PolyMC is a custom launcher for Minecraft that focuses on predictability, long term stability and simplicity.

This is a fork of the MultiMC Launcher and not endorsed by MultiMC. If you want to read about why this fork was created, check out our FAQ page.

Installation

Development Builds

There are per-commit development builds available here. These have debug information in the binaries, so their file sizes are relatively larger. Portable builds are provided for AppImage on Linux, Windows, and macOS.

For Debian and Arch, you can use these packages for the latest development versions:
polymc-git polymc-git
For flatpak, you can use flathub-beta

Help & Support

Feel free to create an issue if you need help. However, you might find it easier to ask in the Discord server.

PolyMC Discord

For people who don't want to use Discord, we have a Matrix Space which is bridged to the Discord server:

We also have a subreddit you can post your issues and suggestions on:

Forking/Redistributing/Custom builds policy

We don't care what you do with your fork/custom build as long as you follow the terms of the license (this is a legal responsibility), and if you made code changes rather than just packaging a custom build, please do the following as a basic courtesy:

  • Make it clear that your fork is not PolyMC and is not endorsed by or affiliated with the PolyMC project (https://polymc.org).
  • Go through CMakeLists.txt and change PolyMC's API keys to your own or set them to empty strings ("") to disable them (this way the program will still compile but the functionality requiring those keys will be disabled).

If you have any questions or want any clarification on the above conditions please make an issue and ask us.

Be aware that if you build this software without removing the provided API keys in CMakeLists.txt you are accepting the following terms and conditions:

If you do not agree with these terms and conditions, then remove the associated API keys from the CMakeLists.txt file by setting them to an empty string ("").

All launcher code is available under the GPL-3.0-only license.

The logo and related assets are under the CC BY-SA 4.0 license.
