Heimdall
Mod Assistant.
Just trying to make
mod management easier.
Your games. Your mods. A little more order.
A companion for the worlds you make your own.
Windows desktop app · Browser configuration workspace
BUILT FOR YOUR COLLECTION
LESS HOUSEKEEPING. MORE PLAYING.
Keep track of the
worlds you change.
Modding should feel like possibility. Keeping everything organized shouldn’t get in the way.
Heimdall Mod Assistant brings supported mod folders, saved selections, and reversible enable/disable controls into one place. Compatibility depends on the game, its loader, and the mod—not just a switch.
Make it your own.
Review installed mods, enable or disable them, and check available metadata for updates and possible conflicts.
Keep your choices.
Export your configuration. Review it in your browser, then bring the file to another computer with the desktop assistant.

A few things to know.
Can the browser manage installed mods?
The browser workspace edits portable configuration files. It cannot scan your PC or install mods. Export your configuration and import it into the Windows assistant to review and apply supported changes.
Will this work with every game?
No. Game detection and mod support are different. The assistant works with specific folder-based mod systems, and some games need a separate mod loader. Read the guide before installing.
What happens if I cancel?
Paid benefits end when your paid access expires. You return to free; your mod files are not deleted. Restore and configuration export remain available.
Does Heimdall sell or own the mods?
No. Mods belong to their creators and remain subject to their licenses and distributor rules. Your membership supports the assistant, not ownership of third-party mods.
