Prism Launcher

Prism Launcher is a custom launcher for Minecraft that allows you to easily manage multiple installations of Minecraft at once.

This is a fork of the MultiMC Launcher and is not endorsed by it.


Packaging status
  • All downloads and instructions for Prism Launcher can be found on our Website.
  • Last build status can be found in the GitHub Actions tab (this also includes the pull requests status).

Development Builds

Please understand that these builds are not intended for most users. There may be bugs, and other instabilities. You have been warned.

There are development builds available through:

  • GitHub Actions (includes builds from pull requests opened by contribuitors)
  • nightly.link (this will always point only to the latest version of develop)

These have debug information in the binaries, so their file sizes are relatively larger.

Prebuilt Development builds are provided for Linux, Windows and macOS.

For Arch, Debian, Fedora, OpenSUSE (Tumbleweed) and Gentoo, respectively, you can use these packages for the latest development versions:

prismlauncher-git prismlauncher-git prismlauncher-git
prismlauncher-nightly prismlauncher-nightly prismlauncher-9999

These packages are also available to all the distributions based on the ones mentioned above.

Forking/Redistributing/Custom builds policy

You are free to fork, redistribute and provide custom builds 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 Prism Launcher and is not endorsed by or affiliated with the Prism Launcher project (https://prismlauncher.org).
  • Go through CMakeLists.txt and change Prism Launcher'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.

If you are just building Prism Launcher for your distribution, please make sure to set the Launcher_BUILD_PLATFORM to a slug representing your distribution. Examples are archlinux, fedora and nixpkgs.

Note 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 ("").
