Modrinth vs PolyMC

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.

PolyMC is a free, open-source Minecraft launcher for Linux, macOS, and Windows. It manages multiple accounts, mods, and separate instances, with each instance keeping its own folder for mods, resource packs, settings, and other files. The launcher supports Forge, Fabric, LiteLoader, and Quilt, plus modpack installation from CurseForge, Technic, FTB, FTB Legacy, and Modrinth. Individual mods can be installed from CurseForge and Modrinth for the selected loader and game version. PolyMC also manages worlds, resource packs, shader packs, and Java runtimes, and provides logs plus a way to stop Minecraft after crashes or freezes. Users can customize the instance window and theme. The project says its Qt-based launcher remains light on system resources. PolyMC is licensed under GPL-3, while its logo and related assets use CC BY-SA 4.0. The current macOS build supports Apple Silicon; Intel users need the legacy universal build.
