No Automated Mod Manager
Palworld doesn't have a Mods-tab browser on this platform — there's no catalog to search and no one-click install like Satisfactory or Rust get. Anything beyond the base server has to be handled manually, and a manual mod setup for Palworld isn't a verified, tested process here.
How Palworld Modding Actually Works
The Palworld mod scene is built around UE4SS (Unreal Engine Scripting System), a community-made framework that lets modders hook into the game with Lua scripts. UE4SS is not preinstalled on Spawnly servers, and there's currently no confirmed way to set it up on a hosted Palworld server here.
The File Manager (Files tab) is the only way to upload files to a Palworld server on Spawnly. Treat any UE4SS setup as advanced, unsupported territory — there's no guarantee it or a given mod will run correctly, and we can't walk you through a verified path today.
Good to Know: PalWorldSettings.ini
Separately from mods, Palworld generates its own server settings file the first time it boots, at Pal/Saved/Config/LinuxServer/PalWorldSettings.ini. It contains a [/Script/Pal.PalGameWorldSettings] block with settings like RCON access, ServerPlayerMaxNum, and ServerName. You can open and edit this directly through the File Manager — it's a normal config file, not a mod, but it's the main place to tune how your server behaves without needing any mod framework at all. Like any config change, edits here need a server restart to take effect.
Next Steps
If you do experiment with manual files, take a backup first — see Managing Backups & Restoring Your Server. For server-visibility settings and general setup, see Getting Started with Your Palworld Server.
