You usually install Palworld mods through a mod framework such as UE4SS and the respective mod file from a trusted source. The decisive factor is whether the mod runs only server-side or also has to be installed on every client. Plan a backup before making changes and always check compatibility after updates.

Requirements

Before setting up mods on a Palworld server, you should clarify which Palworld version is running on the server and client and whether the desired mod supports exactly that version. Mods often directly affect game or engine functions. Even a small game update can therefore be enough to stop a mod from loading or trigger unexpected behavior.

You need access to the Palworld server directory, the ability to restart the server, and a way to upload or replace files cleanly. With paid multi-game hosting such as game-serverhosting, the most important part is that you can perform changes in a controlled way, use backups, and roll back traceably if problems occur.

The primary source for the mod framework is the official UE4SS repository: documentation at github.com. Read the notes there about the matching version and installation before replacing files on the server.

Mod Framework: UE4SS

Palworld is based on Unreal Engine and uses UE4SS as a mod loader for many mods:

  1. Download UE4SS
  2. Extract it into the Palworld directory
  3. Restart the server

Make sure you do not install multiple UE4SS versions over each other without checking old files. If a mod names a specific UE4SS version, that information takes priority over general recommendations. Also keep a copy of the original server files or a full backup before installing the framework.

Finding Mods

Popular sources:

Only download mods from sources where the description, version, change date, and installation instructions are traceable. Pay particular attention to whether the mod is suitable for dedicated servers or only changes the local client. Also read comments or changelogs if many users report errors after a Palworld update.

If you also run other games with mods, comparable workflows can help with classification: the guide Install Factorio Mods on the Server shows the focus on version parity and mod sync, while Install 7 Days to Die Mods explains typical differences between server and client files.

Installation on Server and Client

The basic installation remains simple, but you should carry it out in a controlled way:

  1. Download the mod
  2. Extract it into the mods folder
  3. Restart server and client

Do not blindly extract the file into just any folder. Many mods come with a fixed folder structure. For example, if the download contains its own mod folder, it usually has to be copied completely into the mods folder. If the description also mentions files for Content, Paks, or another subdirectory, follow the mod instructions and document which files you changed.

Then install the same mod version on the client if the mod requires it. This affects many mods that change display, controls, items, Pals, or gameplay logic. If only the server is modified but the client expects unchanged data, connection problems, missing functions, or crashes can occur.

Popular Mods

Mod Description
Simple Spawner Spawn Pals at a desired position
Increased Stack Size Larger item stacks
Flying Mount Anywhere Fly anywhere
Better Stats Improved stats display
Auto Breeding Automatic breeding

This table is for orientation, not a blanket recommendation. Check every mod individually for current status, dependencies, and server suitability. Mods that change spawns, stack sizes, or breeding in particular can significantly affect the feel and balance of a shared world. Coordinate such changes with your group before enabling them on a production server.

Server-Side Mods

Some mods can be installed only on the server:

  • Spawn rate adjustments
  • Item balance changes
  • Custom Pal definitions

Server-side mods are practical when you want to control rules centrally. Still, “server-side” does not automatically mean clients are never affected. As soon as new data, changed displays, or local files are required, other players also need matching installations. The mod description is the authoritative source here.

Checking the Result

Restart the server after installation and first connect with a single test client. Check whether the server fully boots, whether the world loads, and whether the mod function is actually available in the game. Also check the server logs for loading errors, missing dependencies, or notes about incompatible files.

If several mods are installed, do not test everything at the same time. Enable UE4SS first, then one mod, then the next. This helps you find out faster which change triggers an error. For larger mod setups, a simple list with mod name, version, source, and installation date is worthwhile.

Troubleshooting

If the server does not start, remove the recently added mod files and check whether the server loads again without that change. If the error remains, restore the backup from before the UE4SS installation and start with a fresh installation.

If players cannot connect, compare Palworld version, UE4SS version, and mod version between server and client. Problems often arise because a client uses an older or newer mod file. If only individual players are affected, the cause is usually in the local client setup.

If a mod is not visible in the game, check the folder structure. A common error is a double-nested folder, for example Mods/ModName/ModName/.... Also check whether the mod needs additional configuration files or only loads after a full restart.

Important

  • Compatibility: Mods must match the current Palworld version
  • Updates: After Palworld updates, check whether mods still work
  • Client sync: Most mods also have to be installed on the client

Verification, Limits, and a Safe Rollback

The guide “Installing Palworld Mods – Server and Client” applies to the server type described in the article and the version state visible at the time of review. Menu names, available versions, mod or plugin compatibility, and required resources can differ after updates. Therefore, do not transfer any values unchecked to another game, loader, or server version.

Before making changes to the world, savegame, configuration, or extensions, create a backup of the affected files. Then change only one related step and test it with the same client and server version you want to play with later.

Checkpoint Expected Result Abort and Rollback
Server start The server reaches the ready-to-run state without a new error message. If startup errors occur, revert the change and restore the last backup.
Connection test A test account can connect via the address shown in the panel. If version or connection errors occur, compare version, port, and approvals again.
Function test The specifically changed function works without damaging existing world or game data. If side effects occur, stop the server and restore backed-up files.

A successful individual test is not a performance or availability guarantee. World size, mods, plugins, player count, network path, and simultaneous load can change the result. Document the version, change, and test result so you can understand later deviations.

FAQ

Do I need UE4SS for all Palworld mods?

No, not necessarily. Many Palworld mods use UE4SS, but the specific requirement is listed in the description of the respective mod. Do not install a framework on suspicion if the mod specifies a different method.

Do all players have to install the same mods?

For many mods, yes, especially when client files, displays, items, or gameplay functions are changed. Pure server adjustments can work without a client mod, but you have to check this per mod.

What should I do after a Palworld update?

Do not immediately continue with the old mod set. First check whether UE4SS and the installed mods match the new Palworld version. If unclear, test on a copy or wait for updated mod versions.

Can I install several mods at the same time?

Yes, but install them step by step. After each mod, you should test server start, connection, and basic function. This helps you find conflicts faster and means you do not have to search the entire setup when errors occur.

Which internal guides help with other mod servers?

For similar workflows, the guides on V Rising Mods with BepInEx and Satisfactory Client Mods with SMM are helpful because they also cover dependencies, client files, and version parity.
