Usually too tight
The panel warns because many packs may fail to start or run poorly.
Search supported Modrinth packs from the panel, install the loader build the pack expects, and let the server select Java automatically. The tools reduce setup work, but pack compatibility and RAM still matter.
Find your pack in the panel, press install, and the server builds itself around it: the exact loader build the pack pins, its server overrides applied, and the client-only files it ships left out. Forge, NeoForge and Fabric packs, searched straight from Modrinth. No manifest reading, no loader archaeology, no jar juggling over SFTP.
Quilt-only packs and Forge packs below Minecraft 1.17 are not available. Compatibility is checked before anything on your server is changed.
Once you know which loader your pack uses, the loader guides go further: Fabric hosting covers dependencies and which mods can run on a server at all, and Forge and NeoForge hosting covers the version floors and why startup speed is not the thing to choose on.
If what you actually want is plugins rather than mods — permissions, land claims or moderation tools, with players joining on an unmodified client — Paper hosting is the better fit.
The manifest, the Minecraft version and the exact loader build — the three things people get wrong by hand.
If the pack cannot run here you find out while your server is still intact, not halfway through the install.
Pinned loader, server-side mods, the pack’s own config overrides. Not a mods folder full of hope.
The runtime the pack needs, chosen for you, and then it starts.
Installing a modpack replaces the current world, plugins, mods and settings. Mixing files from an unrelated setup into a pack creates hard-to-diagnose version conflicts, so the panel requires two confirmations before it starts.
Create a panel backup and download an off-server copy first. A backup is also essential before changing pack or Minecraft versions because worlds opened on newer versions may not safely downgrade.
Fabric, Forge and NeoForge sit in the same list as everything else, so moving your server between them is a dropdown rather than a rebuild.
Use these as starting points and follow the pack author’s requirement when it is higher. Large packs can need much more even with few players.

4 GB
A starting point to consider when the pack author’s requirements agree.
6 GB+
A better starting range for light modded play; large packs may require substantially more.
Use the RAM calculator for a starting point, then follow the pack author’s requirement when one is provided.

Treat 4 GB as a starting point only for lighter packs and 6 GB as a more practical starting point for light modded play. Large packs can need substantially more. Check the pack author’s requirements and tell support the exact pack before ordering.
Yes. A modpack install is deliberately a clean install: it replaces the current server files, world, plugins and settings. The panel requires confirmation and tells you to create and download a backup first.
You never pick one. The installer reads the Minecraft and loader versions the pack pins, installs that exact loader build and sets the Java to match — which removes the most common reason a modded server refuses to start.
Possibly, but the destination must match the Minecraft version, loader, loader build and mod set closely. Contact support with the exact pack or mod list before ordering so compatibility can be checked first.
Check the pack version and author guidance, choose enough RAM, and ask support to review an unusual or large pack before you order.
