchcraft - and it makes you independent of whether a pack has found its way into the installer. The general process is described in Install a modpack.
Which FTB pack suits which plan?
Because FTB is a whole family, there is no single answer to the RAM question. It makes more sense to classify by the type of pack:
- Skyblock packs such as FTB Skies generate hardly any terrain. They need little storage, run moderately in terms of memory - and, like SkyFactory, tend to stumble over leftover item entities.
- StoneBlock packs are played in a massive stone world. The world is small, but automation is intensive - the bottleneck is tick time.
- Kitchen-sink packs such as Direwolf20 behave like ATM: many dimensions, many chunks, high memory requirements. Here, plan L is the minimum and XL the safe choice.
The most reliable source remains the pack page itself: FTB states a recommended memory allocation for every pack. Take this number as the lower limit and plan one tier above it for several players.
FTB Chunks: claims that keep running offline
Almost every FTB pack brings FTB Chunks - and the mod shapes a server's load behaviour more than most others. Players use it to mark areas as their property (claims) and can keep part of them loaded permanently (force-loads) so that machines keep running after logging out.
That is practical and meant exactly that way. The side effect: force-loaded chunks tick around the clock. On a server where every player loads generously, the full base load is present permanently - even at night when nobody is online. If TPS on an FTB server slowly get worse over weeks without anyone building anything big, the sum of force-loads is almost always the explanation.
Sensible practice: agree on a limit within the team, release unused claims regularly and, when problems occur, check the loaded chunks first, not memory. How to measure this is described in Lag and TPS.
Which plan for FTB?
The thresholds below apply to this pack - a light Vanilla+ pack and a kitchen-sink pack with a hundred running machines behave completely differently. You can upgrade at any time without losing data and only pay the difference.
| Group | Plan | RAM | Price | Why | Order |
|---|---|---|---|---|---|
| Skyblock packs (e.g. Skies) | Plan M | 4 GB | €5.99 / month | Small world, moderate base load - 4 GB carry a small group. | Order M |
| StoneBlock packs | Plan L | 8 GB | €11.99 / month | Small world, but intensive automation over a long time. | Order L |
| Kitchen sink (e.g. Direwolf20) | Plan L | 8 GB | €11.99 / month | Minimum for small groups; plan one tier higher for several players. | Order L |
| Large groups, many force-loads | Plan XL | 16 GB | €21.99 / month | Permanently loaded chunks add up regardless of the number of players. | Order XL |
The memory is taken proportionally from the plan via -XX:MaxRAMPercentage - you don't need to maintain a fixed -Xmx. The basics are covered in the RAM guide.
Setting up FTB on the server
- Select the pack in the FTB App or on feed-the-beast.com and note its Minecraft version and loader.
- Check whether the pack is also on CurseForge - then installation works directly via the click installer in the panel.
- Otherwise, download the server files and upload the archive via SFTP or the web file manager into the server directory (stop the server beforehand).
- Set the matching loader in the panel: Forge or NeoForge, depending on the pack.
- Under Startup, choose the Java version matching the pack's Minecraft version.
- Start the server, wait for
Doneand agree within the team how generously force-loads are handed out via FTB Chunks.
Common pitfalls with FTB
The pack cannot be found in the installer
Cause: Not every FTB pack is distributed via CurseForge; some are only available via the FTB App.
Fix: Download the server files from feed-the-beast.com and upload them via SFTP. Then set the matching loader in the panel.
The server does not start after uploading
Cause: The archive was unpacked into a subfolder, or the loader set in the panel does not match the pack.
Fix: Check that mods/ and config/ are directly in the server directory, and align loader and Java version with the pack.
TPS get worse over weeks
Cause: The sum of areas force-loaded via FTB Chunks grows; they keep ticking offline.
Fix: Release unused claims and agree on a limit per player. The effect is usually measurable immediately.
Quests or claims reset after an update
Cause: FTB Quests and FTB Chunks store their data separately from the world; an update can change their format.
Fix: Before every update, back up the complete server directory, not just the world folder - see Create backups.
