Valheim 1.0 brings the Deep North and marks the game’s full release after years in Early Access. For players using mods, however, a major update also brings an important question: will existing Valheim mods still work with 1.0?

Iron Gate does not officially support Valheim mods, so compatibility with new game versions is never guaranteed. Some mods may continue working normally, while others could require updates from their developers before they function correctly again.

If you run a modded Valheim server, understanding how updates affect mods, dependencies, and multiplayer compatibility can help protect your world and avoid unexpected problems.

Will Existing Valheim Mods Work With 1.0?

There is no guarantee that existing mods will work immediately with Valheim 1.0.

Mods can depend on specific parts of the game’s code, assets, systems, or modding frameworks. When a major game update changes those areas, an older mod may stop loading correctly, produce errors, or behave differently than intended.

This does not mean every mod will break. Smaller quality-of-life mods may require few changes, while larger mods that add items, creatures, building pieces, progression, or other gameplay systems could need more work.

The safest approach is to check each mod you use and wait for its developer to confirm compatibility with 1.0.

Does Valheim 1.0 Have Official Mod Support?

Valheim 1.0 does not include official mod support.

Iron Gate allows the community to create and use mods, but modding remains unofficial. Valheim 1.0 does not include Steam Workshop integration

Adding Valheim server mods can be done with the use of frameworks such as BepInEx, with mods commonly distributed through platforms like Thunderstore. These frameworks and dependencies may also need to be compatible with the new game version before some mods can function.

What Happens To Modded Valheim Servers After The Update?

A Valheim server can update to 1.0 while still containing older mod files, but that does not mean those mods will continue working correctly.

Depending on the mod, an outdated installation could fail to load, generate console errors, prevent features from working, or cause compatibility problems when players join.

This matters most if your server depends heavily on mods for normal gameplay. A small client-side interface mod is very different from a mod that adds custom items, changes progression, or modifies the world.

Before updating a heavily modded server, make a complete backup of your world and configuration.

Should You Remove Your Mods Before Updating To 1.0?

You do not necessarily need to delete every mod before Valheim 1.0.

Instead, review your mod list and determine which mods have been confirmed to work with the new version. Keep track of dependencies too, because one mod may rely on BepInEx or another library that also needs an update.

A good process is to:

  • Back up your Valheim world before updating
  • Record the mods and versions currently installed
  • Check each mod for a 1.0-compatible update
  • Update BepInEx and other required dependencies when compatible versions are available
  • Update individual mods before enabling them again
  • Test the server before allowing everyone to reconnect

If compatibility is unclear, temporarily leaving a mod disabled may be safer than assuming it still works.

Do Players And Servers Need The Same Valheim Mods?

It depends on the mod.

Some Valheim mods work entirely on the client and only change the experience for that player. Others need to be installed on the dedicated server, while certain multiplayer mods require both the server and connecting players to use compatible versions.

Server owners should always check the installation and multiplayer requirements listed by the mod developer.

If players suddenly cannot connect after an update, mismatched mod versions or missing dependencies are among the first things worth checking.

Will Valheim 1.0 Mods Work With Console Crossplay?

Console support makes modding more complicated in Valheim 1.0.

PlayStation 5 and Nintendo Switch 2 join the existing platforms for the full release, but Valheim 1.0 does not provide mod support on consoles. Console players therefore cannot simply install the same BepInEx setup and PC mods used by a heavily modded server.

If your goal is reliable crossplay between PC and console players, a vanilla or lightly customized server is the safer option.

PC groups that want a heavily modded experience may need to prioritize mod compatibility over universal crossplay, depending on the requirements of the mods they use.

How To Prepare A Modded Valheim Server For 1.0

The most important thing is not to treat the 1.0 update like a normal restart when your server relies on many mods.

Start by creating a backup. Then review your mod list and identify the mods your server cannot function without. Check for versions confirmed to work with Valheim 1.0.

Once your core mods are compatible, test the server before bringing your entire community back online. Check the console for errors, make sure important items and systems still work, and confirm players can connect normally.

Taking a little extra time after the update can be much easier than trying to diagnose several broken mods at once.
