Modrinth Launcher | Install Minecraft Mods in One App

This open-source desktop app pulls your modded Minecraft setup into one place. It handles installing mods, keeping them updated, and packaging modpacks without making you juggle folders or external tools. You sign in with your Microsoft account, pick a modpack or build your own, and play.

The app stays in beta, and the team ships new builds often. The latest release landed in June 2026, so the project is actively maintained right now.

Why pick this launcher for modded Minecraft

Instead of stitching together a launcher, a mod manager, and a modpack builder, you get all three in one window. The app talks to its integrated mod catalog, so adding a mod is a click rather than a manual download and folder drop. Multiple Microsoft accounts can live side by side, which helps if you share the PC or juggle separate profiles.

Built-in mod and modpack management

One-click mods

Inside each instance you can add, remove, and update mods with a single click. The launcher grabs the matching file for your loader, so you skip the version hunting. When a mod ships a new build, the app flags it and lets you pull the update without rebuilding the instance.

Build and share modpacks

You can assemble your own modpack from the integrated catalog, then export it to share with friends or publish for anyone to install. A built-in modpack browser lets you discover community packs and try them in a couple of clicks.

Import profiles from other launchers

Switching from GDLauncher, MultiMC, or a similar launcher is painless. The profile importer reads your existing instances and pulls them in, so you keep your setups without starting over. It is the fastest path if you already have a working modded setup elsewhere.

Play offline and follow projects

Instances stay runnable without an internet connection, so you can play your mods on the go or when your connection drops. Following a project saves it to your account and surfaces updates as they land, which is handy for tracking the mods you care about. The launcher is fully integrated with its web catalog, so everything you follow on the site is ready inside the app.

Lightweight on RAM

The app itself uses roughly 150 MB of RAM, which means it runs comfortably on older hardware. You do not need a high-end machine just to manage your mods.

How to install it

1. Download the installer for your operating system from the project page. Windows and macOS builds are listed directly, and Linux users can grab the AppImage, DEB, or RPM package, or install the Flatpak from Flathub.
2. Run the installer and open the app.
3. Sign in with your Microsoft account. You can add multiple accounts if you share the machine or run different profiles.
4. Create a new instance or import an existing profile, then add your mods or pick a modpack from the browser.
5. Hit play. The launcher downloads the right Minecraft and loader files for you.
