LabyMod vs PolyMC

LabyMod 4 is a Minecraft Java Edition client that bundles more than 100 mods into one installation. Its launcher manages multiple instances and game versions, switches accounts, and can start LabyMod, vanilla Minecraft, Forge, Fabric, and other modloaders. A browser covers CurseForge, Modrinth, and more; users can build modpacks or import instances from other launchers. The client supports more than 20 Minecraft Java Edition versions, from 1.8.9 through the current release. Players can choose Fancy or classic Vanilla themes and customize screens. Proximity Voice offers positional audio, push-to-talk or voice activation, and private voice channels without server plugins. The server list includes HD icons and backgrounds, quick join, folders, and live player counts and status. Users can invite friends into a singleplayer world without configuring a server or port forwarding; the product page says the host IP stays protected. The client is free for Windows, macOS, and Linux, but requires a genuine Microsoft Minecraft Java Edition account. A separate iOS and Android app manages profiles, streaks, LabyCoins, and cosmetics; the client itself has no official mobile version.

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.
