Launching Soon
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. No installer, 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
Hit Install on any mod page on openmods.net — the manager catches the deep link, downloads the right asset, and unpacks it into the right place.
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 available? You get a badge and a one-click Update right on the row.
Clean uninstall
Every file the manager creates is tracked. Removing a mod walks the list in reverse and only deletes what it actually put there — shared folders are left alone.
Smart asset picking
Mods that ship a separate zip per game (e.g. .SN.zip vs .BZ.zip)
automatically pick the right one based on which game you're installing into.
Download history
Every successful install logged with version, size, time, and a shortcut back to the install folder or the mod's web 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 & run
Single self-contained executable. No installer, no .NET runtime install, no admin rights.
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 install.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.
Every build is a single self-contained executable plus its assets. No .NET install required on the target machine.
