Beta is now live, expect some bugs!
Manage your mods.
Effortlessly.
OpenMods Manager is the desktop companion to openmods.net. One-click install, automatic updates, and clean uninstall — for every game in your library.
verified Free. Per-user install, no admin rights. Requires a free OpenMods account to sign in.
Everything in one place.
Stop juggling zip files and game folders. The manager handles the boring parts so you can focus on playing.
One-click install, straight from the browser.
Hit Install on any mod page on openmods.net — your browser hands the URL to the manager, which downloads the right asset and unpacks it where it belongs.
Multi-game library
Subnautica, Below Zero, Minecraft, Stardew Valley, Satisfactory and more — link each game's folder once and you're done.
Update detection
Every installed mod is checked against the catalog. New version? Badge plus one-click Update right on the row.
Smart asset picking
Mods that ship a zip per game (.SN.zip vs .BZ.zip) auto-resolve to the right one for the game you're installing into.
Clean uninstall
Every file the manager writes is tracked. Removing a mod walks the list in reverse — shared folders are left alone.
Download history
Every install logged with version, size, time, and a shortcut back to the install folder or the mod's page.
How it works
From zero to modded in 4 steps.
No background services. No auto-launching. Open it when you need it, close it when you’re done.
Download & install
Tiny per-user installer on Windows and macOS, portable zip on Linux. Auto-updates from there.
Sign in with API key
Generate one on openmods.net → API Management and paste it in. Stored encrypted, locally only.
Link your games
Point the manager at each game's install folder once (e.g. D:\Steam\…\Subnautica).
Install from the web
Hit Install on any mod page. Your browser hands the URL to the manager. Done.
Privacy & security
Built in the open. Run on your terms.
Your game library, install paths, and API key stay on your machine, encrypted at rest. Any diagnostics or crash reports we ever add will be off by default and one toggle away — what gets sent is yours to see.
- lock
AES-256 at rest
Your API key, library, and install records are encrypted in
storage.dat. On Windows the key is wrapped with DPAPI bound to your user account. - https
HTTPS everywhere
Every call to openmods.net and to GitHub release URLs goes over TLS.
- visibility
Source-available
Every line is published for transparency and security review. Audit it before you trust it.
- block
No background services
Single-instance app. Doesn't run a server, doesn't open ports, doesn't auto-launch on boot.
Honest threat model
What we protect — and what we don't.
Protected
A second user on the same machine can't read your encrypted store.
Protected
Mod files only land inside the game folder you linked, where the mod's openmods.json says.
Not protected
Malware already running as you, or anyone with your unlocked session. Treat the API key like a password — revoke it on the website if leaked.
Downloads
Pick your platform.

Linux setup
The Flatpak above is the easiest path — it bundles its own webview, so no system setup is needed.
If you'd rather run the portable zip, you'll need to install libwebkit2gtk-4.1 manually.
Flatpak · Any Linux distro
flatpak install --user OpenModsManager-linux-x64.flatpak
flatpak run net.openmods.managerSurvives SteamOS image updates. Auto-updates handled by the in-app updater. Appears in your app menu after install.
Or, portable zip (needs webkit installed)
Debian · Ubuntu · Mint
sudo apt install libwebkit2gtk-4.1-0Steam Deck · SteamOS · Arch
sudo steamos-readonly disable
sudo pacman-key --init
sudo pacman-key --populate archlinux
sudo pacman -Sy webkit2gtk-4.1
sudo steamos-readonly enable
On Steam Deck, run the commands in Desktop Mode → Konsole. The steamos-readonly
toggle is required because SteamOS keeps its system partition read-only by default. The two pacman-key
lines initialize the keyring (skip them only if you've already done so — you'll know if you have).
After install, extract the zip anywhere and double-click OpenModsManager (or run it from a terminal).
