Mod Organizer 2 vs Modrinth

Mod Organizer 2 is a free, open-source Windows tool for managing game mod collections through a virtualized setup. It supports installing and uninstalling mods, organizing profiles, detecting conflicts, and automatic updates. The project describes it as a tool for people who experiment with mods and says it can handle collections of arbitrary size. Supported games include 64-bit titles such as Skyrim Special Edition and Fallout 4, along with the 32-bit games supported by Mod Organizer 1. Its basic games plugin can detect installations from Steam, GOG, Origin, Epic Games or Legendary, and EA Desktop. A mod data checker can identify and correct archive layouts for automatic installation. Downloads are available through GitHub Releases and Nexus Mods; the installer can also create a portable installation. Version 2.5.0 requires Windows 10 1809 or newer, or Windows 11. The virtual filesystem does not work with Windows Store or Gamepass packaging, so those versions of otherwise supported games are not usable. The community-maintained project is licensed under GPL-3.0.

Modrinth hosts user-created projects for Minecraft: Java Edition, including mods, plugins, data packs, shaders, resource packs, and modpacks. Search and filters help visitors find projects, including by game version. The open-source Modrinth App is a desktop launcher for installing, removing, and updating mods, and sharing modpacks. It is available for Windows, macOS, and Linux, though it is currently in public beta and Linux versions may have issues on some systems and configurations. Modrinth’s open API supports launcher integrations including ATLauncher, MultiMC, and Prism Launcher. Creators can manage team roles and permissions, receive ad revenue, and review page-view, download, and revenue reports. Modrinth Hosting supports Minecraft Java versions back to 1.2.5 and loaders including Fabric, Quilt, Forge, NeoForge, Paper, and Purpur, subject to version support. A free offer provides a 3 GB server for five days for US servers, with no credit card required. The platform has a free plan; Modrinth+ costs $4.99 a month, and customized hosting plans start at $5 a month.
