The PolyMC Launcher is a free and open-source launcher designed exclusively for modded versions of Minecraft that focus on simplicity, user freedom, and long-term stability. It enables you to effortlessly manage many installs, accounts, instances, and Minecraft mods simultaneously.

In addition to letting you manage accounts and Minecraft mods, the PolyMC Launcher provides a wide range of useful functions. You can quickly end a Minecraft session if it freezes or crashes using the launcher. Additionally, you can edit, rename, and even copy the features of your Minecraft worlds. All versions of Minecraft and snapshots that the normal Minecraft launcher supports are also supported by the PolyMC Launcher.

Additionally, this launcher incorporates Forge and Fabric, enabling mod management, automatic installation, and downloading of various Minecraft versions. Additionally, you can share your Minecraft instances with other players by importing and exporting them. Additionally, you can manage in-game screenshots, server and client text logs, and more.


Over 30 features are available in PolyMC Launcher to enhance your gaming experience.
