Valheim Client-Side Mods: Check Compatibility Before You Join
Check Valheim client-side mods against package requirements, dependencies and server rules before you join a shared world.
You will need
- A current Valheim installation and the exact mod page or release
- The server administrator’s rules and contact information
- A separate mod-manager profile and an approved test world
A “client-side” label on Valheim mods tells you where a package says its files belong; it does not prove that the mod works with your server, fits the group’s rules, or is compatible with the current game build. Check the exact package and dependencies, get the administrator’s approval, and test your profile on a separate world before joining the campaign. This guide shows what to verify and record without treating any community mod as officially supported or universally safe.
Evaluate Valheim client-side mods one package at a time#
Start with the behavior you want, then decide whether it is acceptable for the shared world. “Client-side” usually describes where the package installs or runs. It does not automatically mean that the change is purely cosmetic, invisible to other players, compatible with every server, or allowed by its administrator.
Iron Gate says community mods are unofficial, unsupported, and used at the player’s own risk. The official mod policy does not certify particular packages or give a blanket permission rule for other people’s servers. That decision belongs to the server’s rules and the players who share the world.
| What you find | What it tells you | What it does not prove |
|---|---|---|
| A “client-side” tag | How a catalog classifies the package | That its current release works on your build or server |
| A maintainer says “not needed on the server” | The stated installation scope | That the server owner allows its effect |
| A mod manager can install the package | That the manager can organize its files | That the package is compatible or harmless in multiplayer |
Keep the terms separate in your notes: install scope is where files go; compatibility is whether this exact setup works; permission is whether the group allows it. For crew-wide mod planning, build a compatible multiplayer mod plan before anyone changes a shared campaign.
Read the current package page before you install#
Open the exact project page and release notes, not just a search snippet or a list of “best client mods.” Confirm the package author, project name, release version, date, supported game version if stated, install scope, dependencies, and any instructions for a dedicated server. Save the URL for the version you intend to try; similar names can point to forks with different requirements.
For example, the current AzuHoverStats package page identifies version 1.1.9 as client-only and says it is not needed on the server. That is useful evidence about what its maintainer documents for installation. It is not a test report for every Valheim version, server, platform, or other plugin in your profile.
Thunderstore’s Client-side and Server-side tags help you discover packages, but they are not compatibility labels. If the package page lacks a clear release note or the instructions do not match your planned setup, record the answer as “not stated” and ask the maintainer or administrator. Do not fill the gap with a comment from an old guide.
Check dependencies, loader and game build#
Read the package’s dependency list and every required dependency’s own page. Record versions and supported game builds together. A plugin can have a client-side installation while still requiring a loader, a library, configuration files, or a specific server-side counterpart. If the package documents version checks or synchronized configuration, note how that affects your server.
The Valheim BepInEx pack is a community-maintained loader package; its page currently lists version 5.4.2351. The pack’s current version does not establish that a particular plugin supports your game build. Check each plugin separately, including its changelog and dependency versions. Where the maintainer has not named your build, leave compatibility unconfirmed.
Use a short manifest before you install:
| Record | Example entry |
|---|---|
| Package and author | Exact project name and maintainer |
| Release | Version plus its release-page URL |
| Game build | The client build you intend to use |
| Dependencies | Exact required package names and versions |
| Install scope | Client, server, both, or not stated |
| Open checks | Admin approval, server build, test result |
If two pages disagree about a dependency or build, stop and resolve the conflict first. A profile containing “the latest versions” is not reproducible after a patch or a friend’s reinstall.
Ask the server admin what is allowed#
Ask before joining with a plugin that reveals extra information, changes combat or movement, automates an action, or affects building and resource collection. Even a package described as client-only can change one player’s experience in a way the group considers unfair. The administrator may also want to keep the world vanilla or allow only a written list.
The official Valheim 1.0 FAQ says console versions do not have official mod support. That statement does not prove that every mixed-platform server rejects every PC player’s client mod, or that a given package supports consoles. If your group includes console players, keep their route explicitly unresolved until the package documentation and the server owner answer the question.
You can ask the admin for four things: whether client mods are allowed at all; which behaviors are out of bounds; whether the server checks versions or synchronized settings; and where to report a problem. If the answer is unclear, do not use the mod in that world yet. A public server listing or a successful connection does not grant permission to use every plugin.
Keep vanilla and modded profiles separate#
Use a mod manager’s separate profile for the experiment so you can return to an unmodified client without hunting through files. The r2modman profile documentation describes profile organization and export. A profile export records the manager’s mod setup; it is not a backup of your Valheim character or the server’s world.
Keep a clean vanilla profile, the proposed modded profile, and the package manifest distinct. Do not copy files between profiles while the game or server is running. If a package says it changes saved data or requires a server component, get the administrator’s instructions before you experiment.
Test the exact profile on an approved disposable world#
Treat the first join as a test, not as approval for the main campaign. Ask the administrator for a disposable server or a separate copy of the world and confirm that your trial is allowed. Test the exact client profile and server configuration you plan to use; changing one dependency or game build creates a different combination.
Record the starting versions
Write down the game build, mod-manager profile, loader, every package release, and the server build. Save the relevant package-page links with the record.
Launch the clean profile once
Confirm the vanilla profile still opens before adding the proposed package. If it no longer starts cleanly, stop and repair that profile before testing mods.
Join only the approved test world
Follow the server administrator’s instructions. Confirm that you can join, then check the specific feature the package claims to add. A server process starting is not proof that your client joined or that the feature works.
Record what happened and stop on unexpected changes
Note the exact profile, client/server versions, visible behavior, and any relevant error. If the package changes the world or behaves differently than described, leave the campaign world untouched and ask the administrator before trying again.
This article does not certify the example packages in a live multiplayer session. The useful result is a test record for your own game build, server, and approved profile. If you cannot access a safe test world, leave the package unapproved rather than treating its tag or popularity as a successful join test.
Record what worked and remove it by the maintainer’s steps#
Keep the working release list with the date, game build, server version, test world, and administrator’s decision. Assign one person to check changes before updating. After a Valheim patch or package update, revisit the maintainer’s release notes and repeat the test that matters; “it worked once” applies only to the versions you recorded.
Before installing, find the maintainer’s removal instructions and identify how to disable the profile. Do not assume deleting a package reverses its effects in a saved world. If you see errors, unexpected gameplay changes, or a mismatch between the published requirements and your test, switch back to the clean profile and contact the server owner. Keep the unresolved package out of the campaign until the group agrees on a tested version.
A personal client plugin rarely gives you a reason to change server hosts. If your group’s verified needs shift to keeping a dedicated world online and managing its server settings or restarts, compare the Valheim hosting options. Moving the server does not make an unsupported client mod compatible.
Quick answers
Are client-side Valheim mods allowed on servers?
There is no universal permission rule in the official docs. Check the exact package requirements and ask the server administrator before joining.
How do I find a client-side Valheim mod?
Read the exact package page, release notes and dependency list. A catalog tag is a clue, not proof that it works with your game build or server.
Can a client-only mod affect multiplayer fairness?
It can change what a player sees or can do, so judge the documented behavior and agree on it with the server administrator before testing.
